A lighting apparatus connected to a network includes a light source for emitting light. A controller controls operation of the light source in response to an external control signal. A non-contact sensor detects a non-contact signal and generates a reset signal in response to detecting the non-contact signal. A communication interface communicatively connects the lighting apparatus to a wireless network to receive the external control signal from a remote apparatus via the wireless network and disconnects the lighting apparatus from the wireless network in response to receiving the reset signal from the non-contact sensor.
