I have a case where I'm trying to send a MQTT message similar to the example below:
Topic: pool/set { "command": 4, "value": 1, "time": 0, "interval": 0 }But I need to set "value" so that it is an integer between 20-30. I thought I could use "dimming" capability here, but there's probably a better way. @therealdb ?
(Using userauth-24120-7745fb8d build in Docker)
There's a filtering capability for entities in reactor.yaml, but I have a case where I don't want to filter an entity altogether, but would like to "throttle" it, as this sensor updates every 1-2 seconds (and therefore unnecessarily takes database space).
Sensor data comes through home assistant, and seems that there's no way to control update interval at that end.
So I'm asking if plugin configuration could support limiting/throttling updates for certain entities?
I need a handful of victims volunteers to help test previews of the next build of Reactor. A long-standing request was for "a simple login mechanism," but in practice, adding user authentication and competent access control turned out to be a pretty big project with a lot of big changes on both server and client sides. It's a bit more than I'm comfortable testing myself and springing out to everyone at once, so I'd like to work with a small group to put it through "sea trials."
Major changes/features include:
User authentication with hashed password storage; User group configuration with application restriction (admin, dashboard, API); Detailed control over API access, with user- and token-based authentication/authorization; Improvements to the HTTPS service; Improvements to UI coordination with the core for Rules and Reactions.If this sounds like something you'd like to help with, drop me a reply here in this thread or privately.
Good morning,
Hopefully this is a simple request. I believe the title should be self explanatory, but just in case, I'll elaborate.
On the status tab, we all get alerts if a device state has changed (i.e., been removed). This is great, but when I go into the entities tab, I have to either type the name (or a portion thereof) of the device that has been removed, or I need to scroll all the way through my list of devices. This is infrequent, however, yesterday I replaced a failed device in my HAAS environment. It was a Z-Wave switch that is added using the Smart Scan QR code, which normally makes it pretty easy. However, some devices don't get fully added the first time around, so it'll add multiple entries into HAAS until it get's the S2 authentication correct and the device fully included. It did this to me yesterday, and I had to delete the incomplete device from my installation. MSR still saw the entities of that failed/incomplete switch entity, and I was left with 8 alerts and entities that I needed to removed.
It's not a huge problem, but this example was just one switch. If I were to add replace multiple devices at once, this could be a bit more annoying to remove. It would be helpful to be able to filter by removed entities, so I can find them all quickly and delete them. Continuing that train of thought, it would also be useful to have check boxes next to those lines, and perhaps do a select all type of thing so they could be deleted in one mouse click.
@toggledbits I have finally finished up the SSL using Let's Encrypt and am getting this from my local browser:

I know you said in the docs that using a self-signed could lead to this but this is LE.
Hi @toggledbits,
I don't know if I'm the only one, so I'm reporting here first instead of opening a bug.
Basically, with the latest 2-3 updates of Reactor and MQTTController, after a restart previous statuses are lost (for both Virtual and MQTT entities), until they're restored.
It's particularly annoying for Virtual Entities, because I have to set them all over again (I've coded some defaults at startup if the values are empty, but sometimes these are not the correct values before the update).
Not easy to reproduce, and logs are gone, but the first time I tought it was me hallucinating, the second one didn't bother too much, after the third I realized it's something not coming from me.
the behavior could be seen in this screenshot:
1c007fc2-4dbc-4476-8dca-e5aa111e4642-image.png
Any hint is appreciated.
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.I'm slowly migrating all my stuff to MQTT under MSR, so I have a central place to integrate everything (and, in a not-so-distant future, to remove virtual devices from my Vera and leave it running zwave only).
Anyway, here's my reactor-mqtt-contrib package:
![](https://github.com/fluidicon.png)
Contrib MQTT templates for Reactor. Contribute to dbochicchio/reactor-mqtt-contrib development by creating an account on GitHub.
Simply download yaml files (everything or just the ones you need) and you're good to go.
I have mapped my most useful devices, but I'll add others soon. Feel free to ask for specific templates, since I've worked a lot in the last weeks to understand and operate them.
The templates are supporting both init and query, so you have always up-to-date devices at startup, and the ability to poll them. Online status is supported as well, so you can get disconnected devices with a simple expression.
Many-many thanks to @toggledbits for its dedication, support, and patience with me and my requests 🙂
Good morning,
So Home Assistant decided to change the default weather home format that I've been using for the past year and a half. I had two Global Expressions set up to pull the high and low temp forecast for the day. Now it's pulling null values.
094c9205-cc9e-4fcc-ac4f-1bf54acea299-image.png
In the dev tools, it now uses a new service (Weather. get forecasts), plural, where the old Weather.get forecast is depreciated and now longer functions.
8c7a1fcc-dd3f-4268-a0b7-29d542f86adc-image.png
It shows a templow field, and a temperature field, which I presume is the forecast high.
When I head back over to MSR, I'm having a hard time finding those values in the Entities tab.

