I got my second hand FLM V2 I think and I know basics of Raspberry Pi and Node-red.
My setup is this:
A. 1 clamp is on the internal consumption
B. 1 clamp is on the first solar panel convertor
C. 1 clamp is on the second solar panel convertor
In Node-red I did read the FLM with MQTT and it works well.
I made 3 gauges.
1 total internal consumption.
1 sum of the 2 solar convertors
1 Deduction of total consumption - solar convertors.
Now I would like to store the daily data into node-red and here my knowledge stops.
It needs to be with db I think.
Is there here somebody with a working Node-red Flow?
