Description: Just a blog
I recently got an electric car and wanted something more interactive to look at given my electricity usage. I know my power meter transmits usage data for PG&E to use and wanted to attempt to capture that data myself, rendering it for my usage. I didn't succeed, and I'm kind of stuck on what to try next, but this is where I left things.
I think my SmartMeter is this model or at least uses that module for transmitting data to PG&E.
I bought a NUC Linux system and a couple of software-defined radio dongles. The first SDR I bought didn't have the frequency range that my SmartMeter supports, so I bought another one with a wider frequency range. It turns out the second one I bought doesn't go quite high enough to capture the upper-frequency range that it supposedly uses. The SmartMeter seems to use frequency ranges 902.3–926.9 MHz and 2.4058–2.4809 GHz, and the second SDR I bought goes up to somewhere around 2.1 GHz.
