Please develop a wireless light switch that does not require a neutral. I would rather have smart switches than smart bulbs.
There’s an item on the wishlist for a wired smart switch but you would like a wireless one?
I don’t know if that is physically possible, unless the “smart” circuitry were battery powered.
Edit: Looks as if some of these exist but they drain a little power vampirically and use Z-Wave or another low power tech to reach a powered hub. They also don’t work well with LED bulbs?

No matter how the operational method (wired or wireless), the device must include a neutral conductor because the light you want to control also requires a neutral. The electric circuitry for a wall mounted light switch is essentially the same as a smart plug, so it should be easy to design and manufacture.
