This is a shot in the dark. I’ve been running HA for over two years now, but just in the past month or so I’ve been getting some odd behavior that never happened before.
Basically, smart switches and door sensors are triggering “on” or “open” but not “off” or “closed.”
That said, I might not notice if HA misses “on” events for the things I’m monitoring (run time of my boiler and sump pumps.) so it could missing those, too.
Remember, I went for two years virtually never missing an event. I keep the software current and I’m running on the same RPi 3B+ and the same Zigbee and WiFi networks. It’s happening with both Zigbee and WiFi devices.
I don’t even know where to begin troubleshooting. Most people who use HA for voice control and things like that probably wouldn’t even notice. I was hoping maybe someone else who uses it for monitoring might have wondered why their numbers suddenly don’t add up and we could compare notes and maybe pin down the source of the problem.
