Wi Fi Sockets Controlled by Phone.

[EasilyTheBest]

Hi, I have been looking on ebay and Amazon for a wi fi controlled socket, it so I can turn an appliance on or off over the internet.
There are tons available but they all Mention theres only an app for Android and IOS. I can't find any that mention Windows Phone plus none seem to mention if you can still control the socket just through the internet without any app, like from a Windows Laptop.
Really hoping someone could suggest something.
By the way, I'm in the U.K.
Thanks
