I have solar panels that are over 10 years old and I wanted to check if performance is degrading

I used an Open Source tool (SBFSpot) to grab some data from the inverter over bluetooth and so it has to be physically near the inverter and runs on a Raspberry Pi

So far so good - I have nice graphs at https://pvoutput.org

But I really wanted grafana graphs it is such a powerful dataviz tool

For that I needed to get the data to Prometheus
