CES 2019: Honeywell Home T9 and T10 Pro Smart Thermostats Debut With Per-Room Temperature Control, HomeKit Later This Year

Resideo today at CES 2019 introduced its latest Honeywell Home smart thermostats, the T9 and T10 Pro.


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.

I think I’ll just use my dumb thermostats and keep my feet warm with the $199.99 I just saved.

“Homekit at a later time” said every company ever and most failed.

The Honeywell app is terrible, so even if they make good hardware it’s not a great product overall.

When setting the timing for the heating, the choices are in 10 minute intervals.... so if you want the heating on at 15 minutes past the hour you’re stuffed.


Maybe it’s just my device, but their app is awful for selecting a comfortable range for auto-switching too. Even when set to “Auto”, I have to manually change to heat and cool and set their respective values, then switch back to Auto. Why in the world??

Alexa’s controls for the same thermostat are way better. When in auto, you see both the highest and lowest acceptable temps at the same time and can set them both.

This is an alternative to Ecobee3/4, but aside from a bathroom, kitchen, or laundry room, I don't know many people who need to know humidity difference room by room because of large humidity differences.

I've been using the T6 for about a year and a half and have been extremely pleased. Only reason I've been considering jumping ship was the lack of sensors, so I'm very pleased to see that it will be very easy to swap these out - same wiring!

Hopefully one can disable Alexa and Google Assistant - I'd prefer not to have them reporting (and perhaps listening) 24 x 7.
