Abstract
Some embodiments are directed to a verification device (200) arranged to verify based on incomplete information. The verification device is arranged to compute an energy consumption estimate for one or more luminaires from occupancy data, and compare it to received energy consumption data. A signal is transmitted if a lack of dependency is found in the lighting system with other factors than occupancy.

A verification device for verifying a lighting system comprising multiple luminaires, light sensors and occupancy sensors, the lighting system being configured to control said multiple luminaires at least partly in response to said occupancy sensors and partly in response to said light sensors, the verification device comprising:
- a communication interface arranged to receive:
- energy consumption data indicating energy consumption of one or more of the luminaires,
- occupancy data indicating detected occupancy of one or more occupancy sensors, at least one of the luminaires being controlled dependent upon the one or more occupancy sensors,
- wherein the occupancy data and the energy consumption data correspond to a same time period, said time period being during daytime;
- a processor circuit configured to:
- compute an energy consumption estimate for the one or more luminaires from the occupancy data,
- compare the energy consumption estimate to the received energy consumption data and detect if a conformance therebetween is within a threshold, and if so
- transmit a signal indicating a lack of dependency of the lighting system on light sensor measurements of the light sensors.
A verification method for a lighting system, said lighting system comprising multiple luminaires, light sensors and occupancy sensors, the lighting system being configured to control said multiple luminaires at least partly in response to said occupancy sensors and partly in response to said light sensors, the method comprising:
- receiving energy consumption data indicating energy consumption of one or more of the luminaires, and receiving occupancy data indicating detected occupancy of one or more occupancy sensors, at least one of the luminaires being controlled dependent upon the one or more occupancy sensors, wherein the occupancy data and the energy consumption data correspond to a same time period, said time period being during daytime;
- computing an energy consumption estimate for the one or more luminaires from the occupancy data,
- comparing the energy consumption estimate to the received energy consumption data and detect if a conformance therebetween is within a threshold, and if so
- transmitting a signal indicating a lack of dependency of the lighting system on light sensor measurements of the light sensors.
