Abstract
It is presented a method for detecting a position of a barrier. The method is performed in a status monitor device and comprising the steps of: detecting a barrier position of the barrier using a first sensor, the barrier position indicating a degree of opening of the barrier; detecting when the barrier is in a closed position using a second sensor; and calibrating the first sensor to indicate a closed position each time the barrier is detected to be in the closed position.

A method for detecting a position of a barrier, the method being performed in a status monitor device and comprising the steps of:
- detecting a barrier position of the barrier using a first sensor, the barrier position indicating a degree of opening of the barrier;
- detecting every instance when the barrier is in a closed position using a second sensor;
- and
- re-calibrating the first sensor to indicate a closed position in response to each instance the barrier is detected in the closed position.
A status monitor device for detecting a position of a barrier, the status monitor device comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, cause the status monitor device to:
- detect a barrier position of the barrier using a first sensor, the barrier position indicating a degree of opening of the barrier;
- detect when the barrier is in a closed position using a second sensor;
- and
- in response to each instance of the second sensor detecting the barrier as being in the closed position, automatically re-calibrating the first sensor to indicate the closed position.
A computer program for detecting a position of a barrier, the computer program comprising computer program code which, when run on a status monitor device causes the status monitor device to:
- detect a barrier position of the barrier using a first sensor, the barrier position indicating a degree of opening of the barrier;
- detect when the barrier is in a closed position using a second sensor;
- and
- automatically re-calibrate the first sensor to indicate a closed position for each instance the barrier is detected to be in the closed position by the second sensor.
