great piece of work but i got some questions
I have several sensors available for use and couple of them are a negative input when i’m using power or are negative when i’m injecting my surplus of solar power to the grid, is there a way to also display the injection?
I tried to adapt for the negative part myself but i must be like missing something somewhere.
besides that is it possible to work from both sides of the strip? Because I also have a batterysystem connected to my solar inverter and it would be nice to display the state of charge also…
So if i got a strip of 100 leds if i could use like 50 for power usage/injection and the other 50 for displaying the battery status.
This is what i got for the moment:
