For me, the Sensocomfort is hanging in the heating cellar. It's good for my fitness, but I'm actually lazy...
The question is whether the heating cellar is an optimal place for the Sensocomfort.
The device measures the set "desired temperature" as a reference in the respective room. Since presumably a different temperature prevails in the heating cellar than in the rest of the house, the location is actually suboptimal.
On the other hand, you certainly do the thermal balancing room by room, so that the set desired temperature only represents a relative value.
As far as radio is concerned, I simply recommend retrofitting the "Vaillant Internet module sensoNET VR 921" for around 200 EUR.
Then you can control everything from the app and have further overview and consumption statistics .....
