The latest T-series thermostats feature wireless sensors that measure temperature and humidity on a room-by-room basis. The thermostats will be compatible with HomeKit later this year, according to an Apple spokesperson, allowing them to be controlled in the Home app on iOS and macOS and with Siri.
The smart room sensors offer a few other features, including people detection that ensures occupied rooms are at a desirable temperature, and a 200-foot range to help deliver whole-home comfort, according to Resideo.
The T9 and T10 Pro offer simple scheduling, geofencing, and compatibility with demand response programs that may qualify for utility rebates in select regions. With the companion Honeywell Home app on iOS, homeowners can set temperatures per room, switch which room is prioritized, receive temperature alerts, and more.
The T9 can "configure itself with its wire-sensing technology and includes a C-wire adapter, making do-it-yourself installation very simple," while the T10 Pro requires professional installation due to its humidity and ventilation controls.
Resideo says the new T-series thermostats will be available in North America "this spring." At launch, the thermostats will integrate with Amazon Alexa and Google Assistant. Resideo's press release does not mention HomeKit support, but an Apple spokesperson confirmed the platform will be supported "later this year."
The T9 with one sensor will be available at major U.S. retailers nationwide and at HoneywellHome.com for a suggested price of $199.99. The T10 Pro will be available via professional heating and cooling contractors. Additional smart room sensors can be purchased in a package of two for $79.99.
