Electromechanical lock and method

An electromechanical lock comprising:

• a magnetically-operated actuator to switch between a first mechanical state and a second mechanical state using either a first internal magnetization configuration or a second internal magnetization configuration;
• a magnetic sensor to measure a prevailing magnetic field caused by the magnetically-operated actuator;
• and
• a processor to command the magnetically-operated actuator to switch between the first mechanical state and the second mechanical state using either the first internal magnetization configuration or the second internal magnetization configuration, and after the switching, to command the magnetic sensor to measure the prevailing magnetic field, to test the prevailing magnetic field against a set of the predefined magnetic fields, and based on the testing, to detect whether the switching between the first mechanical state and the second mechanical state was completed or not completed,
• wherein the set of the predefined magnetic fields comprises four predefined magnetic fields, wherein two desired predefined magnetic fields correspond to proper functions of the magnetically-operated actuator, and two undesired predefined magnetic fields correspond to malfunctions of the magnetically-operated actuator.
