Can you run MSR on Home Assistant OS ?
cw-kidC
Looking at using Home Assistant for the first time, either on a Home Assistant Green, their own hardware or buying a cheap second hand mini PC. Sounds like Home Assistant OS is linux based using Docker for HA etc. Would I also be able to install things like MSR as well on their OS ? On the same box? Thanks.

How to upgrade from an old version of MSR?
cw-kidC
Hello I haven't updated my installation of MSR in a very long time. Its a bare metal Linux install currently on version 24366-3de60836 I see the latest version is now latest-26011-c621bbc7 I assume I cannot just jump from a very old version to the latest version? Or can I? Thanks

Self test
CatmanV2C
Having been messing around with some stuff I worked a way to self trigger some tests that I wanted to do on the HA <> MSR integration This got me wondering if there's an entity that changes state / is exposed when a configured controller goes off line? I can't see one but thought it might be hidden or something? Cheers C

Access control - allowing anonymous user to dashboard
tunnusT
Using build 25328 and having the following users.yaml configuration: users: # This section defines your valid users. admin: ******* groups: # This section defines your user groups. Optionally, it defines application # and API access restrictions (ACLs) for the group. Users may belong to # more than one group. Again, no required or special groups here. admin_group: users: - admin applications: true # special form allows access to ALL applications guests: users: "*" applications: - dashboard api_acls: # This ACL allows users in the "admin" group to access the API - url: "/api" group: admin_group allow: true log: true # This ACL allows anyone/thing to access the /api/v1/alive API endpoint - url: "/api/v1/alive" allow: true session: timeout: 7200 # (seconds) rolling: true # activity extends timeout when true # If log_acls is true, the selected ACL for every API access is logged. log_acls: true # If debug_acls is true, even more information about ACL selection is logged. debug_acls: true My goal is to allow anonymous user to dashboard, but MSR is still asking for a password when trying to access that. Nothing in the logs related to dashboard access. Probably an error in the configuration, but help needed to find that. Tried to put url: "/dashboard" under api_acls, but that was a long shot and didn't work.

VEC Virtual Switch Auto Off
S
I use Virtual Entity Controller virtual switches which I turn on via webhooks from other applications. Once a switch triggers and turns on, I can then activate associated rules. I would like each virtual switch to automatically turn off after a configurable time (e.g., 5 seconds, 10 seconds). Is there a better way to achieve this auto-off behavior instead of creating a separate rule for each switch that uses the 'Condition must be sustained for' option to turn it off? With a large number of these switches (and the associated turn-off rules), I'm checking to see if there is a simpler approach.If not, could this be a feature request to add an auto-off timer directly to the virtual switches.

Upcoming Storage Change -- Got Back-ups?
toggledbitsT
TL;DR: Format of data in storage directory will soon change. Make sure you are backing up the contents of that directory in its entirety, and you preserve your backups for an extended period, particularly the backup you take right before upgrading to the build containing this change (date of that is still to be determined, but soon). The old data format will remain readable (so you'll be able to read your pre-change backups) for the foreseeable future. In support of a number of other changes in the works, I have found it necessary to change the storage format for Reactor objects in storage at the physical level. Until now, plain, standard JSON has been used to store the data (everything under the storage directory). This has served well, but has a few limitations, including no real support for native JavaScript objects like Date, Map, Set, and others. It also is unable to store data that contains "loops" — objects that reference themselves in some way. I'm not sure exactly when, but in the not-too-distant future I will publish a build using the new data format. It will automatically convert existing JSON data to the new format. For the moment, it will save data in both the new format and the old JSON format, preferring the former when loading data from storage. I have been running my own home with this new format for several months, and have no issues with data loss or corruption. A few other things to know: If you are not already backing up your storage directory, you should be. At a minimum, back this directory up every time you make big changes to your Rules, Reactions, etc. Your existing JSON-format backups will continue to be readable for the long-term (years). The code that loads data from these files looks for the new file format first (which will have a .dval suffix), and if not found, will happily read (and convert) a same-basenamed .json file (i.e. it looks for ruleid.dval first, and if it doesn't find it, it tries to load ruleid.json). I'll publish detailed instructions for restoring from old backups when the build is posted (it's easy). The new .dval files are not directly human-readable or editable as easily as the old .json files. A new utility will be provided in the tools directory to convert .dval data to .json format, which you can then read or edit if you find that necessary. However, that may not work for all future data, as my intent is to make more native JavaScript objects directly storable, and many of those objects cannot be stored in JSON. You may need to modify your backup tools/scripts to pick up the new files: if you explicitly name .json files (rather than just specifying the entire storage directory) in your backup configuration, you will need to add .dval files to get a complete, accurate backup. I don't think this will be an issue for any of you; I imagine that you're all just backing up the entire contents of storage regardless of format/name, that is the safest (and IMO most correct) way to go (if that's not what you're doing, consider changing your approach). The current code stores the data in both the .dval form and the .json form to hedge against any real-world problems I don't encounter in my own use. Some future build will drop this redundancy (i.e. save only to .dval form). However, the read code for the .json form will remain in any case. This applies only to persistent storage that Reactor creates and controls under the storage tree. All other JSON data files (e.g. device data for Controllers) are unaffected by this change and will remain in that form. YAML files are also unaffected by this change. This thread is open for any questions or concerns.

