Controlling several luminaire groups with one sensor is possible by using scenes. 

For example, if there are two luminaire groups and one sensor in a space, you can set different dimming levels for both groups by adjusting them in the scene table with following steps:

1. Create a space with two groups and one sensor

2. Add a scene with a default dimming level in the scene table

3. For the created scene, set different dimming levels for different groups

4. Configure the sensor to trigger the scene.
