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