Possible feature request 2?
CatmanV2C
Just another thought. Adding devices from my Home Assistant / Zigbee2MQTT integration. Works perfectly but they always add as their IEEE address. Some of these devices have up to 10 entities associated, and the moment they are renamed to something sensible, each of those entities 'ceases to exist' in MSR. I like things tidy, and deleting each defunct entity needs 3 clicks. Any chance of a 'bulk delete' option? No biggy as I've pretty much finished my Z-wave migration and I don't expect to be adding more than 2 new Zigbee devices Cheers C

Reactor (Multi-System/Multi-Hub) Announcements
toggledbitsT
Build 21228 has been released. Docker images available from DockerHub as usual, and bare-metal packages here. Home Assistant up to version 2021.8.6 supported; the online version of the manual will now state the current supported versions; Fix an error in OWMWeatherController that could cause it to stop updating; Unify the approach to entity filtering on all hub interface classes (controllers); this works for device entities only; it may be extended to other entities later; Improve error detail in messages for EzloController during auth phase; Add isRuleSet() and isRuleEnabled() functions to expressions extensions; Implement set action for lock and passage capabilities (makes them more easily scriptable in some cases); Fix a place in the UI where 24-hour time was not being displayed.

With build 25328, if you copy a global reaction, a new reaction does not appear in the UI unless you do a refresh. I recall this used to work without needing this page refresh? Anyway, only a minor nuisance.

Difficulty defining repeating annual period
R
I have tried numerous ways to define a recurring annual period, for example from December 15 to January 15. No matter which method I try - after and before, between, after and/not after, Reactor reports "waiting for invalid date, invalid date. Some constructs also seem to cause Reactor to hang, timeout and restart. For example "before January 15 is evaluated as true, but reports "waiting for invalid date, invalid date". Does anyone have a tried and true method to define a recurring annual period? I think the "between" that I used successfully in the past may have broken with one of the updates.

Need help with sequence
T
Good evening all, For about the past week or so, I've been having problems with a specific rule in my home automation that controls when my home goes from an Away mode to Home mode. One of the conditions it checked for was my alarm panel, when it changed from Armed Away to Disarmed. There seems to have been a firmware update on the panel that added an intermittent step of "pending", and I can't say for certain it happens 100% of the time. Is there a way to write a condition that so it changes from one condition, to the next, and then another condition? As in, Home alarm changes from armed_away to pending to disarmed. Thanks.

Possible feature request?
CatmanV2C
No idea how easy this would be. During my migration away from Z-wave I've been replacing the Z-wave devices with Sonoff which has broken some of my automations. Any chance of a 'Test Reaction' function to call out which ones are broken because an entity no longer exists? Without actually running the reaction? Or does this exist already and I'm just not aware of how to do it? Obviously I can see entities that are no longer available, but not quite what I'm looking for. I guess it's something of an edge case so no huge issue. TIA! C

    I just read on the last MSR update that we need to update node.js. I just checked and on my Linux Debian machine its version 16.17.0.

    I then at the terminal ran this command but it says I already have the latest version of node.js which doesn't seem right.

    sudo apt-get install nodejs
    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    nodejs is already the newest version (16.17.0-deb-1nodesource1).
    0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
    
    

    Any tips?

