Help with Grafana/Prometheus and SRNE inverter

[Dmichel123]

I'm trying to monitor my SRNE hybrid inverter with a Raspberry Pi. I think this is what I need, or at least a very good start:

GitHub - shakthisachintha/SRNE-Hybrid-Inverter-Monitor: Python based remote monitoring and controlling system for SRNE hybrid inverters.

Python based remote monitoring and controlling system for SRNE hybrid inverters. - shakthisachintha/SRNE-Hybrid-Inverter-Monitor

github.com

I've gotten as far as running the main.py script, but I don't think everything is fully functional yet. I am able to open Grafana and see graphs/charts of my Raspberry Pi stats, but unsure how to get the SRNE stats into Grafana. This main.py script appears to be using FastAPI and outputting to port 5004, but I'm not able to access that in my browser.

Any help would be greatly appreciated.

Can somebody show me how to change this script to use Prometheus instead of FastAPI/Uvicorn or walk me through making this work as is?

Everything I try to attempt to get FastAPI info into Prometheus seems to break both.

I broke down and bought Solar Assistant. It is useless. I can only change like two settings and can't turn the inverter on/off.

if you give me some time i can add support for it to my project. or if your in a rush you can implement it. not too hard to make the config/csv files.

assuming SRNE's v1.7 v3.9 modbus protocol is the correct one.

implemented in v1.1.2 branch. untested.

be aware the write functionality is still in it's infancy for this project.
