I just got an Elster V210P water meter with 868MHz TPR6 RF module installed at my house.

I am developing my own home automation system (in C#) and was wondering if I can read values from this water meter somehow.

I found out that the RF module uses the Wavenis protocol but so far I was not able to find much more information.

Do you think this would be possible? Has anyone done this already?

If yes, what hardware (868MHz transceiver?) would I need and where can I get this from?
Ideally I would want to connect this to an Arduino or similar but I'm open to any suggestions at this point.

Any pointers where to start on the software side?