    Thanks

    EDIT:

    I ran these commands instead to update all packages.

    sudo apt update

    then

    sudo apt upgrade

    I then did a node -v and now its version 16.20.2

    However the announcement says "all nodejs versions earlier than 18 are now end-of-life".

    EDIT2:

    I then tried these commands:

    npm install -g n

    n latest

    Now a node -v says its version 21.4.0

    However after restarting MSR I still get this alert error:

      Looks like it changed the path of the node installation? Maybe MSR is still looking at the old path?
      This was from the terminal output:

       installing : node-v21.4.0
             mkdir : /usr/local/n/versions/node/21.4.0
             fetch : https://nodejs.org/dist/v21.4.0/node-v21.4.0-linux-x64.tar.xz
           copying : node/21.4.0
         installed : v21.4.0 (with npm 10.2.4)
      
      Note: the node command changed location and the old location may be remembered in your current shell.
               old : /usr/bin/node
               new : /usr/local/bin/node
      If "node --version" shows the old version then start a new shell, or reset the location hash with:
      hash -r  (for bash, zsh, ash, dash, and ksh)
      rehash   (for csh and tcsh)
      
      

      There is a file called "node" under both usr/bin and usr/local/bin directories, I can see these using WinSCP to look at the file structure.

      This was also in the terminal before the above:

       npm install -g n

          So i ran into almost the exact same issue and this is how I managed to update NodeJS. Instead of running sudo apt update and sudo apt upgrade I followed the install instructions on NodeJS Github.

          To make Reactor happy I copied the path the old nodejs file was in and in my case it was /home/arman/.local/lib/nodejs I believe yours looks like it should be the same. Before doing anything copy and delete the NodeJS folder and put it somewhere where you can access it again if you run into any issues. Following the steps replace anywhere where it says /usr/local/lib/nodejs with /home/{user}/.local/lib/nodejs. This is where I have a band-aid repair to get Reactor back up and working. I renamed the new folder in the /home/{user}/.local/lib/nodejs directory from the new version of NodeJS to the previous version. In my case it I changed it from node-v20.10.0-linux-armv7l to node-v16.15.1-linux-armv7l. Then Reactor was happy and no error saying I need to update Node. This is a temporary fix however.

          I am no Linux expert so please take my advice with caution lol!

            I had same issue and went back to the MSR manual where it noted if you didn't have a system install of nodejs MSR would do a local one for just it's user.

            I reran the opening steps from the manual and it updated to 18.x just fine.

              Thanks for the replies and tips.

              In the end after more Googling for my Debian Buster install this seems to have fixed it for me.

              I removed the new /usr/local/bin/node directory that got installed the other day.

              rm /usr/local/bin/node

              Then running the command "which node" the path was back to the old path of /usr/bin/node and "node -v" was showing the old version again of 16.20.2

              I then found these commands on Google and tried them:

              curl -fsSL https://deb.nodesource.com/setup_current.x | sudo -E bash -

              sudo apt-get install -y nodejs

              This seems to have upgraded the 16.20.2 version with a newer version, I saw this line in the terminal output

              Unpacking nodejs (20.5.1-deb-1nodesource1) over (16.20.2-deb-1nodesource1)

              Now when I do a node -v it says its version 20.5.1 and the alert message in MSR has now gone.

              "which node" still says the path is the original path of /usr/bin/node also.

              I have no idea if this was the correct way to do it but I think it has worked.

                I think we all have a similar problem. My step-by-step was as follows.

                sudo apt remove nodejs
                sudo apt remove npm
                sudo apt autoremove
                
                sudo apt purge nodejs
                sudo apt purge npm
                sudo apt autoremove
                
                sudo apt-get update
                sudo apt-get install -y ca-certificates curl gnupg
                sudo mkdir -p /etc/apt/keyrings
                curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg

                sudo apt-get install nodejs -y
                

                Now comes the very rare story, if I'm not as toot I get this information.

                node -v
                v20.10.0
                
                npm -v
                10.2.3
                
                

                PERFECT!!

                But after the su --, I become root and the version that comes is 12? and then I really don't understand. I did the tasks like this, as root and without root, in the same way.

                If any expert can help me understand this madness.

                Thanks.

                  The PATH environment variable for root is different from that of regular users. You can echo $PATH in each to see the differences. The path is processed in order, first come first served.

