In my home office, I am using the Leviton Occupancy Detector. The issue with this Leviton Detector is it will turn off within a certain amount time when there is no motion detected even though I am in the same room and sitting my desk. I need occupancy detector that will detect fine movement like typing. I am in the line of sight of the switch but off to the side of the switch. Lutron suggested either a Wall Switch Radio Powr Savr wireless wall – mounted Occupancy/Vacancy Sensor (LRF2-OWLB-P) or Lutron Maestro Motion Sensor switch (MS-OPS2). Which one should I buy with my current setup as explained? Thank you!!!
