If you document this somewhere I'd love to read about it! I took the approach of sniffing the packets between the radio and mcu on the bridge board, got most of the way into reverse engineering that, then helped build this instead:

But I always wanted to finish pulling flume data to home assistant, without the cloud.

I am planning a write up once I get it working. I'd be happy to share.

My setup is a logic analyzer tap on the SPI bus between 8266 and the RFM69 on the bridge device to log raw traffic, and my secondary RX (ESP32 + RFM69) for over-the-air traffic.

Also, I have a gas meter sensor based on your work half-built on my workbench. I plan to set that up once I finish my Flume distraction. Great work, thank you!

I'd done exactly the same, though my efforts were pre-Claude. If you want my logs/data, username at gmail.
