50 * This sensor Thing doesn't establish any connections, that is done by the bridge Thing.
52 * It waits for the bridge to come online, grab the websocket connection and bridge configuration
53 * and registers to the websocket connection as a listener.
55 * A REST API call is made to get the initial sensor state.
57 * Every sensor and switch is supported by this Thing, because a unified state is kept
58 * in {@link #sensorState}. Every field that got received by the REST API for this specific
59 * sensor is published to the framework.
