ESP8266 Smart Home WiFi Button

The IoT Click:

The IoT Click is a multifunctional WiFi button for home automation. Easily automate your smart lighting, sockets (e.g. WLED, Shelly, devices from home assistant, etc.) with just the push of a button.

Required Parts:

Wiring schematic:

You have to bend the Pins of the AAA-Contacts and the button
Put the ESP01s to the side
Insert the AAA-Contacts after soldering

Programming the ESP01s:

Use Arduino IDE, select Generic ESP8266 Module and flash to the ESP01s.

Code:

#include <ESP8266WiFi.h>

//CHANGE VARIABLES
const char* ssid = "Your SSID here";
const char* password = "Your PASSWORD here";

int startTime;

void setup() {
  //connect to WiFi
  WiFi.begin(ssid, password);
  WiFi.reconnect();

  //wait for connection to establish
  startTime = millis();
  while ((WiFi.status() != WL_CONNECTED) && (millis() - startTime <= 5000)) {
    delay(5);
  }

  if(WiFi.status() == WL_CONNECTED) {
    //ADD YOUR CODE HERE
    //do something
    
  } else {
    //error no WiFi Connection
  }
  ESP.deepSleep(0);
}

void loop() {
  //empty
}

Have fun building the project!
Stay ceative!
