Easy install - wiring was straight forward - works well with the add on remotes. able to get a little better temp balance across the house now. Not as "polished" as the nest, but not as expensive either and works just as well (I had a Gen 1 nest)
The thermostat works fine and was easy to install. However the advertisements state that if you don't have a c-wire you can use the included adapter, but that is true only if you have a cooling and heating system. Since I only have heat, I had to purchase a different adapter. Also, the software is poorly designed. There is no user manual for the software and the one for the thermostat itself (must be downloaded) is minimal and not at all adequate.
I like this thermostat. Very easy to set up on thermostat or on app. I gave it 4 stars because I bought the one with the sensor and it's a bit confusing to me to get the correct temp. We have a 2 story townhouse and the top is hot and the bottom is freezing. Still working on that issue.
After doing a lot of research, I decided on the T9. The remote sensors and ability to set temperature by the rooms that are occupied were the deciding factors. We are using those features along with the geofencing. All 3 features work very well and allow for customization that others don’t offer. So far, 2 months in, I am very happy with the thermostat. My only critic is only an issue if the thermostat is near your bedroom. When the heat/cool turns on the thermostat makes a click noise (quietly) and the background light goes on. If you are a light sleeper, it can be an issue. I wish you could turn off the background light at night.
It is a good thermostat just that, with a lot of fancy feature that are a waste. Terrible customer support, never answer email and one hour to get connect with anybody if you are lucky.
This thermostat was easy to install for the average skilled DIYer. The instructions were detailed and it came with a C-wire adapter for older systems.
The App easily connected to my WiFi an stepped me through the initial setup.
I then added two remote sensors to see if it really could work balancing the temperature in a single zone bi-level home. The thermostat is on the main level in the living room and dining room area, the lowest activity area in the home and the kitchen is in a separate room on the same level.
The bedrooms are up a 1/2 level and are always 3 - 4 degrees warmer than the main level and down a 1/2 level is always 3 - 4 cooler during winter months. I set up a schedule to give priority to the main thermostat during the day, the lower level in the evening and the upper level during sleep periods. I used to keep the blower running 24 x 7 to keep the air circulating, with this device I set it to recirculate and it now runs intermittently, between heat / cool cycles.
It took nearly 2 weeks for the system to learn our activity but now it keeps all levels at nearly the same temperature. It also took us 2 weeks to learn to stop looking at the thermostat display, as it displays the temp of the prioritized room and not necessarily the temperature at the thermostat.
We're retired and home all day, so we're not going to save a lot of energy with the Away setting (we deleted it), however we will save on our most expensive energy cost, electricity, without the blower running 24 x 7 x 365.
