OK, those don’t exist in Z wave yet, the radios are too bulky. Some of the manufacturers have talked about designing one once the smaller 700 series chip are available, but that could mean another two years before they come to market. I know at one point Inovelli was considering it, but I don’t think they went ahead with the design.
As far as the available Wi-Fi ones, speaking just for myself, I don’t wire anything into the Mains which isn’t UL or ETL certified.
That said, TPLink has an official integration and is very popular. It’s Wi-Fi, and I don’t know the exact specs, but there are a lot of people using it. No USB charger port, though.
If you find one you like better that doesn’t already have a smartthings integration, but that works with Alexa, you can use that as a “man in the middle“ for smartthings integration.
But if you want zwave, you’re just going to have to wait a while.
