A short review of Slampher and Sonoff - ESP8266 + radio-based controllers - http://tech.scargill.net/itead-slampher-and-sonoff/
Great idea! I would have bought some of these if they wouldn’t make use of a cloud service for control. I’m not really keen on knowing everyone out there when I switch on and off my lights. And I do like to be able to turn on my lights even if there is no Internet connection
