pymotivaxmc2 0.7.0

Async Python library for Emotiva XMC-2 and related devices

pymotivaxmc2

A slim asynchronous Python library for controlling Emotiva XMC‑2 (and compatible) devices over their UDP remote interface.

Features

• Asynchronous API for non-blocking operation
• Type-safe command and property access via enums
• Automatic protocol version negotiation
• Property change notifications
• Command-line interface for quick testing

Installation

pip install pymotivaxmc2

Quick Start

import asyncio
from pymotivaxmc2 import EmotivaController, Property, Command, Zone

async def main():
    # Create controller for device at 192.168.1.50
    ctrl = EmotivaController("192.168.1.50")
    
    # Connect to the device
    await ctrl.connect()
    
    # Subscribe to volume changes
    await ctrl.subscribe(Property.VOLUME)
    
    # Register callback for volume changes
    @ctrl.on(Property.VOLUME)
    async def vol_changed(value):
        print(f"Volume is now {value} dB")
    
    # Set volume to -25 dB
    await ctrl.set_volume(-25.0)
    
    # Power on the device
    await ctrl.power_on()
    
    # Wait a minute
    await asyncio.sleep(60)
    
    # Disconnect
    await ctrl.disconnect()

if __name__ == "__main__":
    asyncio.run(main())

Command-Line Interface

The package includes a command-line interface for quick testing:

# Power control
emu-cli --host 192.168.1.50 power on
emu-cli --host 192.168.1.50 power toggle

# Volume control
emu-cli --host 192.168.1.50 volume up --step 2
emu-cli --host 192.168.1.50 volume set -28.5

# Zone 2 control
emu-cli --host 192.168.1.50 zone2 power on
emu-cli --host 192.168.1.50 zone2 volume down

# Input selection
emu-cli --host 192.168.1.50 input set hdmi3

# Status query
emu-cli --host 192.168.1.50 status power volume mute input
