In fact, it is just a box that manages the triggering of the heating by pilot wire, Comfort Mode / Normal mode.
Then it is the heating temperature sensor which manages whether it should heat or not.
The system allows you to heat a little more before getting up (preferably off during off-peak hours) and in the evening before arriving.

there are currently a multitude of woefully incompatible home automation buses ... if I want to make equipment of this kind I have no other solution than to make my own bus ... one more
Personally I would rather look for an arduino / Raspberry PI mix.
Arduino for all that is probe.
Raspberry for info gathering.
After, either you can pass cables and you manage everything by wire. (this is probably the least expensive solution)
Either you manage in RF433 short range, RF868 probably more important range, Bluetooth short range, Wifi, Zigbee (can be quite expensive)
Personally, I made myself a connected weather station, I would have to publish all my work on GitHub one day or I would be motivated.
I can retrieve information from an Optio probe using RF433 (low-end weather station external module).
But the range is around 5m ...
