If it's just dimming you could go with dumb dimmable bulbs and just make the light switch "smart".
Apparently modern dimmers just PWM the power so it wouldn't take much to make something that does that. I assume LED bulbs work nicely with dimmers by now.
The smart light switch has exactly the same problems as the smart bulb, and it's much harder to replace.
But the benefit of a smart switch is that it remains "always on" for remote control, and physical actions on the switch also reflects on its state at the software level.
That said, I'd go with stuff that don't need online connectivity.
Smart switches aren't really a big deal to swap in. Plus, there's more options for purely local only devices based on espHome.
The only reason I didn't go that route is because I have wall sconces that I wanted to separate from pot lights, and I really don't like doing drywall repairs.
I'm having a problem with smart switches maybe someone knows the solution, my switches don't have positive and negative, they are 1 wire only, there are some solutions that use a super capacitor I installed one as a test and it works fine.
That said, I'm looking for dimmable and/or ZigBee alternatives that work that way.
In my case, I don't want all the bulbs on, and splitting up the circuit now would involve cutting holes in my ceiling and walls. Otherwise, yeah, I would have gone with a smart switch. Most LED bulbs are dimmable these days.
it very much helps to be able to set colour temperature as well as hsl
