Honeywell Home RCHTSENSOR-1PK — Smart Room Sensor for T9/T10 WiFi Thermostats

Enhance room-by-room comfort

Meet the Honeywell Home RCHTSENSOR-1PK, a compact wireless sensor that measures temperature and humidity in multiple rooms to help your thermostat respond where you need it most. Its unobtrusive design fits discreetly in bedrooms, living areas, or home offices, giving you smarter, more targeted climate awareness without adding clutter.

Designed to pair with T9 and T10 WiFi Smart Thermostats, the sensor enables the thermostat to create an average temperature view across rooms and adjust heating or cooling accordingly. This makes it easier to maintain a consistent feel in your home, room by room, without constant manual tweaks.

How it helps your home

Place sensors in the rooms that matter—bedrooms, living areas, work areas—and watch how occupancy cues and a chosen schedule guide comfort toward the spaces you use most. Motion detection helps the system focus where people are, making transitions between rooms feel natural rather than abrupt.

• Focus on rooms people spend time in, using motion sensing to guide comfort.
• Set bedrooms to a cooler profile at night to support a restful sleep environment.

What to expect during setup

Installation is designed to be simple and tool-free. Use the Resideo app to connect each sensor to your compatible thermostat, then manage room focus and schedules from one place.

• DIY installation with no tools required.
• Control and monitor from the Resideo app anytime, anywhere.

With multi-room focus, the T9 system collaborates with the sensors to create an average temperature across spaces, helping you feel balanced comfort throughout your home without constant adjustment.
