The Honeywell Home T9 Smart Thermostat brings artificial intelligence to home climate control — learning your schedule, sensing room occupancy, and automatically adjusting temperature based on where you actually spend time. As Honeywell’s flagship smart thermostat, it combines 125+ years of HVAC expertise with cutting-edge AI to deliver unmatched comfort and energy efficiency.
About This Item
- AI Room Priority Technology: The T9 prioritizes the temperature where people actually are using occupancy data from Smart Room Sensors. Working late in the home office? It prioritizes that room. Everyone in the bedroom at night? It shifts focus there automatically.
- Geofencing – Home/Away Sensing: Uses your smartphone’s location to automatically switch to energy-saving Away mode when you leave home and pre-conditions the house before you return. Never come home to an uncomfortable house again.
- Flexible Smart Room Sensor Support: Add up to 20 Smart Room Sensors throughout your home (sold separately) for comprehensive multi-room temperature monitoring. Each sensor reports temperature and occupancy data to the T9 for whole-home intelligence.
- Works with Every Major Smart Home Platform: Full compatibility with Amazon Alexa, Google Assistant, Apple HomeKit, Samsung SmartThings, and IFTTT. Control your thermostat via voice commands from any smart speaker or display in your home.
- 7-Day Flexible Scheduling: Create unlimited temperature schedules for every day of the week with up to 6 separate time periods per day. Combine with geofencing for a completely automatic climate control system that adapts to your lifestyle.
- Energy Usage Reports: Monthly energy reports delivered to the Honeywell Home app show exactly how much energy your HVAC system used and provide personalized recommendations to reduce consumption without sacrificing comfort.
- Universal HVAC Compatibility: Compatible with 95% of all HVAC systems including forced air, heat pumps (with or without auxiliary heat), boilers, and radiant systems up to 4H/2C. Includes a C-wire adapter for systems without a common wire.
