// Server starts automatically in MainActivity
webSocketManager.startServer { json -> 
    handleCommand(json) 
}

Sending Commands

# Go app (web interface)
# Open browser at http://localhost:3000 (or next available port)

# Python example
import websocket
ws = websocket.WebSocket()
ws.connect("ws://TV_IP:8080")
ws.send('{"action": "play"}')
