MQTT Binding 2.4 via Docker on Synology - Aqara Sensor & Osram Smart Plug

In short for a switch create an On/Off Type channel, for the temperature a number channel.

It’s not these settings. I had already read this out in the instructions.

For both to report their respective state back the state topic has to be set, for the On/Off you need to set the commandtopic as well.
You do have the needed settings in your MQTTfx.

can you show me how and where?
