I have been slowly converting my home to a "smart house". So, I have experienced a lot of smart device successes and failures! That said, the T9 has certainly been a success! By success, I mean it provides all the modern features you would want from a wifi connected device, plus a few features not offered by the competition. I found it easy to install and super easy to configure. I appreciate that it supports either 2.4 or 5 GHz wifi networks. I also found the display to be of high quality, and it was as easy to use as my iphone touch screen. I also use the Resideo phone app to control the thermostat. I found the app to be intuitive and easy to use. Here is what sets the T9 apart. The remote temperature sensors!!! We have two rooms that are often 3-5 degrees different from the rest of the house. One of them is our bedroom. I placed a T9 remote sensor in each of the two rooms, and the two rooms are already much more comfortable. Because the T9 allows you to setup the thermostat temperature control at the base unit on the wall, and/or at the remote sensors, I have greater control of the temperature in our house. When using the remote sensor(s), the T9 allows you to select which sensor is used to control the thermostat. The remote sensors can be configured to work in one of two ways: 1) become operational when they detect a person is in the room 2) just to operate as a temperature probe for the room. This is important because the T9 allows you to change how and when the remote sensors are used to control your HVAC system. As a "programmable" thermostat, you can select the desired temperature based on the day(s)-of-the-week and the time-of-the-day. However, the T9 also allows you to select which temperature sensor is used to determine the room temperature during different times of the day! Here is an example: We have three T9 temperature sensors (one at the thermostat display and two remote sensors). During the week days, we use the average of the temperature between all three sensors. At night we only is the remote sensor in our bedroom to control the temperature. On the weekend, we only use the remote sensor in my "office" if someone is in that room. Otherwise, the average of the other two sensors are used to control the temperature on the weekend. The ability to select which sensor (or combination of sensors) are used to determine the control of out HVAC system has been a game-changer, and it has really helped us make our home more comfortable! One more thing. We wanted a small thermostat that blended into the background of the wall. The T9 does this wonderfully. Unfortunately, many of the other modern thermostats want to make a bold statement with their glossy black appearance (also with their large size, and as they stick way out from the wall)! Making a bold statement may be fine for an expensive car, but it is not what we wanted from our thermostat. Last thoughts: Many other reviews cover the need for a "C-wire", or the fact that you may have to do some wall painting when replacing an older thermoset. I'll just remind you to consider these things before buying the T9. However, if you have isolated rooms in your house that vary in temperature, then the T9 with the optional remote sensors is a great option for you! Oh, BTW. The remote sensors stick to the wall using 3M Command strips (provided with the device). They are battery operated, and they claim to have over a year of battery life on AAA batteries. They connect to the main unit using a proprietary wireless connection.

I upgraded to this thermostat from the Honeywell T5. To my surprise, I didn't have to rewire the wall plate. Honeywell's thermostats use the same wall plate so all you have to do is unplug the old one and plug in the new one! The T9 is more user friendly in that when it is heating, the background is orange, and when it is cooling, the background is blue. The temperature (numbers) are large enough so even us older folks can see the temperature from across the room! If you are a DIY'er and you have difficulty with any part of the installation process, Honeywell's customer service is absolutely amazing and will walk you through it; and they are open on the weekends!

If you have never used a thermostat with remote sensors, you really don’t know what you are missing. It is great being able to place sensors inside of rooms instead of having to hope that your hallway is the right temperature. That really only leaves two choices of thermostats, the Honeywell T9/T10 or Ecobee. We recently moved into a brand new house with two separate HVAC systems, one for the main level and basement, one for the top floor with the bedrooms. The builder pre-installed Honeywell T6 thermostats, which left a lot to be desired. They worked well with the Ring system that came with the house, but that control is limited to the mode and temperature. You either need to use the touchscreen on the thermostat or the app to make the most of it. Due to the way the T6 was installed in contractor mode, I could not get them to connect to the Resideo app. The T6 also does not support remote thermostats, which really is a game changer. There are a couple of differences with the T6 compared to T9. T6 has battery backup (I don’t really care as long as it doesn’t lose its programming). T6 connects to Z-Wave, which makes using it with a security system easier (plus Ring only supports two thermostats if they are connected to Z-Wave). Both connect to wifi and both should work with the Resideo app, but I could not get the T6 into the right mode to set it up. T9 has remote thermostats, T6 does not. I wanted more control so I decided to upgrade to the T9. The best part is that it was literally plug and play. I removed the T6 and plugged the T9 into the same wall adapter. I was able to immediately connect it to the Resideo app, which is really what I wanted. The Resideo app is actually not bad, it gives me full control over both thermostats. We have purchased additional remote sensors and have two for each thermostat, I really like being able to place them in bedrooms since we usually have our doors closed. I work from home and have one sensor in my office, one in our living room. I did find that occupancy detection doesn’t work as well as I had hoped because I use a space heater in hopes of saving money and that means the office is warmer than the rest of the house. In the summer and on weekends it works a lot better. With the Resideo app you can easily tweak the settings from anywhere and you can program each day individually. If days match it groups them, but they don’t have an easy way to remove customization for a day. That is nice because I try to go into the office one day a week. I wish I could program heating vs. cooling different for things like the fan because in the winter I want it set to circulate upstairs, in the summer I want the fan off on the top level during the day so I’m not moving the hot air around as much (those vents are in the ceiling), in the winter I want more air circulation. In my previous house we had installed an Ecobee 3, the first model with Apple HomeKit support (which we never used). The Honeywell T9 is competitive with the Ecobee in most of the features you will actually use, but that Ecobee had a couple of features the T9 does not. First, Ecobee supports accessories, for example, you could use it to control a whole house humidifier (I wanted one but never bought one). T9 doesn’t do that. Second, Ecobee can use occupancy to control whether your house is in home or away mode, which would be useful for our top level since nobody is in the bedrooms during the day. T9 uses geofencing, which has a lot of disadvantages in comparison (everybody needs it on your phone, cannot distinguish between home and on that level). Newer Ecobee models add even more sensors and even Alexa. Ecobee also lets you tweak how often the fan runs, Honeywell just has circulate, which runs on their schedule. Ecobee also looks more premium than Honeywell. The T9 is functional but not as modern of a design. Their sensors are large white blocks that really stand out when mounted on a wall. Considering all of the white Ring products I have, it kind of fits in, though. I probably would have chosen Ecobee over T9 if the price was similar, but Ecobee is nearly double the price and their remote sensors are more expensive as well.
