This add-on sensor for Sensibo Air models delivers additional comfort and savings to your split system air conditioner. Sensibo will automatically turn your AC off or to a more efficient setting if it doesn't detect occupancy after a pre-set time. On entering the room Sensibo can be set to automatically start your AC, or just do nothing if the rooms just right. The sensor also has built-in temperature and humidity sensors so you can monitor the climate of a room remotely.
