Sure, but wall timers (for lamps) have a garbage user experience, and for the price of one wired-in fixture timer (where a wall switch would go) + new bulbs you might as well have bought a smart hub.
The problem is badly designed interfaces, not the underlying technology itself.
as far as I can make out, most "smart" devices have garbage UX and reliability, not to mention they'll sell you out to any intelligence agency you'd care to mention.
and what's more, the stuff that worked 50 years ago will probably still work in another 50 months whereas I'd be surprised if the modern junk would last 15 months.
