@Snille Wow, I am so glad to hear it. I made a test with my real MagicMirror, and a dummy one running on a linux laptop. At this point I added a real uniqueID for the HA device config jsons.
@Snille said in MMM-HomeAssistant:
Update: I did some cleaning in the MQTT-queue (with MQTT Explorer) and now it all works. I got to have had my config(s) mixed at some point during my testing. So, now it’s all good. :)
Hmm, alright!! I will try to think of a handling in case two MM instances want to connect with the same device name. That is the only attribute left on the user.
