// Example: Reading NFC Tags
class NFCActivity : AppCompatActivity() {
    private lateinit var nfcAdapter: NfcAdapter
    
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        nfcAdapter = NfcAdapter.getDefaultAdapter(this)
    }
    
    override fun onNewIntent(intent: Intent) {
        super.onNewIntent(intent)
        if (NfcAdapter.ACTION_TAG_DISCOVERED == intent.action) {
            val tag = intent.getParcelableExtra<Tag>(NfcAdapter.EXTRA_TAG)
            // Process NFC tag data
        }
    }
}

// Real-time power monitoring
class PowerMonitorService {
    fun connectToSmartMeter() {
        // Connect to Eagle-200 API
        val client = OkHttpClient()
        val request = Request.Builder()
            .url("http://$EAGLE_IP/cgi-bin/post_manager")
            .post(xmlBody)
            .build()
            
        // Process real-time data
        client.newCall(request).enqueue(object : Callback {
            override fun onResponse(call: Call, response: Response) {
                val power = parseXmlResponse(response.body?.string())
                updateUI(power)
                sendToCloud(power)
