Location independent lighting sensor system

1. A system for sensing luminaire properties and controlling a luminaire performance based on sensor readings of the luminaire, wherein the sensor readings are taken without regard to the location, distance or orientation of the sensor relative to the luminaire, comprising:

a dimming control configured to control the dimming of a luminaire;

at least one sensor configured to take a sensor reading of the luminaire;

13. The system of claim 1 , wherein the luminaire lifetime prediction relationship generated by the cloud server is generated by comparing a manufacturers' theoretical lumen degradation prediction graph to measurements taken by the at least one sensor.

14. A system for sensing properties of a device and controlling a performance of the device based on sensor readings of the device, wherein the sensor readings are taken without regard to the location, distance or orientation of the sensor relative to the device, comprising:
