@scottb I’m not sure yet how to fix it, but it looks like ZHA is sending a command with “medium” value when you turn the fan on. It should be sending “on” I believe. I can confirm that this doesn’t happen on Z2M.

If it is in On/Off mode it should only use the high speed even though the level is not showing correctly. So it shouldn’t cause any problems with the fan, but I see that it is confusing an will see if I can figure out what is going on in ZHA.
