    Customers like the ease of installation of the HVAC control thermostat. For example, they mention that the connectivity is easy, programming is easy and the app works well. Some appreciate the simple and responsive design. That said, most are happy with the ease and functionality of the product.

    Customers like the customization of the HVAC control thermostat. They mention that it gives them the ability to control all options of a heat pump, not just temperature. They also appreciate the versatility, great features, and ability to check/set each zone from the app no matter what their location is. Customers also say the design is clever, comprehensive, and refined.

    Customers are mixed about the quality of the HVAC control thermostat. Some mention that it's awesome, they really like the settings and all the options, and they're able to control the heat for specific rooms with this thermostat. They also love the adjustable temperature remotely, and the crossover temp is easily adjustable from the installer menu. However, others say that it failed and started sending voltage, had poor heating, and wouldn't switch to cool. The default from the factory does not work for a heat pump, and it'll not measure the bedroom temperature.

    Customers are mixed about the performance of the HVAC control thermostat. Some mention that it works great, while others say that the app is glitchy and doesn't always work the first time they open it. Some say that nothing regarding smart features works, and the full time heat setting started to fail.

    Customers are mixed about the app. Some mention that they love the Honeywell app and it's integrated into their Samsung Smartthings app. They also say the thermostat and sensor is a nice addition to an automated home. However, others say that the Resideo app is by no means great, highly convoluted, and glitchy.

    "...The Resideo app is by no means great, as it must be force closed to get the latest data from the T10 every time you make a change, but it's simple..." Read more

    "...I love the Honeywell app...." Read more

    "...The Honeywell app is however very basic." Read more

    Customers are mixed about the remote control of the HVAC control thermostat. Some mention that it's essential to them, while others say that it rarely works. Some customers also say that the app does not work with the remote sensor, and geofencing does not function.

    "Only issue I have had was my cellphone not wanting to work with it. I contacted Honeywell tech support and quickly had it working perfectly" Read more

    "...Pros include Geofencing, control remotely, works with additional sensors, works with Google Assistant and Alexa, Scheduling, on phone app and more...." Read more

    "...will not function and, most importantly, there is no remote access/control for the unit. Ended up returning them." Read more

    Customers are mixed about the sensor. Some mention that it works with additional sensors, and is programmable. They also appreciate the ability to add a room sensor to help balance the room. However, others say that the sensor feature has a major flaw and the main unit does not itself have an occupancy sensor.

    "Like everything about the thermostat including the ability to easily add room sensor to help balance room temperatures in closed separate rooms such..." Read more

    "...Finally, the main unit does not itself have an occupancy sensor, so you need to buy an extra sensor to put in the same room as the thermostat..." Read more

    5 customers mention0 positive5 negative

    Customers are dissatisfied with the stability of the thermostat. They mention that it won't stay online, it drops the internet connection occasionally, and it sends 5-6 offline alerts daily. The app logs them out too often and the WiFi stopped working after 3 months.

    "...Another problem with the Honeywell/Resideo app is it logs you out too often requiring to log back in which is frustrating...." Read more

    The next best thing - problem solved
    Problem existed upstairs in our home that a bedroom got either too cold or to warm depending on the season. Reason: thermostat is installed in the hallway and the the hallway doesn’t have a dedicated air stream. Once the bedroom doors are closed, the thermostat is “isolated” and is doesn’t measure the bedroom temperature. Consequently, during summertime the airco remains running until the bedroom feels like a freezer. We often use 1 of the 2 upstairs bedrooms and I was considering moving that thermostat into that bedroom. Then I googled for remote sensors which brought me to Honeywell. I prefer Honeywell because I installed a bunch of their more simple WiFi types (RTF6….)in all our rental houses. For our home I picked T10 because a little more functionality than T9 at only a small price difference (Likely will never use these functions). We have a conventional gas/electrical 1-stage heating/cooling system. Installation is easy (5 wires). The remote sensor installed in the bedroom comes with batteries and double sided tape.The key function I was looking for is that now I can select the bedroom temperature to be controlled. Or, if I would like, I could activate the hallway as well and it would control off the average temperature from bedroom and hallway combined. Anyway, that’s not what I prefer.The other thing I was looking for In a thermostat is auto changeover, thus automatically select either heating or cooling depending on the temperature, which can be relevant during spring an autumn. T9/10 have that functionality if selected. Works.Last but not least I connected it to WiFi to add it to my Honeywell app TCC which I utilize for remote access for all our rental houses. Surprisingly, T10 (or T9 for that matter) is not compatible with Honeywell TCC! Which was disappointing. Instead I had to download the Honeywell Home app. On the positive side it was very easy to import all other locations/thermostats from TCC into the new app! I ended up still using TCC for the rental places because it provides me with a better overview page ie I see at one glance if something is out of wack.

    Reviewed in Canada on October 28, 2023
    I bought this thermostats for my new AC. I wanted wifi and another sensor in my bedroom since the bedroom is not cool enough for my liking. Wifi works and sensor is works kept my bedroom cool enough for me while I sleep. However, other areas in my place was way cooler. During the day I adjust the bedroom temperature up so the rest of the place is not freezing. I was able to connect the app to Alexa and works so far. Now season is over….will have to see next summer.