MSR: latest-24057-e9add9f5
Hey Patrick, I recently have been noticing that MSR has been acting up ie. it's been needing restarts and has been slow. I began trouble shooting by looking at the logs and have noticed the following errors for a lot of entities. I thought maybe a simple reboot of RPi was needed and I kept seeing the same errors in the system logs. I am oddly enough not seeing these same errors in the MSR logs. Where things started getting weird is whenever I rebooted MSR it wouldn't come back online .I would have to restart the RPi then it would come back online. I just restarted MSR again to capture logs and it restarted fine, so I guess its good for now? I think this is more or so a corrupted SD card issue rather a MSR issue but well being troubleshooting from here. The SD card is about 1-2 years old.
Apologies if this post is everywhere, I cannot consistently recreate any oddities that are happening, that's what is leading me to believe my SD is going bad.
PS: If anyone knows how to diagnose a corrupt SD card please chime in.

This system has been running flawlessly year after year for the time changes twice a year literally since MSR came out so I was caught off-guard when this happened this morning.
Time in MSR browser is EST, time on RPi is local time (DST).

What am I missing here @toggledbits ?
Hi,
For the standard capabilities MSR sends both a value record and a units record to InfluxDB. The latter I would like not to send as they are not really any use for me and it will reduce the number of records send to my InfluxDB.
Is there a quick way to do this with a filter_entities line like: *>units?
Or do I have to update all capabilities to read like this:
power_sensor:
attributes:
value: true
Cheers Rene
I'm trying to replicate this
wallbox_set_number.PNG
into a MQTT entity where I could set a number with a min and max value.
I can't find a standard capability that fits or any documentation on local MQTT capabilities and the only post on the forum mentioning local MQTT capabilities is this post, is it even possible in current release?
My trial and error work in local_mqtt_capabilities.yaml isn't much to show as it's just a copy of mqtt_capabilities.yaml with changed names and then I got stuck.
Any guidance, examples, documentation, future feature request or denial would be much appreciated, thanks!

Hi guys,
I've recently bought a new Govee outdoor permanent lights set, and I love it. WAF is pretty high, and the product is good quality. I hope to never run lights in the front of the house.
This new addition has found me searching for something to control these lights, locally. Govee has officials remote and LAN APIs and Home Assistant has it supported, but some undocumented stuff that's integrated into an Homebridge plugin that seems very promising. Without this plugin, my playlist is orchestrated via the cloud and that makes zero sense.
In the past I got some inspiration from plugins running on other platforms and Homebridge seems one of the most active. I could map its devices via HomeKit-local on HA, but I've decommissioned Homebridge years ago when we settled to Alexa (and I want to stay simple), so I had an idea: why get inspiration and rewrite things, when you could write an Homebridge adapter that could load any Homebridge plugin and run them natively under Reactor (MSR)?
I'm not sure if that's viable or made any sense, so I'm posting here to get feedback, encouragement and your thoughts. Anyone could be potentially interested in such a thing?
Hi- looking for a hint in where to start. My goal is to set a PIN code in a zwave kwikset lock triggered in a rule.
The device isn’t exposing methods to help. The x-hass.call-service looks promising, but what would the service name be?
Plan b would be send the zwave controller a config command- I don’t see any way to explicitly send a command through JS Zwave in my environment.
Running reactor bare metal. JS Zwave is running as an add on inside HASS OS.
Any tips are appreciated.
Hey crew, I'm trying to use MSR to control the RGB values of a Z-Wave bulb in Home Assistant.
Problem I'm running into - I would like to use 'rgb_color.set' to control this, but it doesn't work, instead it always passes the values '255,255,255' to HA no matter what values I enter within MSR.
More notes and examples below - I'm wondering if this is a formatting issue that I'm missing? Thanks for any help!
NOTES FROM TROUBLESHOOTING:
'rgb_color.set_rgb' works successfully, which seems strange. You'd think they would both be affected I've tried a couple different formats, like adding quotes, adding/removing spaces between the RGB values, nothing has fixed it.EXAMPLES:
When I use 'rgb_color.set_rgb', the values successfully carry over to Home Assistant:

