Hello
I have the Generac Integration setup and it was working fine until a couple of days’ ago. Please see the error message below.
I’m now getting this error message and don’t know how to resolve it:
Thanks in advance for any help that can be provided.
Post the debug error log (formatted) please.
Hello and thanks for the help. I’m not sure if this is what you are looking for and I’m not sure if this is in the correct format, but I pulled it out of the debug report:

A deprecated add-on that stops working in December 2025? I suggest you contact the owner of the Generac add-on for an update, or check in GitHub if the issue has been reported and addressed.
Update. I got it to work by partially deleting the entry within the integration, then following the instructions and creating a new entry. Non of the entities are lost and I didn’t have to recreate the dashboard card.
Glad you found the documentation to solve your issue.
Monitor carefully if the deprecated code persists and it stops working next update in December.
