15+ year sysadmin, I don't have smart home anything cause I don't want more shit to manage when I'm not working.
I barely touch my home network and servers cause I wait til something is obsolete or broken, then I replace with something that will have a long life and set it up to manage itself wherever possible. Some friends have really cool self hosted smart home setups and they like working on it as a hobby, not for me but I enjoy seeing them soldering boards for it and all that.
