I was thinking it will be great if we have have percentage indicator 0-100 % instead of 0-1023 for gauge widget, as to measure water tank level.
This is already fully implemented. Please read up a bit more on how to adjust display widgets.
NOTE the Min/Max settings of 0-100
There is also a built in Data Mapping mode,
But I usually find the Arduino map() command as more precise.
Thanks a lot, really great
