En general funcionan bien, y la app ayuda a su manejo a distancia, pero después de un año tienen fallas, y es imposible encontrar datos de servicio para repara o aplicar garantía. y ya me empezó a fallar el segundo termostato

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.

UPDATE- after using the app more, I've decided to upgrade my rating on the app to a B+. The connection issues haven't been a problem, and it is quite capable and easy to use regardless of how it felt during installation. I THINK that when I'm on the same wifi connection as the thermostat that the app doesn't have to "phone home" to get info and update settings, which is a bonus.Hardware still running like a champ, love it.--------------The instructions seem pretty thorough. They cover multiple scenarios to make sure that you understand how to get it working. In my case, I had a four wire connection to the HVAC with no C-wire. The system includes an "adapter" that you connect to the HVAC panel, then re-connect your thermostat wire to it, and then finally connect the thermostat. This process gives you a C-wire at the thermostat so the unit has power. Better and prettier but more complicated than a dedicated wall-wart transformer. I've not tried the heater yet (it's August!) but the A/C side is working flawlessly. Installation took about 45 minutes to do everything but the wire pre-labeling, and it worked the first time. Controlling the unit from the panel is easy. Connected to the remote sensor fine. Can set the time and schedule, use motion detection to determine active room, everything it's supposed to do. Scheduling options are great. BTW, the main unit and the remote sensor report humidity too! All good.And then, I turned on the wifi. First thing it did was reset the time, I think to UTC. Then you have to download/install the app (ok), register a new account with Honeywell (ok), and create a location (e.g. "home." Possible to use the app to control multiple thermostats at different locations.) NOTE: If you don't let your phone or tablet use location data, you apparently can't create a location and the app just spins, but the app doesn't tell you that. Then connect the app to your thermostat. Honeywell emails your account an activation code that you then enter at the thermostat (somewhere around here it figured out my timezone and fixed the clock). Eventually it's all set up and your problems are over, right? Nope. I'll be poking through the app and at random times it'll claim I have no internet, but I'm sitting right next to my wifi and using internet on other devices. Having said all that, the app does function, controls the HVAC fine, lets me do what I need to do. It's not hard to understand or use, but the drops might be really annoying if they got in the way. I've not tried geofence and don't plan to, but that might be a good app test. Also the app is designed to work with a lot of devices. Thermostats, security systems, and more. Great on one hand but possibly causing loss of focus. So, overall:Hardware: A+Instructions, ease of installation: A+Honeywell App: C+Most desired improvements: Fix the internet connection issue. Offer more options for programming, like "if there is a difference of degrees between sensors, turn on the fan," or allow the system to run based on humidity/heat index.

Very happy with product, it works as expected and was easy to install.

In the catalogue it is mention that thermostat will work only on 24 V

This thermostat is not able to control the fan speed if the AC unit. Two options only: either off or full speed. Very inconvenient.
