Maybe you need to adjust the time for the “Auto off” function a little bit (parameter 156 or 157).
I think I did…but I wasn’t able to get my head around what causes the behavior. When (if) I do an effort to fix it and find out why it does that I’ll try to remember to report back.
Did you end up powering it by battery or something else. I’m also in need of a battery powered device.
Since I went with the Fibaro implant I gave it power from one of the power outputs of my garage door motor, so no battery needed.
