I have a sma stp6000tl-20
Inverter that I'm reading out true modbus
Now I see that sma also makes pv voltage and dc current available on modbus
Is there a way to read those and make a graph on venus os ?
Reason I'm intrested is because I'm using 2nd hand pannels that had a 30% failure rate in 10 years at the last owners installation (lots of shade)
A dc voltage and current graph will give me an easier way see problems with my system
Tldr: want to read more modbus data and add to victron portal
