Home Assistant adds a fan control for generation-two-and-later Shelly devices that expose a fan component. It can turn the fan on or off, choose its speed as a percentage, or return control to the device’s automatic mode.
Changing power or speed selects Manual mode. Switching from Auto to Manual preserves the current output until another command changes it. The accompanying guide also brings together the fan’s boost control and its humidity, light-level and energy readings; boost is available in Auto mode.
