You can set weekly schedules for your air conditioners, monitor usage history, set air conditioning action in relation to your locations, see the air filter status of your AC and lot more. You can set intelligent temperature based triggers for your air conditioners by using the ‘Comfy’ feature under ‘My Rules’ section of the app. Comfy lets you set triggers to personalize the operation of your AC.
