I have connected it to a Broan Nutone fan. I don’t think it is an issue with the fan. I tested with fan disconnected, the switch is always on. I have tried to manually change the smart fan mode but that didnt fix it. I have tried the air gap switch and it disconnects the power to the fan as well. Anyone knows what might be going on?
Factory reset it. If some setting inadvertently stuck, that should resolve it. The default is Smart Fan Mode off.
Unfortunately that did not resolve the issue. Did factory reset by holding config + paddle up button for 20 seconds. Did this multiple times.
Did it work properly after installation and then fail or has it never worked properly?
I thought factory reset is holding down up paddle and configure button until it goes through led bar colors green, then yellow, lastly red then let go (about 15-20 seconds).
That’s correct.
