Domoticz

I now reverted back to using the script and shellyplus2pm-xxxx-roller-pos instead of no script and shellyplus2pm-xxxx-roller-pos-c

As Shelly teacher has been archived and not supported anymore perhaps this script could be interesting, it supports a lot of Shelly devices using MQTT https://github.com/bieniu/ha-shellies-d ... ree/master

Sorry for my stupid question: As it seems to be for Home Assistant: What must I do, to integrate it into Donoticz?

If the Python script will run it seems to check what Shelly devices are in your network and create MQTT autodiscover config topics for them, so when you enable the Domoticz MQTT AD hardware gateway all the discovered Shelly devices will be created and updated in Domoticz.
Ideally you run the python script only when you have added a new Shelly device in your home.

Merci
