I have two and have been using them happily for years but recently topped working.
Now I’m investigating and neither device even appears in Z2MQTT any more!
I can’t seem to bind them either - tried new batteries
Any logs in z2m?
well, typically enough (I assume due to the laws of Sod!) one just interviewed successfully, after many previous attempts I promise!!
Guess I’ll just keep on trying many more times with the other!
