Connect physical devices to Lua AI agents via MQTT.

lua-device-client

Connect physical devices to Lua AI agents via MQTT.

Install

pip install lua-device-client

Quick Start

import asyncio
from lua_device import DeviceClient, DeviceCommandDefinition

client = DeviceClient(
    agent_id="baseAgent_agent_abc123",
    api_key="api_your_key_here",
    device_name="warehouse-scanner",
    commands=[
        DeviceCommandDefinition(
            name="scan_barcode",
            description="Scan a barcode and return its value",
        ),
        DeviceCommandDefinition(
            name="get_status",
            description="Return device battery and connectivity status",
        ),
    ],
)

async def handle_scan(payload):
    return {"barcode": "ABC-12345", "format": "CODE128"}

async def handle_status(payload):
    return {"battery": 85, "signal": "strong"}

client.on_command("scan_barcode", handle_scan)
client.on_command("get_status", handle_status)

async def main():
    await client.connect()
    print("Device connected!")

    # Fire a trigger to the agent
    ack = await client.trigger("barcode_scanned", {"value": "ABC-12345"})
    print(f"Trigger acknowledged: {ack}")

    # Keep running
    await asyncio.Event().wait()

asyncio.run(main())

Features

• MQTT transport -- connects to Lua AI via MQTT (paho-mqtt)
• Self-describing commands -- no server config needed
• CDN uploads -- upload screenshots and files via CDN.upload()
• Device triggers -- fire events from device to agent
• Auto-reconnection -- exponential backoff
• Async/await -- built on asyncio

MicroPython

For Raspberry Pi Pico W and other MicroPython boards, use the standalone MicroPython client included in lua_device/micropython.py. See the MicroPython docs for details.
