I had a clear out of users on my system that I somehow managed to create when fiddling with HA in the early days. I now have only one user (for now).
How do I update the overview screen to remove this person that no longer exists, and add in the one that does ? If I try to edit this screen, I can add more tiles, but cannot edit this!
You can just edit the Lovelace page.
3 dots at the top right > Configure UI. Edit the tab you are on with the little pencil icon and goes to the badges tab.
You can then add/remove the badges from there.
Ah, great - found it! I was trying to just click on it and expected a way to config, as with the other tiles. However, its hidden a little in a sub edit menu as a ‘badge’.
