I use this control in my holiday home. It replaces the old room thermostat where I could mechanically set the temperature for the whole flat.
With the Netamo product, I can set the temperature from my home via my mobile phone so that the room is heated when we arrive at the flat.

Here's what I don't understand about the product. The Netatmo website doesn't give me any precise clues about it either.
Is the thermostat intended to replace the controller for underfloor heating per room, for example? With a potential-free switchover contact?
Or is it intended to work together with a Netatmo heating controller per room, in which the room temperature can be monitored more precisely? If yes, then this is a relatively expensive undertaking to properly equip, for example, an EFH with 6 rooms.
Thank you for all the replies.
If I have, say, 6 rooms with radiators. And replace the 6 old controllers with the new Netatmo controllers, which have an integrated temperature sensor, then the temperature measurement in the room is inaccurate because I have too little distance to the radiator when measuring the temperature. The results cannot be physically correct.
Therefore, theoretically I would have to place a thermostat in a neutral place in the room so that the correct room temperature can be measured.
The MAX! heating system is designed like this... One window contact per room, one controller per radiator and one thermostat that tells me the exact room temperature. The installation has saved me about CHF 600 per year in heating costs. I was able to measure this during the season with the neighbours who did not use a heating control system. But the system is hopelessly outdated. At the time, however, it was the best in terms of cost-benefit ratio.
I just don't trust the temperature measurement when it is measured directly at the radiator. I also wonder how Netatmo determines whether the window is open. Correctly, you would have to equip each room with a thermostat so that you can measure the unadulterated room temperature. And the thermostat is expensive, in my opinion. This means that with 6 rooms (with 6 thermostats) I will probably only have paid off the installation after 4 years at the earliest. And a lot can happen in 4 years in terms of development. That's why I wonder whether another product, such as Homematic IP, would not be a better solution.
Because Netatmo actually has window contacts, for example, but they are not used to control the energy balance, which raises a few question marks for me.
I understand that Netatmo offers an elegant and intuitive operation, but I doubt that this solution saves the maximum amount of energy.
What does Galaxus think about this topic?
The thermostat is powered by batteries. You will find the receiver in the same packaging. This is supplied with 230 volts and has potential-free contacts. You connect the potential-free contacts to the heating. This is where the two wires for the thermostat contacts are connected. This ensures that the heating is controlled and switched off by radio. Of course, you must first check whether your heating control has a thermostat contact. In the six rooms with underfloor heating, you must connect six battery-operated controllers. I can't tell you which ones, because I had radiators. And I connected them directly to the radiators. Then all the devices have to be registered with the thermostat via the software app. When everything is registered, you can assign a name to each controller. You can set up each room as you like and control it via the software or the app. You can control everything centrally on the thermostat. Like global temperature or I leave the house, etc. You can place the thermostat on the table or mount it on the wall. You can control the whole system remotely. So if you are on holiday you can switch on the heating from the hotel the day before. Greetings