But when I use 'rgb_color.set', the values DO NOT successfully carry over to Home Assistant:

I’m running MSR in a docker container on my Synology Nas. The container is automatically updated using watchtower weekly.
It was working. Now, after the update, Reactor webpage is able to load, and all indications on the webpage suggests that it is working fine. However, the updated statuses from Home Assistant and Vera are not being detected.
The container logs show the following error

Noticed right away last night at closing time that the open/close had become inverted with the update to v23326.
It wasn't an awful bit of lift to change all Reactions to reflect the change but it was jarring initially when everything flipped.
Are there release notes on that version, @toggledbits ?
How to auto start on Rpi reboot ?
-
I would add
User=pi
at a minimum to the service section.I have concerns about the stop action. Investigating...
-
Thanks, I did miss the sudo for the nano command to create the file.
The path does look suspicious too in addition to @toggledbits input. There may be other specificities about raspbian I may be missing.
-
This is the contents of the msr.service file now
[Unit] Description=Multi System Reactor After=network.target [Service] User=pi Type=simple ExecStart=nohup /home/pi/Documents/reactor/app.sh Restart=on-failure RestartSec=5s [Install] WantedBy=multi-user.target
-
There are several things to indicate that the process is not ready for this at this point. Among them is that the nodejs installation done by the installer is local to the
pi
user. There are also issues with the home directory, and the search paths for modules and data relative to the current working directory vs the path of the application.Too soon. Not ready yet. Not going to fix it tonight. This is prelease software. It isn't mean to run like production software at this point.

Think I have it working now and MSR is auto starting after a reboot
I placed my msr.service file in this directory:
/home/pi/Documents/reactor
Using WinSCP, on the msr.service file properties, I made its Group and Owner to be pi rather than root.
This is the files contents:
[Unit] Description=Multi System Reactor After=network.target [Service] Type=simple ExecStart=nohup ./app.sh & WorkingDirectory=/home/pi/Documents/reactor Restart=on-failure RestartSec=5s [Install] WantedBy=multi-user.target
I then ran these commands in the terminal in Putty:
sudo systemctl enable /home/pi/Documents/reactor/msr.service
sudo systemctl start msr
And I can check its status with this command:
sudo systemctl status msr
It says its active and running.
If I reboot the Pi now after the reboot the MSR web page is then available and can be accessed.
-
Yeah, but running the shell script is not correct. You're basically having systemd do what the shell script is also doing (restarting when stopped), and it's going to cause problems. Your exec is also forking, so adding yet another layer of indirection that all but guarantees that systemd is going to be looking at the wrong process ID for what it thinks is a running Reactor. That could lead to problems stopping and restarting, and with the possible effect that an incorrect stop causes data loss.
-
You're not far off, really, but the devilish details require some internal knowledge of how Reactor starts and organizes itself, and it's made a bit more complicated by the necessity to locate things "off shore" for docker containers and make sure that stays working as well. There's a bit of a balancing act there. As I'm sure you know well, features are not strictly governed by their ability to be implemented; they are also very much a function of what it takes to support them. I'd rather there be an "official" way that I know people use, because if ten people do it their own way, I'll have ten different ways I need to figure out any time there's a problem.
-
Right now, all data is written when modified, but that may not always be the case, and there's a high likelihood it will be user-configurable, even.
One of the things designed in is that MSR is "crappy-storage-ready". @rafale77 can tell you at length about the merits and woes of various storage technologies, and an SD card in a Raspberry Pi is no exception (in fact, probably both a good example and a dire warning). MSR has a storage architecture for its data that allows "pluggable" storage disciplines, so you could, for example, choose a cached-with-delayed-write-back mechanism to reduce wear, and you could choose that for everything, or just states, or states and logs, etc. So in that case, as the system shuts down, it is necessary for the cache to write back any "dirty" (modified but unsaved as yet) data, or the modifications would be lost.
That said, you should be thinking about getting your Pi off an SD card if that's what you're running, if you intend to run it full-time with MSR and depend on it. There are only two types of SD cards: those that have failed, and those that are about to. I have my Pi running on a cheap 2.5" SSD, and it's also a good bit faster, although there is some alchemy to getting that working, and while it's much better than it was, it involves some pretty magical incantations still today and can be a bit angst-inducing.
-
Getting the firmware onto the Pi is a series of commands rarely used, so that's part of it. The other part is that your choice of interfaces is critical, as some are supported and some are not.
-
I had no problems with the interfaces, I guess I was lucky. I bought an ordinary SATA to USB3 cable and a standard Samsung 250G disc and plugged it in.
For the commands and if anyone is interested I used the following guide:
-
The guide is OK, but it contains two omissions that I think are pretty important for the average user:
- The first is the interface issue. Only certain interfaces work, and some definitely do not. I first purchased the Sabrent 3.0 to SSD model EC-SSHD. Doesn't work. Found in another guide (linked below) what does work. Thankfully, I had on hand a bigger 3.1 dual-drive powered USB 3.1 interface I use for doing backups and other evil deeds around the house, so I got that Frankensteined on until the working Sabrent 3.1 to SSD model EC-SS31 arrived. Notice the subtle but important difference. Sad but true.
- In Tom's Guide, in the SD Card Copier, the "New Partition UUIDs" checkbox must be off. They neglect to say this (it's shown off in the screen shot, but it's worth using words). If it's on, the boot will fail because the boot script and fstab will have the old IDs rather than the new. This is easily fixed if you know where and how to do it, but I think most users would find it frustrating if they don't realize what they've done.
Link with supported interfaces below. Don't use these older instructions, just use the list of supported devices it offers:

