Abstract: A diagnostic apparatus (101) for diagnosing faults within a lighting system comprising at least one luminaire (121), and at least one presence sensor (123, 151) configured to control the operation of at least one luminaire (121) when an object is within the presence sensor (123, 151) sensing range, the diagnostic apparatus (101) comprising: a user input (103) configured to receive at least one input to control the at least one luminaire (121); and a fault determiner (221) configured to determine at least one lighting system fault based on the at least one input and wherein an object is within the sensing range of a presence sensor (123, 151) expected to be associated with the at least one luminaire (121); and a fault reporter (223) configured to generate at least one fault report based on the determined at least one lighting system fault.

Abstract: Lighting units, lighting systems, and methods are described herein for automatic and decentralized commissioning of a replacement lighting unit (140, 150, 250). In various embodiments, a replacement lighting unit may receive, from one or more remote lighting units over one or more communication networks, one or more identifiers associated with the one or more remote lighting units. The replacement lighting unit may also receive, from at least one of the one or more remote lighting units over the one or more communication networks, the lighting operation parameters associated with an inoperative lighting unit. The replacement lighting unit may then selectively energize one or more light sources (258) associated with the replacement lighting unit to emit light having one or more properties indicated in the lighting operation parameters associated with the inoperative lighting unit.
