Control an accessory with multiple features
Accessories with multiple features are controlled by one accessory tile. For example, if you have a ceiling fan with a built-in light, you can control the speed of the fan and the brightness of the light from the same tile. Sensors are grouped by accessory categories at the top of the screen.
