Philips Hue have the ability to work without internet and it seems like a lot of people like them, though they are kind of expensive. I’ve used Sengled bulbs before and they were fine, not sure how well they work without internet. But I think for you the problem isn’t the bulbs reliance on the internet, they just seem very forgetful. For both Hue and Sengled, when the power comes back on after being out, they just start working again on their own after about a minute. No need to reset anything.

The main non-techy issue even for locally controllable smart things is that the big voice assistants are all entirely internet dependent. So even though Hue bulbs are technically controllable locally if your internet is out, Alexa and Google Home both won’t be able to do anything with them.

How can you improve perfection?

I think it takes that into account. It’s going off the actual music files, not the artist/album metadata as far as I’m aware. But yeah that’s fair, you can download playlists for offline but it isn’t as seamless as just having the files locally

Ive never used SensMe, but from the description PlexAmp Sonic Sage might be similar to what you’re looking for?
