That’s what I do with my dumb washer and dryer. Notifications when the washer and dryer are done, and nagging reminders if the washer is done, but the system doesn’t see the dryer turn on after some time (eg the wet clothes are still in the washer). If the washer finishes, but the dryer is still running, it tells me that too, then waits for the dryer to finish before resuming the wet clothes notifications.
I use Z2mqtt and still get random powered devices showing as unavailable. Too bad there isn’t a “ping” feature like ZWave.
Nothing moves, and yet I get random unavailable devices that come and go randomly.
I guess I need to check my WiFi channels. One of my biggest complaints around Zigbee vs ZWave. I don’t have these issues with my ZWave devices.
