Python: Nespresso BLE

Asynchronous Python client for controlling and reading Nespresso coffee machines over Bluetooth Low Energy.

About

This package allows you to control and read Nespresso coffee machines over Bluetooth Low Energy.

Supports the three Nespresso Bluetooth hardware families:

• Barista (Original line)
• Vertuo Next (Venus line)
• Vertuo Mini (VMini)

The machine family is detected automatically from the advertised BLE service UUID. State is exposed through a fully typed NespressoDevice model.

Installation

pip install nespresso-ble

Usage

import asyncio
import logging

from bleak import BleakScanner

from nespresso_ble import NespressoBluetoothDeviceData, is_supported


async def main() -> None:
    device = await BleakScanner.find_device_by_filter(
        lambda d, adv: is_supported(adv.service_uuids)
    )
    if device is None:
        return

    client = NespressoBluetoothDeviceData(logging.getLogger())

    # One-shot poll.
    machine = await client.update_device(device)
    print(machine.status, machine.water_hardness)

    # Or subscribe to live push updates.
    await client.stream(device, lambda m: print(m.status))


asyncio.run(main())

Changelog & Releases

This repository keeps a change log using GitHub's releases functionality. The format of the log is based on Keep a Changelog.

Releases are based on Semantic Versioning, and use the format of MAJOR.MINOR.PATCH. In a nutshell, the version will be incremented based on the following:

• MAJOR: Incompatible or major changes.
• MINOR: Backwards-compatible new features and enhancements.
• PATCH: Backwards-compatible bugfixes and package updates.

Contributing

This is an active open-source project. We are always open to people who want to use the code or contribute to it.

We've set up a separate document for our contribution guidelines.

Thank you for being involved! :heart_eyes:

Setting up development environment

This Python project is fully managed using the uv dependency manager. But also relies on the use of NodeJS for certain checks during development.

You need at least:

• Python 3.13+
• uv
• NodeJS 12+ (including NPM)

To install all packages, including all development requirements:

npm install
uv sync --all-groups

As this repository uses the prek framework, all changes are linted and tested with each commit. You can run all checks and tests manually, using the following command:

uv run prek run --all-files

To run just the Python tests:

uv run pytest

Attribution

This library builds on the reverse engineering work of several projects. Huge thanks to their authors:

• renaudallard/homeassistant_nespresso_smart — reverse engineered the Nespresso Smart Android app, documenting the VMini (Vertuo Mini), Vertuo Next and Barista GATT services, characteristics, state encodings and authentication. Its protocol documentation is the basis for the parsing in this library.
• bulldog5046/ha_nespresso_integration — reverse engineered the Original line (Expert/Prodigio) protocol, auth/ onboarding flow and brew commands via BLE captures.
• tikismoke/home-assistant-nespressoble and everyone before them who helped decode the Nespresso BLE protocols.
