Curious about your SDR meter monitoring. Any links or description of how that works? Would love to monitor my electric and water without using the energy company's devices.

I didn't do any actual hard work. I just used rtl-amr, which was super-easy to grab, compile, and use.

http://bemasher.net/rtlamr/signal.html has information on how it works, but you don't need to do/know anything about the protocol to get it to work.
