pyopus-smarthome 0.1.1

Async Python client for OPUS SmartHome gateway REST API

pyopus-smarthome

Async Python client library for the OPUS SmartHome gateway (also marketed as OPUS greenNet). It provides HTTP API access and a real-time NDJSON event stream over a local network connection.

---

Credentials

The gateway uses HTTP Basic Auth on port 8080. The password is derived from the gateway's EURID — the last 8 hex characters, uppercased.

You can find the EURID on the QR code label on the gateway, or decode it with the included opus-qr CLI tool. The library handles password derivation automatically — just pass the EURID.

---

Installation

pip install pyopus-smarthome

Or with uv:

uv add pyopus-smarthome

---

Quick start

import asyncio
from pyopus_smarthome import OpusClient

async def main():
    # Connect using gateway IP and EURID (from GET /system/info)
    client = OpusClient("192.168.1.100", eurid="YOUR_EURID")

    gateway = await client.get_system_info()
    print(f"Gateway: {gateway.version}")

    devices = await client.get_devices()
    for d in devices:
        print(f"  {d.friendly_id}: cover={d.is_cover} climate={d.is_climate}")

    # Control a roller shutter
    await client.set_state("DEVICE_ID", "position", 50)

    await client.close()

asyncio.run(main())

---

Real-time event stream

OpusStream connects to the gateway's NDJSON server-sent event endpoint and dispatches callbacks when device states change or telegrams arrive.

import asyncio
from pyopus_smarthome import OpusStream, Device, Telegram

def on_devices(devices: list[Device]) -> None:
    for d in devices:
        print(f"Device update: {d.friendly_id}")

def on_telegram(telegram: Telegram) -> None:
    for fn in telegram.functions:
        print(f"Telegram: {fn.key} = {fn.value}")

async def main():
    stream = OpusStream(
        "192.168.1.100",
        eurid="YOUR_EURID",
        on_devices=on_devices,
        on_telegram=on_telegram,
        reconnect_delay=30.0,
    )
    await stream.start()

    # Run until interrupted
    try:
        await asyncio.sleep(3600)
    finally:
        await stream.stop()

asyncio.run(main())

Supported device types

The library models the following device categories (detected from deviceType and function keys):

Category	is_* property	Description
Roller shutters	device.is_cover	Position control (0–100%)
Heating zones	device.is_climate	Set-point and current temperature
Temperature/humidity sensors	device.is_sensor	Read-only sensor values
Doorbell	device.is_doorbell	Binary press events

API reference

OpusClient

OpusClient(host: str, eurid: str, port: int = 8080, session: aiohttp.ClientSession | None = None)

Method	Description
await client.get_system_info()	Returns a Gateway with version and EURID
await client.get_devices()	Returns list[Device]
await client.set_state(device_id, key, value)	Send a state update to a device
await client.update_device(device_id, friendly_id, room_name)	Rename a device or room
await client.get_device_configuration(device_id)	Raw configuration dict
await client.close()	Close the underlying HTTP session

OpusStream

OpusStream(host, eurid, port=8080, on_devices=None, on_telegram=None, reconnect_delay=30.0)

Method	Description
await stream.start()	Open the stream and begin dispatching callbacks
await stream.stop()	Stop the stream and close the connection

Models

• Gateway — gateway system info (version, eurid, serial)
• Device — device with device_id, friendly_id, location, states: list[DeviceState]
• DeviceState — a key/value/unit triplet
• Telegram — incoming radio telegram with device_id and functions: list[TelegramFunction]
• TelegramFunction — key + value pair from a telegram

Auth helpers

from pyopus_smarthome import derive_admin_password, derive_config_password, parse_qr_code

password = derive_admin_password("00AABBCCDD")   # -> "AABBCCDD"

# Or derive credentials from the gateway QR code label
creds = parse_qr_code("30S0000AABBCCDD+1P00400000002B+S12345678")
creds.admin_password   # -> "AABBCCDD"
creds.config_password  # -> "AABBCCDD-12345678"

Exceptions

Exception	Raised when
OpusError	Base class
OpusConnectionError	Network-level failure
OpusAuthError	HTTP 401 from gateway
OpusApiError	HTTP 4xx/5xx other than 401
