HomeAssistantManager - A wrappe for MQTT autodiscovery

HomeAssistantManager is a lightweight MQTT auto-discovery library only for ESP32 that eliminates boilerplate code for Home Assistant integration.

Key features:

• Auto-discovery via MQTT - devices appear in HA automatically
• Simple API for sensors, switches, buttons, and binary sensors
• Built-in diagnostics (RSSI, uptime, heap, reset reason)
• Production-ready with comprehensive examples

Show me the code!

Here's a complete example that creates a temperature sensor and a button:

#include "HomeAssistantManager.h"

HA::Manager Manager("your-ssid", "your-password", "mqtt-host");
HA::Sensor::Generic tempSensor(&Manager, "Temperature", HA::Temperature);
HA::Button::Generic testButton(&Manager, "Test Button");

void setup() {
    Manager.begin("ESP32_HASS", "MyCompany", "ESP32", "1.0.0");
    testButton.setCommandCallback([]() { 
        Serial.println("Button pressed from HA!"); 
    });
}

void loop() {
    hassManager.loop();
    tempSensor.setValue(23.5, 1);
    delay(5000);
}

That's it! Your device appears in Home Assistant automatically (requires MQTT integration configured).

Supported: Sensors, Binary Sensors, Buttons, Switches, plus auto-diagnostic sensors.
