Abstract: Disclosed are systems and methods for adjusting environmental conditions based on automatically and manually generated requests. A commissioned unit comprising at least one IP luminaire (140, 150), transmits a signal comprising one or more identification codes. The signal may be, for example, a coded light signal.
