The hue bridge 2.0 is a small square box that is located somewhere in the home. It is powered by an external power adaptor. One of the functions is to bridge between wired Ethernet (or WiFi) and RF ZigBee network. The Ethernet interface is a RJ45 connector to support 10/100‐TX Ethernet networks. The RF antennas for the ZigBee and WiFi are internally. There are some LEDs on the box to provide user feedback.
