    Excellent Product!
  

*by B***. on Reviewed in the United States on 30 March 2023*

I've purchased three of them now, and couldn't be happier.  Easy to install and works fantastic!

### ⭐⭐⭐⭐⭐ 







  
  
    Great to have the power to change settings from remote locations
  

*by A***R on Reviewed in the United States on 28 February 2024*

This thermostat works great. I have it installed in a vacation home that is 150 miles from home. It works great having the power to keep the temperature low when we are not using this house and then changing the temperature when we are traveling to the house. The house is nice and warm when we arrive.

### ⭐⭐⭐⭐ 







  
  
    So far unable to set up App
  

*by L***D on Reviewed in the United States on 26 March 2023*

Nice product and well thought out. Works well as a stand alone thermostat. I have been unable to connect this device to my mobile app which is important to me as a 2nd home that is occupied only part time. As a part of the setup process, the server that controls the app is supposed to send a confirmation email to your address in order to connect the app. This step never occurs. I have used different email addresses and reset the devices several times attempting registration. I have sent emails to the manufacturer and have thus far not received a response.Update: the local reseller worked hard to get me connected following several phone calls.I am now satisfied with this purchase and product.
