Water meter HRF-C-G2 868 MHz

Hello everyone,
Did anyone ever integrated Home Assistant with the water meter HRF-C-G2? It works at 868 MHz. Would that be possible with the CC1101 for instance? I am not sure how often this water counter sends data and if we can pull the data as often as we want to. I also don’t know whether it’s a protected signal or if it is easy to read.
Thanks for your help!
