ESP32 Switches

This project is designed to work with the Switch Controller App.
It allows an ESP32 microcontroller to send button press events to the Switch Controller, which then triggers actions such as turning on a light via Home Assistant.

Sending Requests from ESP32 to the Switch Controller App

The ESP32 can send HTTP POST requests to the Switch Controller App to trigger different switch actions.

# Trigger switch 1 (short press)
POST http://localhost:8080/esp
Content-Type: application/json

{
  "uuid": "bd4a6037-0864-4b0e-80e1-8d1c87bf9aa0",
  "friendly_name": "Küche hinten",
  "ip": "192.168.101.181",
  "action": "switch_1_short"
}

# Trigger switch 1 (long press)
POST http://localhost:8080/esp
Content-Type: application/json

{
  "uuid": "bd4a6037-0864-4b0e-80e1-8d1c87bf9aa0",
  "friendly_name": "Küche hinten",
  "ip": "192.168.101.181",
  "action": "switch_1_long"
}

# Trigger switch 2 (short press)
POST http://localhost:8080/esp
Content-Type: application/json

{
  "uuid": "bd4a6037-0864-4b0e-80e1-8d1c87bf9aa0",
  "friendly_name": "Küche hinten",
  "ip": "192.168.101.181",
  "action": "switch_2_short"
}

# Trigger switch 2 (long press)
POST http://localhost:8080/esp
Content-Type: application/json

{
  "uuid": "bd4a6037-0864-4b0e-80e1-8d1c87bf9aa0",
  "friendly_name": "Küche hinten",
  "ip": "192.168.101.181",
  "action": "switch_2_long"
}

How It Works

1. Button Press on ESP32 → The ESP32 detects the button press event.
2. Sends an HTTP Request → The ESP32 sends a request to the Switch Controller App.
3. Action Execution → The Switch Controller App triggers the appropriate action (e.g., turning on a light in Home Assistant).

This setup allows for easy integration with smart home automation, making it a great way to trigger Home Assistant scenes, automations, or direct device control using physical buttons.
