It would be useful to be able to pause Thermostat Schedulers when working on an HVAC system.
Also, an option to change the Setpoints without modifyign the Mode would be great. Currently, Thermostat Scheduler changes the Setpoints and turns on our (Lutron RRA2) HVAC if it is disabled.
Perhaps you could show your setup page. You can pause it just by disabling the app on the Apps page.
You don't have to set the thermostat mode at all. None of my Thermostat Scheduler instances touch the thermostat mode or thermostat fan mode (using Lutron RA2 thermostats). I manually set thermostat modes seasonally.
