Time to update this topic with current status and code.
This system basically monitors a simple charge controller that is fed from a couple of solar panels wired in parallel. The App sits on my treadmill and “runs” 
24/7 Giving me updates on charge rate, battery voltage, outside temperature & humidity (with a bridge feed to another bench-top project with indoor temp & humidity monitoring) and a history graph of the whole thing so i can look back a recollect how sunny but cold that there day was 
And since I also mounted a couple of 1.5 meter RGB strips on the solar panels - One facing outward and the other, wired in parallel, facing upwards to reflect on the windshield and thus inside. I figured I can have a single Wemos D1 Miini, doing multi-duty by controlling them as as well. It is running a FastLED scrolling demo, also 24/7.
I used to have the batteries power the LED strips, but since I doubled them up and let them run all night… these little batterys don’t have the holding power… so for now the LEDs are powered via as AC adapter.
