Very cool! Not long after I wrote this (and rfm69-elster), my city enabled encryption, rendering it useless. A couple years later they replaced our meters with Itron branded ones. I've since changed approach and am using an Emporia Vue for electric monitoring and a project called "AI on the edge" to read my water meter. I'm glad this was useful to you, enjoy! |

Hey @shaunhey thanks for a really cool project! I figured I should share with you my mods to it.
It can now read the total kWh reports my electrical meter chirps and I've added some notes in the readme showing how I relay the readings to my mqtt server (Home Assistant). With this, I get a new reading that matches the kWh number on the display of my meter every 4-6 hours (better resolution too, down to 1 Wh).
I'm using https://www.nooelec.com/store/sdr/sdr-receivers/nesdr-smart-sdr.html with it and I run it on my raspberry pi 5, very, very low CPU usage!
Just modding the ea_receiver code into also decoding my meter readings was not such a modular choice. This decoding stuff really deserves to be split out into a standalone executable.
