DECT Control of Thermostatic Radiator Valves

[remoticz]

Since heating control with Danfoss Zwave valves is my major application, I got interested in the Eurotronic Dect controlled Comet valves. I did notice that the next Fritz.box modem firmware is going to support these devices.
Unlike these RaspberryPi toy devices, awkward Danfoss Z-Wave valves, Fritz boxes have proven over many years to be rock solid. So it seems an interesting more robust alternative to me.
There are some early comments on the Conrad site. It seems this service is only available on Fritzboxes for the German market at the moment.
Anyone here who tried it?
