There is a line of lutron switches that are dead simple, no smarts, no hub … and a cute little remote that everyone in my family uses to “all off” the interior lights.
We have a no smart devices policy in the house and these make the cut …
EDIT: From my notes ... the specific product line is "maestro wireless" and I have MRF2-6CL switches paired with "pico" remotes. This is as opposed to the caseta line from Lutron which is quite a bit "smarter".
I still use HA on a RPi4 for other things, typically via Zigbee, but the Casetas always work like you'd expect from a light switch while also enabling smart stuff like voice control or automations.
