Can no longer find time_elapsed entity

[jezzaaa]

Hi. I installed your awesome plug-in to my HA deployment, using HACS. I used the "time_elapsed" entity value in an automation to notify my when a long print (>15m) had finished.

Recently this stopped working. On investigation, the automation is complaining that time_elapsed is not a thing.

I don't recall changing anything that would have caused this. But I don't know how to restore this entity, and I really don't know where to start looking for it.

Can anyone help me?

Nevermind. I took a second look at some of the other issues, and this seems to be a duplicate.
