If a Sensor (Desk, Huddle or Room) always shows as busy, you can do the “box-test”. With this test, you will see if the sensor or the environment of the sensor is the problem.
Remove the sensor and switch it off, after one minute switch the sensor on again, or reset it with a magnet. After a few seconds, the sensor will enter “detection check mode” and show you via the LED if it detects movements. If the sensor is green no movements are detected, if the light is red movements are detected.
For the “Box-Test” put the sensor in the “detection check mode” and place it in a small box:
If there are no movements, the LED should be green:
If you now put your hand in the box, the LED should switch to red:
If the LED is already red, without movements in or above the box, the sensor may could be broken. If so, open an RMA over the Portal.
