Local expression in Rule does not evaluate as they used to do

[cw-kid]

Just checked my Raspberry Pi that is running the live version of MSR currently and that is node version 12.22.0

@cw-kid said in Issues installing MSR on Debian 10 Linux:

So just need to figure out how to make MSR auto start on boot under Debian 10 Buster.

Here's a sample service configuration for systemd. You would modify and place this file in (typically) /etc/systemd/system/reactor.service.

[Unit]
Description=Multi System Reactor
After=network.target

[Service]
Type=simple
User=patrick
WorkingDirectory=/home/patrick/Documents/reactor
ExecStart=/usr/local/bin/node app -p
Restart=on-failure
RestartSec=5s

[Install]
WantedBy=multi-user.target

The key things you need to modify are the User value (do not run Reactor as root), the WorkingDirectory (path to the Reactor install directory), and ExecStart for the correct path to your node executable.

Then run the following commands:

sudo systemctl daemon-reload    # tells systemd the config has changed
sudo systemctl enable reactor   # tells systemd to start the service at boot
sudo systemctl start reactor    # tells systemd to start the service now

Also since you've just installed/upgraded nodejs, don't forget to run npm i --no-save in your Reactor install directory before starting Reactor.

@toggledbits said in Issues installing MSR on Debian 10 Linux:

To avoid confusion, remove the nodejs and npm packages you installed before downloading and installing.

OK thanks that's helpful about running it as a service, but I am not that far along yet I don't think.

Now need to uninstall node js and the npm packages and then install the 14.x node js version etc.

Which I am not sure how to uninstall things yet.

[cw-kid]

OK I think I have uninstalled everything using these commands:

apt remove nodejs

apt autoremove

I've downloaded the x86 64bit Linux version of node js and I am looking at installing that one instead now.

[toggledbits]

It looks like the PPA link you gave recommends adding a package repository and installing them via apt, so uninstall should just be:

sudo apt remove nodejs npm

Those PPA instructions also tell you how to get the version you want.

[cw-kid]

@toggledbits said in Issues installing MSR on Debian 10 Linux:

sudo apt remove nodejs npm

Bit late to run that command:

 apt remove nodejs npm
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package 'npm' is not installed, so not removed
Package 'nodejs' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I think the commands I ran earlier have removed things but I still see a .npm folder in my home folder.

I am working out now how to install the later 14.x version of node js.

EDIT:

I installed again using the PPA method and just changed the curl command to use the 14.x

curl -sL https://deb.nodesource.com/setup_14.x -o nodesource_setup.sh

I now have node version 14.17.0 installed.

Don't forget to complete the Reactor install instructions here: https://reactor.toggledbits.com/docs/Installation/#new-install-linux-various-bare-metal-without-docker

[cw-kid]

@toggledbits

OK making some progress slowly. I now have MSR up and running automatically after a system reboot.

And I am on node js version 14.17.0

Now to copy everything from my Rpi installation to the new HP Thin Client installation to get all my rules moved over.

I assume I can just copy the entire reactor folder from one machine to the other.

[toggledbits]

You just need config and storage subfolders. It won't hurt to copy everything, but it's overkill.

[cw-kid]

OK many thanks.

Just looking at setting a static LAN IP first on the new HP thin client box.

[toggledbits]

Probably a good idea to make sure you have NTP running on the box as well (network time).

[cw-kid]

@toggledbits said in Issues installing MSR on Debian 10 Linux:

NTP running on the box

OK I'll have to look in to how to do that then also.

[rafale77]

@cw-kid, yeah it takes a little googling to set up and brand new debian OS but I am sure you will get there. I went through the same thing setting up my T640. Debian takes a little bit more work than ubuntu which has a lot of these setup by default.

[cw-kid]

@toggledbits

I'm reading this article about Debian and time here.

The date and time is currently set correctly:

"By default, Debian 10 runs the standard ntpd server to keep your system time synchronized with a pool of external time servers. We can check that it’s running with the systemctl command:"

sudo systemctl status ntp

When I run this command in Putty it says:

Unit ntp.service could not be found.

