Not OP, but in my jurisdiction the smart power meters broadcast consumption as SCM at 900MHz. rtlamr https://github.com/bemasher/rtlamr https://github.com/bemasher/rtlamr does a good job of receiving and decoding those broadcasts using a cheap SDR. My local water utility also broadcasts consumption as SCM+, also 900MHz. I'm able to grab both with the single SDR.
