The tado Smart AC Control is a pioneer in a new age of intelligent air conditioner control. It automatically adjusts the air conditioner based on your location. The tado app on your smartphones detect how far you are away from your home and sets the temperature accordingly. Tado’s device interfaces with over 85% of the world’s air conditioners, including both portable and window units. After being placed near the air conditioner, the system connects to your home’s WiFi, and uses infrared to issue commands to the unit. Smart AC Control allows users to interact with their cooling system much like traditional smart thermostats do, you could have the system pre-cool before you get home, and automatically turn itself off to save energy when you are away.
