Honeywell Home T9 thermostat

23. 7. 2019 | The Verge | www.theverge.com

In the world of smart thermostats, what separates the top models from the rest of the field is the ability to measure the temperature in more than one spot in your home. That allows you to regulate the heating and cooling functions in the areas where you actually are, instead of where the thermostat is mounted. To do this, smart thermostats utilize small, wireless remote sensors that can detect temperatures and then integrate that data into their algorithms.

Ecobee was the first consumer-based smart thermostat to utilize this kind of feature. Now, with the T9, Honeywell Home has a thermostat of its own that supports remote temperature sensors. The $199 T9 comes with one remote sensor in the box and can support up to 20, compared to the 32 sensors that Ecobee can handle and the maximum of 18 that Nest supports. In addition to measuring temperature and detecting presence in a room, the T9’s sensors also have the ability to measure humidity.

Wireless thermostat T9

Aside from the remote sensors, the T9 has all of the features you’d expect from a smart thermostat, including support for a variety of HVAC systems, time-based or geofenced scheduling, and a smartphone app to control your system when you’re not home. It also supports both Amazon’s Alexa assistant and Google Assistant for voice control.
