The Sensibo Sky is a basic AC controller. The Sky allows you to control your AC from your phone and offers a range of app based features such as geo-fencing and 7-day scheduling. The Sensibo Air is our controller for PRO users. It is designed for those who are looking for greater accuracy in their home climate and even more energy savings. It integrates with Apple HomeKit, uses a more advanced chipset and supports WiFi & Bluetooth Low Energy. It is also smaller, can naturally be placed on a table or shelf, or hung on a wall. The Sensibo Air can be extended with our truly wireless Room Sensors (also available as a bundle).Β
