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