Has anybody got Aisirer Alexa plugs to work with HA?

Amazon is selling Alexa controlled 13A socket adapters for a very reasonable price at the moment. They obviously use Wi-Fi to reach the Internet.

Personally, I won’t have Alexa or any of its siblings in my house, but I’d like to able to use sockets that are cheaper than the Z-Wave ones I use now. Has anybody got these (or similar cheap UK sockets) to work with HA?
