ESP8266-WiFi-Relay-Async

simple sketch for ESP8266 of using ESPAsyncWebServer to switch relays on GPIO pins, serves a simple website with toggle buttons for each relay and uses AsyncWiFiManager to configure WiFi network.

Features

  • Data is encoded as JSON object
  • get and set relay states also by simple GET requests
  • Bootstrap and jQuery for beautiful Web Pages for both Mobile and Desktop Screens
  • ESPAsyncWebServer Library to use syncronous communication
  • ArduinoOTA updates
  • MDNS support

What You Will Need

Hardware

  • An ESP8266 module or development board like WeMos or NodeMcu with at least 32Mbit Flash (equals to 4MBytes)
  • 4 Relay Modules

Software

Building From Source

Please install Arduino IDE if you didn't already, then add ESP8266 Core (Beware! Install Git Version) on top of it. Additional Library download links are listed below:

You also need to upload web files to your ESP with ESP8266FS Uploader.

Unlisted libraries are part of ESP8266 Core for Arduino IDE, so you don't need to download them.

Steps

  • First, flash firmware by Arduino IDE or with your favourite flash tool
  • Flash webfiles data to SPIFFS either using ESP8266FS Uploader tool or with your favourite flash tool
  • (optional) Fire up your serial monitor to get informed
  • Power on your ESP8266
  • Search for Wireless Network "wifi-relay" and connect to it (default password is adminadmin)
  • Normally your system will open a page; otherwise open your browser and type either "http://192.168.4.1" or "http://wifi-relay.local" (.local needs Bonjour installed on your computer) on address bar.
  • Scan for available networks and fill in your password and press save.
  • ESP8266 will reboot and connects to your network.
  • Check your new IP address from serial monitor or DHCP network settings and connect to your ESP8299 again. (You can also use "http://wifi-relay.local").
  • Toggle relay 1, relay 2, relay 3 and relay 4 buttons on or off and enjoy your WiFi relay device.
  • Congratulations, everything went well, if you encounter any issue feel free to ask help on GitHub.
