EasyIoT @ instructables.com shows us how to build an Internet connected switch using ESP8266 Wifi module and EasyIoT Cloud service.
In this tutorial we will show how to build WiFi internet connected switch connected to EasyIoT Cloud. We will use ESP8266, solid state relay and Arduino IDE. Switch can be controlled by WEB application, native Android application or button.
This internet switch is “plug and play” – it will automatically set all EasyIoT Cloud settings, so no configuration in EasyIoT Cloud is needed.
