Logs of triggers and events?

I know there is an event log. It shows that a timestamp, what and reporting status.
Is there a way to see what triggered it?
I have a lock that randomly unlocks. It began to happen after the 12/10 update. It just unlocks after I leave for work.

Not the same time. Just wanted to see if it could report and log if a sensor/switch/automation causes it. Basically a more detailed log that points out why it’s “unlocked”.
Thanks.

Just instead of using the link to graph.API.smartthings just go to

https://account.smartthings.com/

That will then take you to the correct “Shard” for your account.

(The original FAQ was written back when everybody was on the same shard.)
