Once you have at least one motion sensor in a room, you can pick the action the lights will execute when motion is detected.

ON

"ON" will turn on the lights if they were off, but also send them to their Rhythm if rhythms are enabled.
This is the action by default.

Brightness change

If the light was off, this will turn it on and apply the specified brightness level.
If the light was already on, then this will adjust the brightness to the specified level when motion is detected.
Note that some modes such as Night Light or Wake-up do not support brightness adjustment.

Light modes, colors and custom whites

You can also select the light mode, custom color or custom white of your choice, and apply a level of brightness if you want.
Note that tunable and dimmable white lights may not support color modes.
