I really haven't seen a worse room thermostat and the one star is way too much, it doesn't connect to anything and when after a long time I saw the new app which is laughable, first of all it's not what it advertises, the thermostat's temperature is 3 degrees above reality, I will ask for my money back because this is outright theft. Well, today 10/2/25 communication with Legrand only has all the functions on Android, they gave an order and I returned them to the store where I had bought them

I have had it for 2 years and the WiFi has never worked. I made 2 replacements in case there was a problem with the device. I spoke on the phone with a technician from Legrand. NOTHING.
I searched the network to see if the problem was with my router and needed to open some ports (I did that too). NOTHING.
Given that 2 air conditioners (Toyotomi & Inventor), a security camera (Skycam), and a security lock (Somfy) work seamlessly via WiFi in the house, Legrand's inability to provide a functional and reliable product is disappointing.

It never worked. I asked for help from the company's service. They sent me a diagram exactly as I had connected it and then nothing. Money wasted.

Very nice touch screen interface. I operate it with the apple home app. It connected very easily and I haven't encountered any issues with the wifi connectivity. Minus one star because there is no way to completely close the interface (or I haven't found it yet).

I got it for my vacation home so that I can monitor the temperature of the house and turn on the heating before we arrive and find it warm. It is very easy to use and very beautiful. Initially, I had the problem with the disconnections that are mentioned in other comments, but since I changed the location of the router in the house to ensure that the thermostat will have a good signal, I did not encounter any problem. If the internet or WiFi connection is temporarily lost, there is no need to reinstall the connection between the app and the thermostat, but it automatically reconnects (or manually refreshes from the mobile app) when the internet connection via WiFi is restored. The thermostat records and stores the temperature and humidity every 3 hours, and I can see the changes from the app in the form of a graph. The home+ app is great.

Difficult in programming, starts whenever it wants, and changes the temperature on its own, unacceptable for its price.

Very reliable and useful device! The installation is not difficult, but because it involves 220V power cables (a voltage that doesn't even drop if you turn off the main power of the house in case we are talking about an apartment building with a central boiler), I consider it necessary to have an electrician complete it. The connection to wifi through the mobile application is very easy and its use is simple - you don't even need instructions, the application guides you step by step. The next step of installation is the netatmo thermostatic valves, so that you can have the desired temperature in every room of the house.

Like all legrand products, this one also has rudimentary documentation. There is no comparison between the previous version of bticino and the newer home+control version of legrand. The new version has a very simplistic interface that only allows for very basic settings. Those who have used the bticino smarther, which looks identical to the legrand smarther, will be disappointed. a) Installation is relatively simple, but requires some knowledge. b) The application is unacceptably simple. c) On-site use is okay. If you don't have any other legrand products in your home+control, it's better to go for another solution.
