I had several light groups in my configuration.yaml file that I just duplicated using the new groups helper. Everything went fine. I created the new helper, gave it the same name, added the individual lights, and removed the corresponding lines from my configuration.yaml file.
The entity ID of the new group added an ā_2ā since it was a one-to-one copy of the original, but I figured that was no big deal; I would just remove that after I rebooted and the one from configuration.yaml was gone.
Wrong.
I renamed the new helper group entity no problem, but there is an orphaned entity with the trailing ā_2ā name showing up in my entities list. It is not in my automations.yaml, scripts.yaml, or configuration.yaml files. The light group is named correctly and responds to commands.
I cannot clean up the remnants of migrating from the configuration.yaml light group to the new helper light group.
Any ideas?
