Does anyone else experience this? my z-wave Motion sensor defaults to detected when battery dies and at the same time cause my automation to trigger too. it happens with multiple brands. it keeps it in a detected state until you change the battery. Not good when I go on vacation and it happens to keep my lights on the whole time.
There should be a button entity in home assistant you can use to manually set it or automatically via an automation. For me I disable light automations when I’m away and instead generate alerts from the motion sensors for intrusion detection.
Actually, one of my motion sensors has been generating frequent false motion detected events lately. I noticed because that one drives an automation that turns on a light. Quite annoying. “By coincidence”, its battery died today so it could well have been what you’re talking about.
Hopefully, it will behave sensibly again now that it has a fresh battery.
