Methods of replacing sensor devices

A method performed by a second sensor device, the method comprising steps of:

• i. receiving a broadcasted signal from a first sensor device and establishing a direct connection between the first sensor device and the second sensor device;
• ii. receiving first identity information and connection information from the first sensor device via the direct connection, wherein the first identity information identifies the first sensor device to a processing node, and the connection information is used by the first sensor device to connect to the processing node;
• iii. connecting to the processing node using the connection information and requesting the registration of the second sensor device with the processing node as a replacement for the first sensor device using the first identity information and second identity information, wherein the second identity information identifies the second sensor device;
• and
• iv. transferring, to the first sensor device, a confirmation that the second sensor device has been registered with the processing node as a replacement for the first sensor device.

A method performed by a processing node, the method comprising steps of:

• i. receiving, from a second sensor device, a request to register the second sensor device as a replacement for a first sensor device, the request comprising first identity information identifying the first sensor device and second identity information identifying the second sensor device;
• ii. based on at least one of the first identity information identifying the first sensor device and the second identity information identifying the second sensor device, determining that the first sensor device is allowed to be replaced by the second sensor device;
• iii. registering the second sensor device as a replacement for a first sensor device;
• and
• iv. transferring, to the second sensor device, a confirmation that the second sensor device has been registered with the processing node as a replacement for the first sensor device.
