It's a Honeywell T6 Pro, and I've tried the "Generic Z-Wave Thermostat" which doesn't work at all - can't even use the device to set the setpoint. "Generic Z-Wave Plus Thermostat" does seem to control the thermostat, but doesn't work as indicated in scheduling. Also, the user installed "Advanced Honeywell T6 Pro Thermostat" controls it fine, and is what I had been using until I was trying to work around the homekit auto mode issue, and was working fine in scheduler last I tried, a month or two ago. But, changing back to that driver now, still doesn't work in scheduler. Also, note that I can change the fan and mode in the Manual section of the scheduler, just not in the schedule section.
