WARNING!! You will play with LIVE MAINS!! Deadly zone!! Relays can be controlled from anywhere in the world - you just need internet connection.ĭevices can be controlled over EasyIoT Cloud interface or native Android Application. You can easy extend program to control more relays with single ESP8266. Program code is simplified - it's not plug and play, with hard coded configuration, but it uses 4 relays instead of just one. ![]() ![]() ![]() ![]() This internet connected switch is simplified version of ESP8266 internet connected switch. We will use Arduino IDE to program ESP8266 In this tutorial we will show how to build WiFi internet controlled switch connected to EasyIoT Cloud with 4 relays and one ESP8266.
