Reading Electric Meters with RTL-SDR and HomeAssistant

Over on his blog Jeff Sandberg has posted a writeup detailing how he combined RTL-SDR, rtl_amr, and HomeAssistant to decode wireless data from his Itron power meter, and create useful graphs showing his US home's power usage.

In the post, Jeff explains how he uses an RTL-SDR Blog V4, HomeAssistant, EMQX, and rtl_amr to receive and plot the data. The RTL-SDR and rtl_amr software receives and decodes the wireless Itron electricity meter data packets, and then EQTT passes the data to HomeAssistant for logging and plotting. Jeff also notes how he used NodeRed to correctly automate the summer and winter tariff price changes.

Finally, in an update to the post Jeff mentions that he was also able to receive and log data from his gas meter.
