Only jump to Sensor view during charging if sensors are connected:
In the past it could happen that the charger view was replaced by the sensor view which was not displaying values because no sensors were connected => no added value in performing the switch. In the new version the automatic jump to the sensor view will only be performed if sennsors are connected.
