brink-flair-modbus

A Python library for reading and writing Brink Flair (and compatible) ventilation units over Modbus, on top of modbus-connection. It follows the spec given by brink.

Usage

BrinkFlair contains the full implementation of the devices capabilities. It uses a ModbusUnit for connection with the device.

import asyncio

from modbus_connection import ModbusTcpParams
from modbus_connection._protocol import ModbusUnit, connect

from brink_flair_modbus import BrinkFlair


async def main() -> None:
    unit: ModbusUnit = await connect(ModbusTcpParams(host="192.0.2.10", port=502))
    device = BrinkFlair(unit)

    await device.async_update()
    print(device.info.model)  # "Brink Flair 300"
    print(device.measurements.supply_temperature)
    print(device.flow_limits)  # (FlowLimits(300, 280))

    await unit.close()


asyncio.run(main())

Development

Requires Python 3.12+ and uv.

uv sync --extra dev
uv run ruff check .
uv run mypy brink_flair_modbus
uv run pytest
uv build

Type checking (mypy --strict) and linting (ruff) are enforced in CI.
