I have two of these thermostats, the Honeywell YTH8320ZW1007/U Z-Wave Enabled Programmable Thermostat. I've been having some issues with the thermostat going off-schedule mid-day and opened a case with Honeywell.
They indicated that while the thermostat has a built-in scheduler, it is best if the controller manages the temperature setpoints for the unit.
I explained I had SmartThings and they had no idea how to help.
Does anyone know how I can control the 7-day program scheduler - or make my own schedule - for this thermostat through ST hub?
