Smart switch compatibility without neutral wire

[SlabSlayer]

A no-neutral Wyze Switch was previously requested in the Wishlist topic linked below. The request was in the researching phase for some time and Wyze was in the process of testing the feasibility of hardware possibilities internally. Unfortunately, because Wyze has shifted their focus to only cams, and what appears to be AI improvements in the coming year, the No-Neutral Switch project was killed. Wyze posted about it in a recent AMA event:

Q: There was talk a while ago of smart switches that didn’t need a neutral. Is this still on the table or was it abandoned?
A: We’re sorry, there is a technical challenge that we haven’t been able to overcome. We don’t believe that the tradeoff would offer an acceptable experience to customers so we cancelled the project. -u/WyzeDS

WiFi-enabled wall switch that does not require a neutral

Please develop a wireless light switch that does not require a neutral. I would rather have smart switches than smart bulbs. [Mod Edit]: Title modified to be more inclusive and to enhance search clarity.
