Exactly!

If your device requires, in any way, an internet or cloud connection, even just for setup, it doesn't exist for me. If you have some FULLY OPTIONAL services I might like as a SAAS free or subscription option, ok; but the device MUST 100% work without ever knowing your cloud exists. It must also be designed to fail-safe and have manual fall-back operability (e.g., when the power goes out, I can still manually switch its state to OFF).

I recall an article or comment on HN talking about the advantages of a "MidWit Home", devices that weren't really smart, and just had remote control. I've got a bit of that with some remote switches to use around the house with enough range we can turn on from the car when arriving home. Also timers. Seems like a good way to go.