It goes on to say "To get more information about the status of ntpd we can use the ntpq command:"

ntpq -p

I get the response:

-bash: ntpq: command not found

So maybe its not currently installed on my installation.

its only a 16GB SSD in the HP Thin Client, so I don't have a desktop environment installed only SSH server etc.

I will look at installing this ntpd service next.

EDIT:

Ran this command to install it:

apt-get install ntp

Now the above commands are working.

Hi, well I bought the HP T520 Thin Client because of what you said to me previously. It was cheap enough from eBay.

I had some issues with the power supply however as it didn't come with one.
I did have a spare suitably spec'd laptop power supply, but it had the wrong DC connector plug on the end of it.

So I ordered the correct "DC Tip 7.4x5.0mm Power Plug Socket Connector" off eBay and cut the other one off and soldered the new one on.

However the HP Thin Client was not turning on, no power nothing at all and totally dead.

I then read that you have to use a genuine HP power supply, as they have some kind of checking so that the thin clients won't power on if you are using a 3rd party power supply.

Corporate Greed !

I then found an article about hacking the unit and soldering in a 240K resister on the back of the power input jack and I did this today and amazingly it worked and the thin client powered on.

One thing I can't figure out how to do yet is to update the BIOS without having one of their supported OS installed.

[rafale77]

@cw-kid

I don't have this exact model but... my HP desktops all have the ability to update the BIOS from within the UEFI BIOS. Have you tried that? Sorry for the song and dance on the power supply. I never encountered this since I always got power bricks with the ones I bought and I actually have spare power supplies... Great soldering job though!

[cw-kid]

@rafale77

There is an option in the BIOS menu to update / flash the BIOS but when I click OK on it, it says:

"Can not find bios update interface"

I've not really looked in to it properly yet as I was keen to get MSR up and running first.

From the quick Google searches I did, most suggested you need to have one of the HP supported operating systems installed to be able to update the BIOS.

But there must be some work around some how. I need to read in to it more.

[cw-kid]

@toggledbits I copied over the storage and config folder contents from the Rpi to the HP Thin Client and then restarted MSR on the thin client.

I did edit the base URL in the Reactor.yaml file.

I've stopped the MSR service on the Rpi so now the thin client is the only one running..

None of my scheduled rulesets based around sunset have run their actions this evening for some reason.

The time shown in the top of the MSR Web GUI is the correct time.

So seems I need to look into this further.

There is another schedule up coming, the garden lights should turn on 20 minutes after sunset, that is in about 20 minutes time from now, so will see if that happens?

EDIT:

These are the before sunset rules that the other rules reference in their triggers.

20 and 40 minutes before sunset, not sure why both say true as of the same time at 20:48pm.

The after sunset 20 minutes rule says:

waiting for 21:21:00

Its now 21:25pm and my garden lights have NOT turned on, so something not right here.

This is the summary card for the rule that turns on the garden lights:

[cw-kid]

Not sure which rule this is, but I am seeing several errors in the log like these:

Think something may have gone wrong with copying over the stuff from the Pi.

This is that folder in WinSCP on the HP Thin Client.

I installed MSR as a none root user aka as my own username name. But these rule set files most are saying root as the owner.

I was logged in to WinSCP as root user when I did the copy so maybe that is why.

If I try logging in to WinSCP as my username instead of root and then doing the copy again from the Pi to the Thin Client it doesn't work and I don't seem to have the permissions to do it.

If instead I try to change the group and owner of a file from root to my username I can't do that either:

So I am stuck now and don't know what to do.....

OK I logged back in to WinSCP as root and now I can change all the files their group and owner from root to my own user name. I have done that now for all of them.

So hopefully that fixes the problem? Will have to wait for later schedules to happen later this evening to see.

[cw-kid]

A scheduled rule set just ran actually and turned on the RGBW light strip in the kitchen, so think it's working now.
