Honeywell Home T9 WiFi Smart Thermostat with 1 Smart Room Sensor – White

The Honeywell Home T9 Smart Thermostat pairs with Smart Room Sensors to tailor climate to the rooms you care about. View each space’s temperature and humidity on the touchscreen or in the Honeywell Home app, and let the system balance comfort across the home as occupancy shifts. The result is a flexible, intuitive way to manage your indoor climate without micromanaging every room.

Smart scheduling and remote control

Set routines that fit your day or let Auto Home/Away adjust the temperature based on activity. With built‑in Wi‑Fi, you can tweak settings from anywhere, whether you’re at home, at work, or on the go. In your area, your energy provider may offer rebates, and some utilities run demand‑response programs that reward small, temporary temperature adjustments during peak times.

• Control the thermostat via the Honeywell Home app or with voice assistants such as Alexa, HomeKit, and Google Assistant.
• Auto Home/Away and room-focused adjustments help optimize comfort and efficiency.
• Compatible with a wide range of heating and cooling systems, including forced air, hot water, steam, and heat pumps with backup electric heat.

Room-by-room comfort with Smart Room Sensors

Place sensors in bedrooms, living spaces, or a home office to monitor temperature and humidity in each area. The T9 uses sensor data to focus comfort where people are, while the touchscreen provides a quick, at‑a‑glance view of room conditions and trends.

• Reliable sensor range up to 200 ft, depending on home layout, for steady communication.
• Automatic balancing helps reduce hot or cold spots across rooms.
• Easy DIY installation with a low‑voltage power adapter when a traditional C‑wire isn’t available.

Before you buy, verify compatibility with your HVAC system and whether your home needs the C-wire adapter. The T9 is designed for a broad range of setups and adds a modern, streamlined control surface to your climate management.
