A lot of those are not encrypted and can be read with a cheap sdr dongle.

    I have a smart meter that allows grid controllers to remotely charge and discharge my battery to smooth out high demand peaks (I earn money from it) but I haven't been able to record a coherent bitstream from it with my SDR yet. I assume it's encrypted and/or proprietary data.

    From what im told, the transmitters lie dormant most of the time (at least for gas). Only when they receive a signal do they send a signal, except when they are activated by a technician. When activated, they broadcast a signal to reach either another device on the network, or a reciever like the one in op's pic.
