Domoticz systemd or python problem ?

Post by ricorico94 »

Hi,
I try to reinstall domoticz on a fresh Trixie installation on Raspberry ¨Pi 3B+. I don't use Docker (it looks complicated..).
I installed domoticz using the simple "sudo bash -c "$(curl -sSfL https://install.domoticz.com)" " command. This domoticz shows a version 2026.4.
I could import my previous domoticz database (which was 2024.4) and some features/sensors are working fine.
However, I face problem to add several python plugins and as I 'm investigating if it's problem due to Virtual environment, I notice that my domoticz doesn't seem using the systemd though I read on wiki that since Feb 26, it should be automatically started by systemd:

Code: Select all

pi@domoticz:~ $ sudo systemctl status domoticz
[sudo] Mot de passe de pi :
● domoticz.service - LSB: Home Automation System
     Loaded: loaded (/etc/init.d/domoticz.sh; generated)
     Active: active (running) since Sun 2026-10-25 18:59:08 CET; 17s ago
 Invocation: d0533f4822c14897b840aa3058f79fec
       Docs: man:systemd-sysv-generator(8)
    Process: 1061 ExecStart=/etc/init.d/domoticz.sh start (code=exited, status=0/SUCC>
      Tasks: 50 (limit: 806)
        CPU: 4.515s
     CGroup: /system.slice/domoticz.service
             └─1111 /home/pi/domoticz/domoticz -daemon -www 8080 -sslwww 443
Moreover, I can't find any domoticz.service file in /etc/systemd/system (whereas there is a domoticz.sh in /etc/init.d).
So this raises several questions (at least..):
- is it normal ? (domoticz version shows 2026.4..)
- how could I move to using the systemd ? where can I find the domoticz.service file ? (the linux wiki shows some "text/code", but I'm surprised that it shows "User=domoticz" whereas the underneath domticz.sh shows User=pi, so I'm not sure how far it must be customized
- (until I can move to systemd) how should I modify my current init.d domoticz.sh to support Python virtual environment ? The wiki states to add 1 line (without telling where), but on the forum I found another post stating to add 2 rows
In the do_start() function, before the line start-stop-daemon --chuid $USERNAME --start --quiet --pidfile $PIDFILE --exec $DAEMON --test > /dev/null || return 1, add:

export VIRTUAL_ENV=/home/pi/Domoticz_Python_Environment
export PATH="$VIRTUAL_ENV/bin:$PATH"
- do you thin the errors below are linked to these Python virtual environment ?
