Honeywell's Unusually Smart Home Thermostat Finally Receives HomeKit Support

Cupertino, November 10, 2021

After several years of promise, one of the first smart consumer thermostats to support remote temperature and humidity sensors, the Honeywell Home T9, finally offers support for the Apple HomeKit and Siri voice control.

Ask Siri to control the Honeywell Home T9 smart thermostat

Resideo, the owner of the Honeywell Home brand, promised to make the T9 HomeKit compatible about two years ago. It already offers support for Apple's smart home system in its T5 thermostat, also called Lyric T5. But that device does not work with external sensors.

Adding HomeKit compatibility to the T9 is an important step. The thermostat's remote sensors help ensure comfortable conditions in different rooms - not just in the immediate vicinity of the thermostat.

And the sensors have a good reputation not only for accurate temperature readings, but also for humidity measurements. Remote sensors from other manufacturers, such as Nest and ecobee, do not measure humidity.

The sensors also detect movement and presence and adjust the system to focus on the rooms in which they detect people.

With HomeKit support, users can now control their Honeywell Home T9 thermostat using the Siri voice-activated assistant or the Apple Home app. They should be able to use automation to adjust conditions.

The thermostat does not include a built-in voice assistant, so users must display Siri using a HomePod Mini, iPhone, iPad or Apple Watch.

The future standard of matter

When the new Matter standard is released in 2022, Residio's current move to add HomeKit support may not be as important. The company is part of the Connectivity Standards Alliance board of directors, helping oversee the launch of Matter.

The first Matter specification includes smart thermostats, so the Honeywell Home T9 would probably have accepted the standard soon anyway, making the thermostat compatible with any smart home system.

But for those with T9 thermostats - and for HomeKit people who might like it - having compatibility sooner rather than later is great as winter approaches.

The Honeywell Home T9 smart thermostat comes with a sensor and supports up to 20.

Price: $ 199