                    Well, I've just solved my problem, whether it's the right way or not I can't say, but it was brute force, I used the "which node" command, I located all the directories regardless of version and deleted them (rm node -r), this while being root. Then I did a fresh install 🙂 solved.

                      @wmarcolin That may have worked, but it's not strictly right and may lead to complications down the road, like versions of node and npm being out of sync.

                      NOTE: Some of this can be used as instructions. Read all carefully and understand what you are doing before you actually do anything. If you don't understand, ask first, understand first, then proceed (always with caution and careful attention to detail).

                      Generally speaking, it's not a good idea to tamper with the system-installed version of any utility if there is one. If you use a command like apt-get install node or similar and it puts a version into /usr/bin, that's where you should leave it, and never change it (unless apt or yum does). That's because the system packages are versioned together as a group, so other system utilities may have dependencies on that system-blessed version of the package and its associated utilities and libraries.

                      When you want a newer version of node, the generally-recommended way is to do a custom install, which can be done either to a user-specific directory (so that one user can have a private version), or system-wide in a location under /usr/local (usually installed in /usr/local/lib with symbolic links from /usr/local/bin for the executables).

                      Either way, the version of node that runs is the first one encountered in the PATH environment then in effect.

                      Reactor has been tested with all three common install methods: the native system packages, when up to date; a /usr/local install; and a user-directory-specific install. All work fine.

                      Taking the structure of one of my RPis running Raspbian Buster (Debian 10), but should apply to almost any Linux-based platform...

                      The default system install puts a node and npm in /usr/bin:

                      pi@rpi4-2:~ $ ls -l /usr/bin/node
                      -rwxr-xr-x 1 root root 5536 Feb 24  2023 /usr/bin/node
                      pi@rpi4-2:~ $ /usr/bin/node -v
                      v10.24.0
                      pi@rpi4-2:~ $
                      

                      Notice that when I ran the node command, I ran it with a full path (i.e. as /usr/bin/node and not just typing node). That's because I have a newer version of node installed in /usr/local that is configured to take precedence. And also notice how old that system-installed package is!

                      My later-version installation in /usr/local/lib (specifically) looks like this:

                      pi@rpi4-2:~ $ ls -l /usr/local/lib/
                      total 12

                      total 42112

                      pi@rpi4-2:~ $
                      

                      You can see here, I have a nodejs subdirectory in /usr/local/lib. In here, I've got the downloaded archives for two versions (an 18 and a 20), of which the 18 is currently unpacked in the directory node-v18.18.2-linux-armv7l. That's a completely self-contained package for nodejs, ready to run. All that was needed was to configure it to run.

                      Configuring this version of node to run took two additional steps. First, I went to /usr/local/bin, and symbolically linked the executables from the v18 package, like this (notice I'm doing this step as root) :

                      root@rpi4-2:~# cd /usr/local/bin
                      root@rpi4-2:/usr/local/bin# ln -sf /usr/local/lib/nodejs/node-v18.18.2-linux-armv7l/bin/* .
                      root@rpi4-2:/usr/local/bin# ls -l
                      total 4
                      lrwxrwxrwx 1 root root 61 Dec 11 12:30 corepack -> /usr/local/lib/nodejs/node-v18.18.2-linux-armv7l/bin/corepack
                      lrwxrwxrwx 1 root root 57 Dec 11 12:30 node -> /usr/local/lib/nodejs/node-v18.18.2-linux-armv7l/bin/node
                      lrwxrwxrwx 1 root root 56 Dec 11 12:30 npm -> /usr/local/lib/nodejs/node-v18.18.2-linux-armv7l/bin/npm
                      lrwxrwxrwx 1 root root 56 Dec 11 12:30 npx -> /usr/local/lib/nodejs/node-v18.18.2-linux-armv7l/bin/npx
                      root@rpi4-2:/usr/local/bin#
                      

                      The first command changes directory to /usr/local/bin, and the second symbolically links all files in the package's bin subdirectory to the current directory (which is our /usr/local/bin). The ls command shows the result of that operation. So you can see, the executable in /usr/local/bin/node isn't an executable at all, it's a symbolic link to the executable in the package directory. Same with the other nodejs commands in the package.

