Put your comfort on your terms using location-based temperature control with geofencing or creating custom heating and cooling schedules with the flexible 7-day scheduling option. Both energy saving features help to reduce your HVAC related energy costs so you can save money without compromising your comfort. Plus, Sensi integrates directly with Amazon Alexa, Apple HomeKit, Google Assistant and Wink home automation platforms. Connect to Amazon Alexa to control your home temperature with simple voice commands, or just ask Siri to set, raise or lower your home temperature when using Sensi with Apple HomeKit.
