Nodes with duplicate ID's #469

Closed seant100 closed 5 years ago

seant100 commented 5 years ago

I occasionally get new nodes appearing that have the same EUI as an existing node. See attached screenshot of example. image

@seant100 If you do not mind, can you send your database backup to my email? jkandasa at gmail dot com

@jkandasa I added the missing unique key constraints in my database and updated to latest snapshot. Will inform if this happens again. Thank you

seant100 commented 5 years ago

@jkandasa It appears logs have many issues trying to read data and then that fails and so it tries to insert a new node. Here is a snippet from the logs where I suspect it is doing this .... Obviously now the fake sensors are not appearing as the new node fails to insert now due to the unique constraint. But this does seem to indicate some underlying issue.

@seant100 I guess this issue related to https://github.com/mycontroller-org/mycontroller/issues/484, fixes this issue too.
