64 * This light thing doesn't establish any connections, that is done by the bridge Thing.
66 * It waits for the bridge to come online, grab the websocket connection and bridge configuration
67 * and registers to the websocket connection as a listener.
69 * A REST API call is made to get the initial light/rollershutter state.
71 * Every light and rollershutter is supported by this Thing, because a unified state is kept
72 * in {@link #lightStateCache}. Every field that got received by the REST API for this specific
73 * sensor is published to the framework.
