Domoticz Addon

Hi,

Sorry for using this old topic, but I find it appropriate.

First of all, my setup. LibreElec is on my Raspberry Pi4. I added Docker and linuxserver add-ons, especially Domoticz. I have a RFlink gateway connected via USB to the Raspberry. The gateway is connected to port /dev/ttyACM0, which I set up on Domoticz add-on configuration.

My problem now. When I add the gateway to Domoticz hardwares, Domoticz log returns "Error opening serial port" every 30 seconds.

I know the gateway works because I've tested it on Windows and, moreover, with Home Assistant that I previously installed on the same Raspberry. I can see things coming on this port with cat /dev/ttyACM0 (unreadable but presumably RF messages).

Do you have an idea where it could come from?

Thanks.

Docker containers are sandboxed. They only have access to things that you specify. Go into addon settings, turn on additional parameters and input "--device /dev/ttyACM0” and see if that works

I've already tried that on a fresh install. It did not work, then I saw the switch to enable USB pass through, which I activated and entered /dev/ttyACM0 as parameter just below.

P.S.: I just tried a new install with your suggested parameter and I confirm I get the same error messages. Actually, previously I typed "--device /dev/ttyACM0:/dev/ttyACM0", which seems to be the same...
