lgtvremote-cli 1.3.1

Command-line interface for controlling LG webOS TVs

LG TV Remote CLI

Command-line interface for controlling LG webOS TVs over your local network.

Communicates via WebSocket using the SSAP (Simple Service Access Protocol) on port 3001. Supports TV discovery, PIN-based pairing, remote control, app launching, input switching, Wake-on-LAN, and more.

Installation

Only Python 3.9+ is required (ships with macOS and most Linux distros).

# Install from PyPI (recommended)
pip install lgtvremote-cli

# Or with pipx (isolated environment, great for CLI tools)
pipx install lgtvremote-cli

Install from source

git clone https://github.com/griches/lgtvremote-cli.git
cd lgtvremote-cli
pip install .

If you don't have Python 3 installed:

Platform	Install
macOS	brew install python3
Ubuntu/Debian	sudo apt install python3
Fedora/RHEL	sudo dnf install python3
Windows	winget install Python.Python.3 or python.org

Quick Start

# 1. Scan, add, and pair — all in one step
lgtv scan
# Finds TVs, adds them, asks to pair, fetches MAC addresses for Wake-on-LAN

# 2. Control your TV
lgtv off                    # Turn off
lgtv on                     # Wake via Wake-on-LAN
lgtv launch Netflix         # Launch apps by name
lgtv volume set 20          # Set volume
lgtv input 1                # Switch to HDMI 1

Or if you know the IP:

lgtv add 192.168.1.100      # Adds, pairs, and fetches MACs automatically

Configuration

Device data is stored in ~/.config/lgtvremote/devices.json. This includes IP addresses, names, MAC addresses, and pairing keys.

Using with AI Assistants

This CLI is designed to be easily used by AI assistants and automation tools. Run lgtv -h for the full command list, or lgtv <command> -h for detailed help on any command.

Key patterns:

• All commands return human-readable output to stdout
• Errors go to stderr with non-zero exit codes
• lgtv apps and lgtv inputs list available options with IDs
• lgtv raw allows sending any SSAP command for capabilities not covered by named commands

Network Requirements

• Your computer and TV must be on the same local network
• Port 3001 (WSS) must be accessible for TV control
• Port 3000 (HTTP) is used for device discovery enrichment
• Port 1900 (UDP) is used for SSDP discovery
• Ports 7 and 9 (UDP broadcast) are used for Wake-on-LAN
