[Disclaimer: I'm only an amateur electronics hobbyist. The idea below may get me LOL'd at by the experts and get you electrocuted!] If I were doing this, I would build the power outlet myself using an ESP8266 programmable wifi module and a 110V AC to 3.3V DC switching power supply module. ESP8266 can connect to your wifi network, and run a TCP socket server, or a web server to receive HTTP commands. Your phone/tablet sends commands to it over your wifi network using TCP or HTTP. Connection would be like : 110V AC -> switching supply -> 3.3V DC -> powers ESP8266 always on -> switches a relay to supply or cut power at the output side Cost: An ESP8266 is around $3 and switching module is around $6 on aliexpress.
