Wireless lighting controller for a lighting control system

A wireless lighting control device, comprising:

• a housing member;
• a radio module housed within the housing member;
• a sensor housed within the housing member;
• a power switch operatively coupled to the radio module and the sensor, the power switch user configurable to operate in a first mode, wherein the power switch provides electrical power in response to a signal received from the radio module and does not provide electrical power in response to a signal received from the sensor, and a second mode, wherein the power switch provides electrical power in response to a signal received from the sensor and does not provide electrical power in response to a signal received from the radio module.

A wireless lighting control system, comprising:

• a server connected to a wide area network and having control software for configuring, monitoring, and controlling lighting devices at a site;
• a wireless gateway located at the site and including a transceiver to communicate with the server and a communications module to communicate with the lighting devices via a wireless mesh network;
• and,
• at least a first and second wireless device each having:
• a radio module for data communications via the wireless mesh network;
• an output module to control a light fixture;
• and,
• a sensor to detect an event;
• and,
• wherein the first wireless device is configured to send a data message via the wireless mesh network upon the sensor of the first wireless device detecting the event, and the second wireless device is configured to operate a connected light fixture upon receiving the data message via the wireless mesh network.
