Since we first started experimenting with ESP Wi-Fi Modules, we have wanted to create a smart Wi-Fi socket that would allow us to use a smartphone to wirelessly control our AC loads. While products like these are already on the market, such as the popular Moko WiFi Smart Plug or Sonoff, they are a bit pricey and don't give you the joy of building your own. So, in this project, we'll show you how to make your own Smart plug out of an ESP8266 Wi-Fi module. The device that we created can be easily plugged into any existing AC socket, and then you can connect the actual load by simply plugging it into this socket to our devices. You just contact us, and we assist you so that you can control the electrict from the plug directly from your smartphone.
