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.

Over on her YouTube channel SignalsEverywhere, Sarah has uploaded her latest video showing how it is possible to monitor Itron ERT smart meters on an Android device.  Smart meters are used to wirelessly monitor the usage of residential utilities such as water, gas, and electricity. With an RTL-SDR and some decoding software, it is possible to monitor the data coming from your own and your neighbours meters (at least for certain brands of meter).

In her video, Sarah shows how she compiled the rtl_amr decoder software for Android, and created her own Android app called "AndAMR" for displaying the data decoded by rtl_amr. The rest of the video shows how to set up and use the app.
