Basic Usage

#include <Firmngin.h>

// Initialize device
Firmngin device("DEVICE_KEY", "API_KEY");

void setup() {
    device
        .setWiFi("SSID", "PASSWORD")
        .enableAutoReconnect()
        .setMqttServer("broker.hivemq.com", 1883)
        .addOutputPin(LED_BUILTIN)
        .asDigital()
        .begin();
}

void loop() {
    device.run();
    
    // Update pin value
    device.updateValue(LED_BUILTIN, HIGH);
    
    // Update custom data
    device.updateCustomData("temperature", 27.5);
    
    // Batch update
    device
        .beginUpdateBatch()
        .updateValue(LED_BUILTIN, HIGH)
        .updateCustomData("humidity", 80)
        .endUpdateBatch();
}
