Description

The "smart" thermostat with Wi-Fi technology, along with the special Home + Control app, allows you to set and monitor the temperature in your home with precision. 

The Home + Control app requires the latest version for iPhone, iPad, iPod, and for Android version 5.0 or later. 

Programming is easy and simple using the app. 

It features a touch surface where the temperature and humidity level of the space are displayed, and from where the desired temperature can be set and the Boost function can be activated: turning on heating or cooling for a period (30, 60, or 90 minutes) regardless of the room temperature or the selected program.

Through the app, the following features are available:

  • Away function if you are going to be away from home for a short period (temperature 120 C for heating operation or completely off for cooling operation) regardless of the selected program
  • Frost-guard function if you are going to be away from home for a long period in winter (safety temperature 70 C), regardless of the selected program
  • display on the screen of the room temperature and the operating time of the heating/cooling system


  • Compatible with any temperature management system (heating, ventilation, air conditioning) that operates with an ON/OFF command, such as a local electric valve in an autonomous heating installation.
  • Compatible with Netatmo Additional Smart Radiator Valves
  • Can be controlled with voice assistants Google Assistant, Siri, and Alexa (currently, voice assistants only operate in English)

    This review is about a variation of the product

    The best choice for a thermostat. Don't waste your time with cheap alternatives. Remote control and in combination with the electric valves, it will simply save you a lot of money. The Legrand app is user-friendly, and after a certain point, once it learns the energy inertia of your home (Heating - losses), it manages it so you have absolute thermal comfort when you need it. The price is a bit high overall, but it's worth the money.

    Update 1/5/2024
    I noticed that the humidity measurement was not accurate. I checked it with several smart thermometers and with the dehumidifier. You don't expect it to have the same measurement because it depends on the sensor's position within the device, but the deviation was over 20%. I contacted Legrand and was served promptly. A case number was assigned, and ultimately, a replacement was made at no cost to me. It was a hassle to remove and install, but it happens. The new thermostat has a 5% deviation, which I consider acceptable. Many times it slips your mind because the thermostat permanently shows the temperature, and you have to slide the screen to see the humidity percentage or check through the app, but it's not insignificant and you need to pay attention to it because it affects how the heating algorithm learns.

    Very good, excellent thermostat I can say.
    WIFI connection is almost easy. You need to know about electrical connections.
    The application has many capabilities, it has never disconnected from the network in the 2 years I have had it.

    Disappointment despite the enormous cost, the thermostat disconnects for no reason and to reconnect it to the network, it requires setting up again

    -The thermostat was installed in a condensing gas boiler!! In order to connect it to a gas boiler, the thermostat must not send power to the boiler (Cold contact)!!
    The thermostat has a constant power supply because it is Smart, but it does not send power to the boiler if you make a cold contact connection.
    The thermostat has 4-5 connection modes, connection to a cooling system, underfloor heating, etc. All modes are highlighted in the manual. You can do it yourself if you know how, otherwise call an electrician because if power goes to the boiler, you will burn it. Also, it requires a stable power supply, otherwise the Wi-Fi will be cut off, as many say they have issues with other models due to incorrect power connection.

    -The connection with the application is easy.
    -The connection to Google Home needs to be done a bit strangely when searching to link the device, from the set up write Netatmo in the search and it is the first option that says Legrand - Netatmo - Bticino, if you write legrand it shows 100 others that are not compatible.

    -It is very small because it is recessed and what protrudes is as thick as a switch and has a nice design.
    The part that goes into the wall is as big as a socket.

    -I have had it for 2 weeks now and I am very satisfied, the legrand home application programmed it based on my schedule and it goes up and down on its own according to the time and temperature I have set. With Google, I can control it whenever I want and I can know the temperature at any time. Now, whether I will have savings up to 37% remains to be seen, as the person who maintains my boiler told me, they make a difference, but you will see it more in a condensing boiler, although it won't be a huge difference. We shall see!
    I highly recommend it.

    9/1/2022 update:
    An update about the thermostat.
    -I am very satisfied with the thermostat.
    -I have seen a reduction in the bill of about 10%-15%.
    -I don't have any issues with disconnections, only if the internet is cut off due to the router and essentially the house doesn't have internet.
    -Also, if the boiler shuts down for any reason and the temperature of the house doesn't reach what the thermostat says, you receive an email saying that there is a problem and the temperature is not what it should be, which is very useful as due to a difference in a radiator, the pressure drops for me and I have to go and increase the pressure of the boiler from time to time.

    So, I continue to recommend it.
