I have a couple of these old sensors laying around and never really got them working with Home Assistant and ZHA. I did notice there are some old threads with some custom code (like THIS ONE), but they seem abandoned. I am leary of using code >6 months old at this point.
Not sure how long ago it was implemented, but I did notice that I now have zha.entity entity ids that list the mac address, lqi, and rssi. The state also shows online/offline. This is very useful in general.
It seems like this should be usable in making the presence detectors work by creating some template binary sensors based on online/offline status or even rssi. The problem is, the sensor never goes “offline”, even if I remove the battery for an extended period of time. Are there any other workarounds for this?
