The Honeywell T9 Smart Thermostat doesn’t call much attention to itself. Either pro or a con, depending on your perspective.
Inoffensive industrial design
- The T9’s rectangular shape doesn’t do much to move the needle in terms of design; on the other hand, it’s not at all edgy.
- It resembles the Honeywell Lyric T5 (our current favourite budget-priced thermostat) but is more aesthetically pleasing, with a white bezel surrounding a bright white 3.5-inch touchscreen.
- Coloured text displays the indoor temperature (orange while heating, blue while cooling) and gray text shows the temperature outside. Icons report on weather conditions.
- The thermostat’s home screen displays the current indoor and outdoor temperatures and icons to indicate the current weather conditions.
- Tap its screen, and you’ll get be presenting with more detailed information about the heat-to and cool-to temperature targets you’ve set.
- Along with an indoor humidity reading (but you’ll need to step up to professionally installed Honeywell Home T10 Pro if your HVAC system includes an integrated humidifier).
It’s all about those sensors
- But occupancy sensor support is easily the Honeywell Home T9’s most crucial feature. You can buy the thermostat without any sensors for $169 and add them later for $40 each on Amazon.
- Still, most people won’t want to—especially since the $200 thermostat-and-sensor bundle gives you a $10 discount over buying the two components separately.
- These small square devices are outfitting with motion, temperature, and humidity sensors and subtle indicator LEDs.
- You can deploy up to 20 of them, which should be enough to cover every room in the average home. They’re powering by two AAA batteries, which Resideo says should last for one year.
- The thermostat will then endeavour to have your HVAC system relaxed or warm your home until the occupied rooms reach the programmed target temperature.
- You can also set different temperature targets for each room served by a sensor and select which rooms should have priority.
- In this scenario, the thermostat will average those numbers and set that as the target temperature for the entire home.
Smart home integrations
- Suppose you’re looking for a thermostat that you can integrate with your intelligent home system.
- In that case, the Honeywell Home T9 supports Samsung SmartThings and IFTTT, and it’s compatible with Amazon Alexa, Google Assistant, and Microsoft Cortana.
- Once connected, you can check the temperature of any room with a sensor (although strangely, not the humidity level) and even command the assistant to adjust the temperature of any given space.
- Apple HomeKit support is in the works (the earlier T5+ and T6 Pro already support HomeKit, so this shouldn’t be a big hurdle). You’ll find a complete third-party support list here.
- The Honeywell Home T9 isn’t the prettiest or most high-tech smart thermostat on the market. We still prefer the similarly Ecobee4 for its integrated smart speaker.
- The third-generation Nest Learning Thermostat remains the most beautiful device. In this category (and it’s the best choice for those deep in the Nest ecosystem).
- But the way the T9 works in conjunction with its room sensors puts it up high on our list of recommended smart home. Devices for anyone moving up from a conventional thermostat.
