This is another cheap plug in Wi-Fi mains socket that uses the ESP8266, comparable to the Sonoff S20. Cost was £8.34 + £2.34 shipping to the UK from TVC-Mall. It is also available from Banggood for a little more and is starting to show up on eBay now too.
I didn’t try the standard software/firmware combination, it’s likely to be as rubbish as they usually are and I need MQTT support so I jumped straight into flashing something more useful. This one isn’t supported as standard by my favoured firmware TASMOTA but it is easy to add it in.
Rated current is 10A, maximum power 2000W. It has an FCCID (2AJK8-SWA1) and is CE marked.
