Just following up on my post earlier (sorry If I’m spamming the thread). I just got two of these occupancy sensors in the mail yesterday.
Unfortunately they don’t yet work with ZHA. I put in a device support request. I tried appending the manufacturer info to the quirk for other mmWave devices, but I can’t get the entity to show motion. (see: [Device Support Request] · Issue #1590 · zigpy/zha-device-handlers · GitHub)
It appears to be the same basic design as the sensor mentioned here:
It will likely have the same kinds of issues as the wifi version given that they both use the same sensor module. So, I can’t really recommend the radar device at this time.
So, there’s a working custom quirk available on the ZHA device handlers github. In my house I have these on a wall pointed at places where I’d be sitting still/working but not making movement that a PIR would catch. So far there are very few false readings. I really like these so far. It seems like they take some time to calibrate – I had a lot of false alerts initially but none now for two days.
Assuming that a quirk is written to adjust cooldown time (24 seconds is what this can do!) and adjust target distance, this would be a perfect occupancy sensor.
