🏠 Smart Home Control System

Welcome to your personal smart home automation hub! This project lets you control all your smart devices through a simple MCP (Model Context Protocol) server. Whether you want to dim the lights, crank up the AC, or binge-watch your favorite Netflix series, this system has got you covered.

What This Does

Think of this as your smart home's brain. It's an MCP server that connects to various devices around your house and lets you control them through natural language commands. You can control lights, fans, air conditioners, and even your smart TV - all from one place!

The system uses MQTT for real-time communication between devices and stores all your device states persistently, so your settings are remembered even after restarts.

🚀 Quick Setup

Prerequisites

• Python 3.11 or higher
• ADB (Android Debug Bridge) installed for TV control
• Optional: MQTT broker running on localhost

Installation

1. Clone this repository

2. Install dependencies:

   uv sync
   

3. Create a .env file with your authentication credentials:

   AUTH_TOKEN=your_secret_token_here
   MY_NUMBER=your_validation_number
   

4. Run the server:

   python smart_home_server.py
   

The server will start on http://0.0.0.0:8002 and you're ready to go!

• AC temperature: set_device_value("bedroom", "ac1", "temperature", "22")

get_device_state(room, device_name)

Check what's going on with a specific device - is it on? What's the current brightness? Temperature?

get_all_states()

Get a complete overview of every device in your home. Perfect for checking everything at once.

TV Control - Basic Functions

tv_volume_up(room, device_name) & tv_volume_down(room, device_name)

Adjust TV volume. The system tracks the current volume level too.

tv_mute(room, device_name)

Toggle mute on your TV. Hit it again to unmute.

tv_open_app(room, device_name, app)

Launch apps on your TV. Currently supports:

• netflix - Open Netflix
• youtube - Open YouTube
• home - Go to home screen

tv_navigate(room, device_name, direction)

Navigate your TV interface:

• back - Go back one screen
• home - Return to home screen

check_tv_connection(room, device_name)

Test if your TV is connected and responding. Great for troubleshooting!

TV Setup & Management

add_tv_device(room, device_name, ip_address, port=5555)

Add a new smart TV to your system. You'll need the TV's IP address (find it in your TV's network settings).

Example: add_tv_device("livingroom", "main_tv", "192.168.1.100")

update_tv_config(room, device_name, ip_address, port=5555)

Update an existing TV's network settings. Useful when your TV gets a new IP address.

remove_tv_device(room, device_name)

Remove a TV from your system completely.

list_tv_devices()

See all your configured TVs, their IP addresses, and connection status.

load_tv_configs_from_file()

Load TV configurations from a JSON file. You can manually edit device_states/tv_config.json to add multiple TVs at once.

Advanced TV Content Control

tv_search_and_play(room, device_name, query, app="netflix")

The crown jewel! Search for content and automatically start playing it.

Examples:

• tv_search_and_play("livingroom", "tv", "Breaking Bad", "netflix")
• tv_search_and_play("bedroom", "tv", "funny cat videos", "youtube")

tv_search_content(room, device_name, query, app="netflix")

Search for content but don't auto-play. Let you browse the results first.

play_netflix_show(room, device_name, show_name)

Dedicated Netflix function with enhanced error handling and troubleshooting tips.

play_youtube_video(room, device_name, search_query)

YouTube-specific search with smart fallbacks when the interface is tricky.

youtube_voice_search_workaround(room, device_name, search_query)

Alternative YouTube search using voice search interface. Sometimes works better than regular search.

TV Remote Control

tv_send_text(room, device_name, text)

Type text into TV search fields or any text input.

tv_press_key(room, device_name, key)

Press specific remote control buttons:

• Navigation: up, down, left, right, enter, back, home
• Media: play, pause, search, menu

youtube_navigate_and_play(room, device_name, direction="down", steps=1)

Navigate YouTube's interface manually. Useful when automatic search fails.

Troubleshooting

diagnose_tv_connection(room, device_name)

Run comprehensive diagnostics on your TV connection:

• Network connectivity test
• ADB connection status
• Device responsiveness check
• App availability verification

Perfect for figuring out why your TV isn't responding!

🏠 Room Management

The system is smart about room names. You can use natural variations:

• "living room", "livingroom", "lounge", "hall" → all become "livingroom"
• "bed room", "bedroom", "master bedroom" → all become "bedroom"
• "kitchen", "cook room" → both become "kitchen"

🤔 Troubleshooting TV Setup

If your android TV isn't connecting:

1. Enable Developer Options: Go to Settings → About → Keep pressing on "Build" until developer mode activates
2. Enable USB Debugging: In Developer Options, turn on "USB Debugging"
3. Enable Network ADB: Turn on "Network ADB" if available
4. Check IP Address: Make sure you have the correct IP (Settings → Network) and IP changes everytime you start the TV
5. Same Network: Ensure your TV and server are on the same WiFi network
6. Use Diagnostics: Run diagnose_tv_connection() for detailed troubleshooting

🎉 Getting Started

1. Start with basic devices like lights and fans
2. Add your TV using add_tv_device()
3. Test the connection with check_tv_connection()
4. Try some basic TV controls like volume or opening apps
5. Experiment with content search and playback
6. Use diagnose_tv_connection() if you run into issues

That's it! You now have a full smart home control system that can handle everything from dimming lights to finding your next binge-watch series. Enjoy your automated home! 🏡✨
