One of 3 stops working correctly after a while

[michaelblight]

Not sure there's much you can do about this, but thought I'd let you know anyway. I have monitor running on 3 Pi Zero W's. Two of them work consistently, but the third one (which is actually a WH) stops working properly after "a while" (maybe a day or two?). I control the scan on door openings, and when it scans, I get results, but when it stops working they're always zero confidence (I think - it's possible the confidence is just not changing when it should). Sending a restart over MQTT makes no difference, but when I reboot it starts working again. All three are on 0.2.200. I'm assuming it's some sort of hardware issue given all three should be identical - I monitor them using glances, and CPU is <10%, memory is ~40% and storage use is ~10%.

Do you know if there's anything I can do to check on the status of bluetooth to ensure it's running ok?

I have the same problem with both Zero and pi 4. Monitor just stops working after about an hour. I am running monitor as service and checking with journalctl -u monitor -f.
