But are you aware of any non cloud based meters that just rely on the ADC of the module with I guess a voltage divider or a simple ic?
I saw the upgrade to fluke sprite_tm made and that was beautiful but that is an expensive (and far more accurate) approach.
Just hoping to be able to build a few cheap ones to monitor say 0-20vdc open a web page to see the values pushed in as plain text, maybe with a line graph.
Basically a basic and cheap version of that mooshimeter.