                      The last step is to get that executable in /usr/local/bin/node to take precedence over the older version in the system install (i.e. the one in /usr/bin/node). All that is required to do this is that /usr/local/bin/node be seen by the shell before /usr/bin/node. This is done by making sure /usr/local/bin comes before /usr/bin in the PATH environment variable. On most systems, this is already the default case -- it's set up that way and you don't need to do anything. On some systems, you may need to add it. This can be done by adding a snippet like the following to the end of /etc/profile (to make it a system-wide change):

                      PATH=/usr/local/bin:$PATH
                      export PATH
                      

                      This puts /usr/local/bin at the head of the PATH. Again, this usually isn't necessary, because /usr/local/bin is already early in the path on most systems by default. You can check your path by doing echo $PATH as I said before. If you do end up having to make this change, you'll need to log out and log back in to make it take effect. And, any time you edit anything in /etc, it's a good idea to make a backup copy of the unmodified file first, in case you goof something up and need to revert (cp /etc/profile /etc/profile.old is sufficient).

                      If you're installing a per-user version of nodejs, the structure is fairly similar, but rather than unpacking the nodejs archive into /usr/local/lib/nodejs, you unpack it into ~/.local/lib/nodejs/ (remember ~ is a synonym for $HOME and means the current user's home directory path) with the same structure that I showed above for /usr/local/.... Notice we are not root here!

                      # For user-local install, all work is done NOT as root. Here, I'm just "pi"

                      Reading these steps, the first five commands create the structure of the .local subdirectory needed, with subdirectories bin, lib and lib/nodejs within just like we would have in /usr/local. At this point, the current directory is ~/.local/lib/nodejs, and the wget command is used to download the nodejs package we want (change version and architecture to what you need if you are actually doing this). Then we un-tar it right where we are. After un-taring it, we change directory to our own ~/.local/bin and make the symbolic links for the nodejs commands in the package directory, just like we did for /usr/local.

                      The last step is again, and this may be default, is making sure this user's PATH environment variable includes our new local ~/.local/bin directory. Check it with echo $PATH to see if you need to make the addition. If so, the easiest way to do that is to add the following snipped to ~/.profile, which is the per-user equivalent to /etc/profile (the per-user script runs after the /etc script at login) to set up the shell environment. My Raspbian Buster (Debian 10) systems seem to have this done already as a default, so before making any changes, check your PATH and/or ~/.profile.

                      PATH=$HOME/.local/bin:$PATH
                      export PATH
                      

                      Log out and back in, and then a which node should give you ~/.local/bin/node (or /home/username/.local/bin/node). You then have a per-user custom version of nodejs that doesn't interfere with any system versions.

                      Now, for running Reactor as a service, you need to be aware of where you are running it, and as who. It's generally not recommended to run Reactor as root on any bare-metal system (it runs as root on docker containers, but that's OK because the container is a constrained virtual environment). So when setting up, for example, your systemd profile for Reactor, you would want to make sure the profile contains both a User directory to set the correct (non-root) user for the running process, and a full path to the correct node executable in ExecStart (e.g. ExecStart=/home/pi/.local/bin/node app -p).

                      One last point: nodejs is so well-written that its entire dependencies exist entirely within its package structure, so whatever node command runs knows automatically where to find everything else it needs — you don't need to set a bunch of other environment variables to make each version work properly. That means you could, for example, run /usr/bin/node and see a perfectly working v10.24.0 as I showed above, or /usr/local/bin/node and get a perfectly-working v18.18.2 if that's what is installed there, and ~/.local/bin/node to get a fine v20.9.0 environment if that's what's installed there. Not all packages are this tight, and we can be grateful for it.

                      Tip: don't stop at which node when you are trying to figure out what is running. nodejs itself makes extensive use of symbolic links, so doing which node is only the tip of the iceberg. You need to then do ls -l /that-path and see if it's a symbolic link to somewhere else, as I showed in the output above. Keep following those links until you find the "real deal" and you'll find which version is actually running and where it actually lives.

                      I hope some of this clarifies how nodejs is installed, and highlights how you can actually have multiple versions of it installed on the system and they co-exist quite well, you just have to be careful.

                        @toggledbits fabulous post, there. Thanks. 18.19.0 in /usr/local/bin for Reactor and, apparently working fine 🙂

                        Any particular reason not to go to 21?

