Problem adding a switch to a dimmer

Manually another hue white is working. Is setting up the device manually the only way or can I do something about the error?

Sorry for the delay; I tested today with latest snapshot and I think it works ok. I also moved my mosquitto server to docker (moved… I removed my local installation and started a clean new one), and upgrade zigbee2mqtt; it may have helped getting rid of all old messages.

@DesertF0x , I would try a clean openhab instance with latest snapshot and give it a try.

@ccutrer , thanks a lot for your time and your hard work.

Yay! I’m glad! Yes, the latest snapshot has had a lot of improvements. Even just a couple weeks ago I fixed an issue where it wasn’t properly re-creating all the channels immediately on boot, and had to wait for the MQTT discovery messages to come in. I think that was the cause of the occasional “channel not supported message” (because the item was getting linked before the channel was created).

I am on the latest stable version and I am getting that message:

12:22:07.517 [WARN ] [mqtt.generic.AbstractMQTTThingHandler] - Channel mqtt:homeassistant_zigbee2mqtt_5F0x001788010d734ebb:9e68bf1327:LichtBad:brightness not supported!

when I command the connected Item. And no command is send to MQTT.
Reading “brightness not supported” sounds weird to me as it is such a basic thing.

@DesertF0x , I tried last snapshot.

services:

I don’t know if I will have to do anything to return to stable, but at least everything works now.

Ok, I will wait for it to become stable. I do not have time to deal with other issues that might be in the unstable version.
