Delete Thingsboard Edge device does not delete it on Thingsboard CE

hello @joinke

this is "by design". In the PE version, the device could be assigned to multiple edges, and removal of the device from one edge, should not affect removal from another - that's why in the case of removal from the edge, the device on the cloud is not removed, but unassigned from the edge. CE and PE versions must have similar approaches to handling events - because of this, CE version doesn't remove the device as well - only unassign it from the edge.

If you would like to remove the device from the cloud in case of removal on the edge, you have two possible options.

If you are building from sources, you can update DeviceEdgeProcessor https://github.com/thingsboard/thingsboard/blob/master/application/src/main/java/org/thingsboard/server/service/edge/rpc/processor/DeviceEdgeProcessor.java and replace code: to delete the device and not unassign it from the edge.

So it's going to look like this:

If you are using official images and would like to avoid changing source code - you can add a rule chain to the edge, that is going to remove the device from the cloud by the REST API call

So you can add 'Remove Device From Cloud' rule chain, assign it to edge, and modify root rule chain, to push 'Entity Deleted' events into this rule chain. Edge is going to remove device by REST API from the cloud.