                          Yes! Only even-numbered versions of nodejs are LTS (long-term support). For the longest life of the system between upgrades like this, use the LTS versions only. That's why I recommend 18 and 20.

                          Here's their release and support calendar: https://nodejs.github.io/nodejs.dev/en/about/releases/

                          Notice that 21 will be EOL far sooner than either 18 or 20.

                              @wmarcolin That may have worked, but it's not strictly right and may lead to complications down the road, like versions of node and npm being out of sync.

                              NOTE: Some of this can be used as instructions. Read all carefully and understand what you are doing before you actually do anything. If you don't understand, ask first, understand first, then proceed (always with caution and careful attention to detail).

                              Generally speaking, it's not a good idea to tamper with the system-installed version of any utility if there is one. If you use a command like apt-get install node or similar and it puts a version into /usr/bin, that's where you should leave it, and never change it (unless apt or yum does). That's because the system packages are versioned together as a group, so other system utilities may have dependencies on that system-blessed version of the package and its associated utilities and libraries.

                              When you want a newer version of node, the generally-recommended way is to do a custom install, which can be done either to a user-specific directory (so that one user can have a private version), or system-wide in a location under /usr/local (usually installed in /usr/local/lib with symbolic links from /usr/local/bin for the executables).

                              Either way, the version of node that runs is the first one encountered in the PATH environment then in effect.

                              Reactor has been tested with all three common install methods: the native system packages, when up to date; a /usr/local install; and a user-directory-specific install. All work fine.

                              Taking the structure of one of my RPis running Raspbian Buster (Debian 10), but should apply to almost any Linux-based platform...

                              The default system install puts a node and npm in /usr/bin:

                              pi@rpi4-2:~ $ ls -l /usr/bin/node
                              -rwxr-xr-x 1 root root 5536 Feb 24  2023 /usr/bin/node
                              pi@rpi4-2:~ $ /usr/bin/node -v
                              v10.24.0
                              pi@rpi4-2:~ $
                              

                              Notice that when I ran the node command, I ran it with a full path (i.e. as /usr/bin/node and not just typing node). That's because I have a newer version of node installed in /usr/local that is configured to take precedence. And also notice how old that system-installed package is!

                              My later-version installation in /usr/local/lib (specifically) looks like this:

                              pi@rpi4-2:~ $ ls -l /usr/local/lib/
                              total 12

                              pi@rpi4-2:~ $
                              

                              You can see here, I have a nodejs subdirectory in /usr/local/lib. In here, I've got the downloaded archives for two versions (an 18 and a 20), of which the 18 is currently unpacked in the directory node-v18.18.2-linux-armv7l. That's a completely self-contained package for nodejs, ready to run. All that was needed was to configure it to run.

                              Configuring this version of node to run took two additional steps. First, I went to /usr/local/bin, and symbolically linked the executables from the v18 package, like this (notice I'm doing this step as root) :

                              root@rpi4-2:~# cd /usr/local/bin
                              root@rpi4-2:/usr/local/bin# ln -sf /usr/local/lib/nodejs/node-v18.18.2-linux-armv7l/bin/* .
                              root@rpi4-2:/usr/local/bin# ls -l
                              total 4
                              lrwxrwxrwx 1 root root 61 Dec 11 12:30 corepack -> /usr/local/lib/nodejs/node-v18.18.2-linux-armv7l/bin/corepack
                              lrwxrwxrwx 1 root root 57 Dec 11 12:30 node -> /usr/local/lib/nodejs/node-v18.18.2-linux-armv7l/bin/node
                              lrwxrwxrwx 1 root root 56 Dec 11 12:30 npm -> /usr/local/lib/nodejs/node-v18.18.2-linux-armv7l/bin/npm
                              lrwxrwxrwx 1 root root 56 Dec 11 12:30 npx -> /usr/local/lib/nodejs/node-v18.18.2-linux-armv7l/bin/npx
                              root@rpi4-2:/usr/local/bin#
                              

                              The first command changes directory to /usr/local/bin, and the second symbolically links all files in the package's bin subdirectory to the current directory (which is our /usr/local/bin). The ls command shows the result of that operation. So you can see, the executable in /usr/local/bin/node isn't an executable at all, it's a symbolic link to the executable in the package directory. Same with the other nodejs commands in the package.

