Abstract: The disclosure relates to a system (100) for collision and intrusion detection of a door (1), the system (100) comprises a movement sensor (10a, 10b) configured to be arranged at the door (1) to detect movement of the door (1), a processing circuitry (102a, 102b, 102c) configured to cause the system (100) to obtain, by the movement sensor (10a, 10b), movement data indicative of a movement of the door (1), analyze the movement of the door (1) during a predefined time period based on the obtained movement data, and utilize a movement-to-event model to determine a probable event that caused the movement of the door (1). The disclosure further relates to a method for collision and intrusion detection of a door (1) and a computer program product (500).

Abstract: It is provided a method for determining when to perform maintenance of a door (15). The method is performed by a maintenance determiner (1). The method comprises: obtaining (40), from a first sensor (6), sensor data indicating kinetic performance of the door: defining (42) a start time of the sensor data based on a first event detected by a second sensor (7), to enable synchronisation of the sensor data: dividing (46) the sensor data in a plurality of time periods (24a-c): evaluating (48) the sensor data in each one of the plurality of time periods by comparing to reference data respectively associated with each one of the plurality of time periods; and determining (50) to perform maintenance, based on the evaluation of the sensor data.

Abstract: It is provided a method for routing data in a communication network (8). The method being performed by a routing node (3). The method comprises: receiving (40) an uplink message from an end node (2) over a multicast wireless transmission; forwarding (42) the uplink message towards a destination node over a unicast transmission; receiving (44) a downlink message over a unicast transmission; determining (46) that a recipient of the downlink message is the end node (2); and transmitting (48) the downlink message over multicast to the end node (2). Corresponding routing node, gateway, computer programs and computer program products are also provided.

Abstract: It is provided a method for enabling detecting suspicious activity by an electronic lock (2). The method comprises: obtaining (40) communication data being metadata of communication to and/or from the electronic lock (2); obtaining (42) internal state data being metadata of an internal state of the electronic lock; obtaining (44) event data indicating at least one event and a time of for the event, wherein the event has occurred for the electronic lock; and transmitting (46) the communication data, the internal state data and the event data to a monitoring server (3). Corresponding electronic lock (2), monitoring server (3), computer programs (67, 167, 91) and computer program products (64, 164, 90) are also provided.
