In addition to a ‘normal’ smart thermostat, Netatmo also has a smart modulating thermostat that supports OpenTherm.

In terms of design, they look the same: a white square box, which you can ‘decorate’ with a strip in four colours. In the middle is a display with the desired/set temperature at the top and the real temperature at the bottom. You can manually operate this thermostat by briefly pressing the top and bottom for half a degree more or less. What is striking about the Netatmo is that you can also place it anywhere wirelessly in addition to the wall; You do connect the relay wired to power via the boiler.
The well-arranged Home + Control app from parent company Legrand (the app is called Control) has the settings Comfort† eco and Night which you can expand with whatever you want. It also works with Apple Homekit. Netatmo also has a Smart Radiator Tap with Open Window Detection: if it detects an open window, it switches off the heating in the room to prevent energy wastage.
