The controller-side wireless module communicates via a wireless communication protocol (e.g. Wi-Fi, Zigbee) to at least one device-side wireless module. Each device-side wireless module is connected to a DALI stream via a second two wire data bus to at least one DALI ballast (slave) which is connected to at least one lamp bank. Additional devices may be connected to the DALI stream.
