Hello irmi29, welcome to nymea!
Yes, indeed, the tasmota plugin is lacking a little. I can improve the 4 channel stuff. The main reason why it’s not there currently is that I lack hardware to test with but if you’d be willing to test things for me we should have that supported pretty soon. I’ll see if I can squeeze that in later today, it’s all prepared.
to be honest it’s the first time I hear about zigbee2mqtt. It’s seems an interesting project.
Now, I assume (without having it tested) it would work in nymea, with some setup effort:
You can enable the MQTT server and set up things so the zigbee2mqtt gateway can connect to it. From there you can use the generic mqtt client plugin to set up things based on mqtt. Once done so, you’ll see “uncategorized” things appearing in nymea. If you want to use the pretty interfaces (for lights, roller shutters etc) you can use the “Generic interfaces” plugin to set that app and then use the Rule engine to create rules. (e.g. if light from generic interfaces is turned on, execute action publish on the mqtt device)
We are aware that this is a bit fiddly and we have worked out a plan to improve that situation in the future (can’t give a time estimate but I hope somewhat soon).
If you want to play around with this and would like to get more real time help and give feedback on how we could improve the situation for your setup, you are welcome to join our telegram group as well if you like.
