Thermostat UI concept for Android using Material Design principles
Gotta be thumb friendly and for left and right handed.
Do something different than the usual circular interfaces.
Temperature is a scale, and doesn't/shouldn't be represented in a circle.
Dials are circular, but you only need a small part of it, a scrolling area.
Max. and min. are determined by unit, don't put values onto the dial.
I will also make a darker version and maybe one with more color.
