Ecobee’s thermostat is a simple, black slab of glass that sits on the wall, begging for less attention than the Nest. When the display behind the black slab comes to life, you’ve got a touchscreen panel that you can work to adjust the temperature and humidity in your room. a slider allows you to calibrate the temperature to perfection, while the temperature itself is displayed to the left of the slider in a large font that’s light yet easy to read.