                              The last step is to get that executable in /usr/local/bin/node to take precedence over the older version in the system install (i.e. the one in /usr/bin/node). All that is required to do this is that /usr/local/bin/node be seen by the shell before /usr/bin/node. This is done by making sure /usr/local/bin comes before /usr/bin in the PATH environment variable. On most systems, this is already the default case -- it's set up that way and you don't need to do anything. On some systems, you may need to add it. This can be done by adding a snippet like the following to the end of /etc/profile (to make it a system-wide change):

                              PATH=/usr/local/bin:$PATH
                              export PATH
                              

                              This puts /usr/local/bin at the head of the PATH. Again, this usually isn't necessary, because /usr/local/bin is already early in the path on most systems by default. You can check your path by doing echo $PATH as I said before. If you do end up having to make this change, you'll need to log out and log back in to make it take effect. And, any time you edit anything in /etc, it's a good idea to make a backup copy of the unmodified file first, in case you goof something up and need to revert (cp /etc/profile /etc/profile.old is sufficient).

                              If you're installing a per-user version of nodejs, the structure is fairly similar, but rather than unpacking the nodejs archive into /usr/local/lib/nodejs, you unpack it into ~/.local/lib/nodejs/ (remember ~ is a synonym for $HOME and means the current user's home directory path) with the same structure that I showed above for /usr/local/.... Notice we are not root here!

                              # For user-local install, all work is done NOT as root. Here, I'm just "pi"
                              pi@rpi4-2:~ $ mkdir -p ~/.local/lib
                              pi@rpi4-2:~ $ mkdir -p ~/.local/bin

                              Reading these steps, the first five commands create the structure of the .local subdirectory needed, with subdirectories bin, lib and lib/nodejs within just like we would have in /usr/local. At this point, the current directory is ~/.local/lib/nodejs, and the wget command is used to download the nodejs package we want (change version and architecture to what you need if you are actually doing this). Then we un-tar it right where we are. After un-taring it, we change directory to our own ~/.local/bin and make the symbolic links for the nodejs commands in the package directory, just like we did for /usr/local.

                              The last step is again, and this may be default, is making sure this user's PATH environment variable includes our new local ~/.local/bin directory. Check it with echo $PATH to see if you need to make the addition. If so, the easiest way to do that is to add the following snipped to ~/.profile, which is the per-user equivalent to /etc/profile (the per-user script runs after the /etc script at login) to set up the shell environment. My Raspbian Buster (Debian 10) systems seem to have this done already as a default, so before making any changes, check your PATH and/or ~/.profile.

                              PATH=$HOME/.local/bin:$PATH
                              export PATH
                              

                              Log out and back in, and then a which node should give you ~/.local/bin/node (or /home/username/.local/bin/node). You then have a per-user custom version of nodejs that doesn't interfere with any system versions.

                              Now, for running Reactor as a service, you need to be aware of where you are running it, and as who. It's generally not recommended to run Reactor as root on any bare-metal system (it runs as root on docker containers, but that's OK because the container is a constrained virtual environment). So when setting up, for example, your systemd profile for Reactor, you would want to make sure the profile contains both a User directory to set the correct (non-root) user for the running process, and a full path to the correct node executable in ExecStart (e.g. ExecStart=/home/pi/.local/bin/node app -p).

                              One last point: nodejs is so well-written that its entire dependencies exist entirely within its package structure, so whatever node command runs knows automatically where to find everything else it needs — you don't need to set a bunch of other environment variables to make each version work properly. That means you could, for example, run /usr/bin/node and see a perfectly working v10.24.0 as I showed above, or /usr/local/bin/node and get a perfectly-working v18.18.2 if that's what is installed there, and ~/.local/bin/node to get a fine v20.9.0 environment if that's what's installed there. Not all packages are this tight, and we can be grateful for it.

                              Tip: don't stop at which node when you are trying to figure out what is running. nodejs itself makes extensive use of symbolic links, so doing which node is only the tip of the iceberg. You need to then do ls -l /that-path and see if it's a symbolic link to somewhere else, as I showed in the output above. Keep following those links until you find the "real deal" and you'll find which version is actually running and where it actually lives.

                              I hope some of this clarifies how nodejs is installed, and highlights how you can actually have multiple versions of it installed on the system and they co-exist quite well, you just have to be careful.
