Invalid config for ‘group’ at packages/lexmark_office_mc3224i.yaml, line 17: ‘mc3224i’ is an invalid option for ‘group’, check: group->Lexmark->mc3224i, please check the docs at Group - Home Assistant

are u sure the error corresponds with the config u pasted?

line 17: ‘mc3224i’ is an invalid option for ‘group’ – i don’t see the mc3224i option in the config u pasted.

I had renamed some things few times. Trying to get things as closely aligned to the same printer that IPP was able to discover. IPP didn’t provide me as much information as I wanted so I created a package. Long and short was after deleting the package and restarting HA everything is fine now.
