I have a GE Dimmer Switch using the Generic Z-Wave Smart Dimmer driver that is no longer showing activity in the log since 10/7, yet the light responds to manual changes, digital changes via the device page and via automation.
The device shows it being on, even though I turn it off/on/refresh... One of my RM rules based on lux didn't work today b/c the switch was reporting as on when it was actually off
This happened to me for many months now. A device would quit logging events yet automations continued to work. I had to exclude and re add it to get it logging events again. I ended up replacing my problem devices with Plus models when they were on sale many weeks back.
