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.
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.

Works great. I have a heatpump system, and had no problems hooking it up. It has a weekly schedule if you want to set five days easily, or you can do all seven separately. I set mine for weekday and weekends (two schedules).
Has four daily slots (rise, leave, home, sleep), but looks like you can add more.
I bought two room extenders, and they work great. I have an older house, and the thermostat was in a hallway that was off the main area. The room extenders are great as they were easy to add and let you tell the thermostat what to weigh on heating/cooling decisions. Are you in the living room or your office all day? Set the thermostat to look at that sensor. Your bedroom hot at night? Set the schedule to look at the hall and bedroom when deciding to come on.
The main reason I bought this was the auto switch between heat/cool and the fan circulate mode. I hate having to babysit the thermostat on freezing nights and hot days. The Auto switching is great.
The auto circulate fan setting is great. It will circulate air about twenty minutes an hour just using the fan to keep the house at a good temperature so it doesn't have hot and cold spots on those times when you are on the edge of the temperature range. I use it for the night.
This thermostat is not the most attractive, but I would recommend it. The only issue you may have is that the thermostat always seems to be back lit. Not sure if that is adjustable, but I love it because it acts as a soft light in the middle of the night for guests on the way to the bathroom.
Great product.

J'ai contacté le soutien technique d'honeywell home par téléphone et par messagerie instantané. Réponse rapide et très courtois et ils ne niaisent pas avec les détails d'usage. Cependant ils n'ont pas été en mesure de trouver le problème et il m'ont suggérer d'effectuer un retour/échange.
Dans une ultime tentative de dernier recours, j'ai effectuer une 4e fois une remise a l'état d'usine et cette fois j'ai choisi l'anglais comme language de configuration. Je ne sais pas si c'est vraiment ce qui a fait fonctionné le couplage avec mon application, mais cette fois ça fonctionné donc si vous avez le même problème que moi essayez ça.