ha......truer words have never been spoken.
I just spent the last weekend trying to get a Pi4 booting from a SSD, followed every "how to" I could find and just can't get the bootloader to set to 0xf41, it remains stuck on 0xf14.
I might have to wait for a Pi5 to achieve my dream or borrow your magical incantations.....edit: now after reading the How to patrick refers to, it confuses me even more. It appears every time there is a FW update the goal posts change and Boot Order becomes something else. 0x1 , 0x4, OMG Maybe a Windows install is easier?
-
OK. Build 21074 has some necessary changes to support running as a system daemon under systemd on RPi4. As seen earlier in this thread, a service file is needed that needs to be placed in (typically)
/etc/systemd/system
. The easiest way to get the correct service file for your current install is to run thetools/rpi-install.sh
install script. On an installed system, it will not do much of anything, but it will create a file calledreactor.service
in thetools
subdirectory. From there:- Make sure any other Reactor processes are stopped (e.g.
pkill -QUIT node
) - Use
sudo cp tools/reactor.service /etc/systemd/system/
to copy the file to /etc; - Run
sudo systemctl daemon-reload
- If you want Reactor to start automatically at boot:
sudo systemctl enable reactor
- Start Reactor now:
sudo systemctl start reactor
You should now be able to see your log file recording the startup. You may also observe the log messages rolling in
/var/log/syslog
. The running Reactor instance will also leave areactor.pid
file in thereactor
install directory (it will remove it when it shuts down, so its absence is a good indication that it is not running under systemd). - Make sure any other Reactor processes are stopped (e.g.

@toggledbits said in How to auto start on Rpi reboot ?:
This is the reactor.service file it created:
# This file allows you to run your Reactor installation under systemd, # so it can be started at boot. Copy this file (as root or under sudo) # to /etc/systemd/system, and then run "systemctl daemon-reload". You # can then able Reactor to start at boot "systemctl enable reactor". # The usual systemctl subcommands can also be used to start, stop, and # restart reactor at will (e.g. "systemctl restart reactor"). [Unit] Description=Multi System Reactor After=network.target [Service] Type=simple User=pi WorkingDirectory=/home/pi/Documents/reactor ExecStart=/usr/bin/node app -p Restart=on-failure RestartSec=5s [Install] WantedBy=multi-user.target
I followed the rest of the instructions and I could see a reactor.pid file had been created and reactor was running again.
I then rebooted my Pi and after it rebooted MSR is running again.
So everything appears to have worked OK.
Thanks
