I asked something similar a few weeks ago for the “Adguard Home” add-on. But today my question is more general. I realized (or I think to realize) that there is no way to change to credentials of any add-on, which is configured about the UI.
If an add-on is integrated over yaml, the secrets.yaml could be used and there are changes possible. But if I add something like “Adguard Home” or “AVM FRITZ!Box”, I will be asked for the credentials, but then there is no edit button to change them. Could this be right? Deleting and adding again will delete all historical data!?
