AVM FRITZ!SmartHome: Sensors going off and on for no reason

Tags: #<Tag:0x00007fc42f3c6a18>

Hi there,
I‘m using the official Fritz!box-Integration but having trouble with my contact-sensors. They seem to be not responding and are coming back repeatedly during the day. That triggers automations everytime they get available. Batteries are fine. Any suggestions what to do?

Hi @fogger
which contact sensor devices you are using?
Are there other devices having same issue, or only these contact sensors?
Do you see any thing useful in the HA log?
