Domoticz crash after installing the zigbee2mqtt plugin

[dolf182]

I downloaded the latest domoticz plugin version 2022.1 Installed the latest mqtt installed the latest mqtt2zigbee. Connection to my zigbee receiver works fine. Domoticz works fine. After installing the plugin and restarting domoticz every is just fine. When i add the zigbee device using this plugin domoticz won't start up again. After removing the zigbee2mqtt plugin folder domoticz works again. Tried the release of domoticz and the beta version nothing seems to help.

Has anybody else this issue?

Same issue with crashing. Python 3.9 might cause it?

[stas-demydiuk]

Yes, most likely that's the issue as there were several messages that Domoticz doesn't work well with Python 3.9. See #689

Tried serveral things after putting the log here.

• Not using the installer but building domoticz on the raspberry pi. did not fix the issue. End of 2021 there were some issues with the installer causing several issues.

Changed the system default python to 3.8 but domoticz is still using 3.9. I have to look into this how to set the domoticz default python.

Apperenty the python version seems to cause issues when domoticz is loading plugins.

It seems to be not related to this plugin. Thank you for your fast response.

Got it working for now...

The issue is raspberry pi bullseye

• First we have to make an image with buster lite or desktop it doesn't matter.
• install the mosquitto mqtt broker: https://randomnerdtutorials.com/how-to-install-mosquitto-broker-on-raspberry-pi/
• install zigbee2mqtt: https://www.zigbee2mqtt.io/guide/installation/01_linux.html
• install python 3.7 buster comes with 2.7: https://installvirtual.com/install-python-3-7-on-raspberry-pi/
• install the libpython : sudo apt-get install python3.7 libpython3.7 python3.7-dev -y
• install domoticz: https://www.domoticz.com/wiki/Raspberry_Pi -> curl -sSL install.domoticz.com | sudo bash
• restart the pi -> sudo reboot now
• get the plugin from this website: cd domoticz/plugins git clone https://github.com/stas-demydiuk/domoticz-zigbee2mqtt-plugin.git zigbee2mqtt
• restart domoticz -> sudo /etc/init.d/domoticz.sh restart
• add the hardware
• add the api_transport device in devices

if everything went ok you have working zigbee again on your pi.

Until the issues with bulleye aren't fixed this can be a solution for people struggling with the plugins

I think it is more an pyton 3.9 issue with domoticz. Let me know in the comments if not...

Kind Regards

Hi Arjan, Thank you for your feedbak I'll try your solution this evening. Thks

[dolf182]

Hello,

Just a short update

So i tried to install python 3.7 on bullseye. That works fine but domoticz is using the:

libpython and python dev for loading in the plugins.

the 3.7 versions are not availible anymore for bullseye.

removing the libpython3.9 and python3.9-dev and reinstall the version 3.8 of both versions will fix the crash issue.

The downside is you can add the plugin and the api_transport device. But the zigbee2mqtt page is not showing up

Hi Arjan, thanks a lot for you feedback. I've tried python 3.8 as well yesterday . same conclusion as yours... So it Works fine on Buster thank you again

Python support on Bullsye could be fixed in latest beta with commit https://github.com/domoticz/domoticz/commit/8f01ed77d5831090f34ad59d22ef1f7cd4d740f2 But try out in a beta environment first as it is early beta changes.

Please report issues in https://www.domoticz.com/forum/viewtopic.php?f=6&t=38086

This fixed the issue for me on bullseye
