I have a few battery powered Z-Wave devices. I’ve tried monitoring their battery levels to know when they are getting low, but finding they die at random levels. For example, My Aoetec PIR went flat but was still showing batteries at 74%.
The issue really, is that I don’t actually know it’s gone flat, as HA still sees the device per it’s last state. I’ve also had recessed door sensors go flat and I don’t notice until some automation doesn’t fire.
Does anyone have an easy way to detect if a Z-Wave device has not sent an update in X period, which I could then feed into an automation? Devices usually check in once an hour or so (depending on config), but there doesn’t seem to be a built in way to deal with devices that have gone ‘stale’
