I have an Inovelli Red dimmer connected to hot, neutral and ground. I have a rule that when I turn it on (button 1 push) it should turn on the light that is connected to an Inovelli fan + light. It had been working, but has now stopped. I did a graceful shutdown and reboot (that helped a bunch of other switches as everything seemed to be getting sluggish) but not this. The fan + light is in the same room as my hub and this switch is just on the other side of the wall, so distance isn't a problem.
I don't know how to read the logs, but when the switch is pushed I can tell Hubitat sees it, because the below actions appeared in my live log.
I pulled the air gap on the outside switch (the one that isn't working), waited over 30 seconds and then pushed it back in. When I did that the light came on and stayed on and the fan came on for a second and then turned back off. I turned the light off from inside and then turned it on from outside one time. That worked, but the outside switch didn't work to turn it off, and when I turned it off from inside I couldn't turn it back on from outside. So pulling the air gap only worked to turn it on that one time.
