I need to keep two thermostats in the same mode since they are on a two zone system - so both on HEAT, COOL, OFF, but they should still heat or cool based on their own temperature settings. So just syncing ModeStatus between the two - making sure one floor can’t try to heat while the other is cooling.

Device Properties:

SecondFloorMode Second Floor Thermostat ModeStatus
ThirdFloorMode Third Floor Thermostat ModeStatus

Conditions:

ModeMismatch2ndFloorChanged No (SecondFloorMode ne ThirdFloorMode) and (ThirdFloorMode; SecondFloorMode)
ModeMismatch3rdFloorChanged No (SecondFloorMode ne ThirdFloorMode) and (SecondFloorMode; ThirdFloorMode)

Actions:
ModeMismatch2ndFloorChanged Third Floor Thermostat SetModeTarget NewModeTarget={(SecondFloorMode)}
ModeMismatch3rdFloorChanged Second Floor Thermostat SetModeTarget NewModeTarget={(ThirdFloorMode)}
