Sensors To Turn On Exterior Lights?

Hi, I have a bunch of exterior lights controlled by RRD-6CL dimmers on a RadioRA2 system. I was hoping to install some sensors do detect presence and turn on the lights to, say, 30%. Are the occupancy sensors a good approach, or is it better to have the sensors as part of an alarm system and then integrated into the RadioRA2?

Thanks!

The RadioRA2 battery powered sensors are not rated for external use. If the alarm system is in place, have the existing sensors trigger a scene via phantom button on the main repeater (if integrated) or have the alarm panel trigger send a CCO to input 1 or 2 on a VCRX, using the input as a maintained contact. When the alarm sensors no longer detect movement, the CCO will open/release and the scene will turn off.

Outdoor sensors would be a nice add
