Recipes that need this role
Presence Thermostat Setback

Window Open HVAC Pause
Installs a Home Assistant automation that turns the thermostat off when a window is left open, so you are not heating or cooling the street, and turns it back to the mode it was in once every window is shut. Add door sensors and a temperature sensor for the full picture.
