the class ControllerProtocol method onPollingResponse.

/**
 * Polling request should return three different responses :
 * <ul>
 * <li>OK (200) : new values are available for at least one of the sensor provided in queryParam</li>
 * <li>TIMEOUT (408) : during the last 60 seconds following the start of the request, none of the sensors have new values</li>
 * <li>Others : error</li>
 * </ul>
 * <p>
 * In every case, we should start a new polling request directly. Only the 200 response induce an update of every linked attribute having a sensor
 * status updated.
