xbloom-py

Async Python library for xBloom Studio coffee brewers: the BLE protocol, recipe validation, over-the-air firmware updates, and the optional cloud account API.

Unofficial, and not affiliated with or endorsed by xBloom. See Disclaimer.

Install

pip install xbloom-py            # pure-python core: spec, recipes, validation
pip install "xbloom-py[ble]"     # + local Bluetooth control
pip install "xbloom-py[cloud]"   # + cloud account, recipe sync, firmware check
pip install "xbloom-py[all]"     # everything

Import as xbloom:

from xbloom import spec, recipe_validate

Dependencies are declared with lower bounds only and no upper pins, so the package drops into an environment that already pins these without fighting it.

What is in it

ble, ota and mode_listener import their Bluetooth dependencies lazily, so they can be imported for packet construction with no extras installed.

Development

uv sync --all-extras
uv run pytest

The suite runs without extras too; test_cloud.py is skipped when aiohttp and cryptography are absent.

Firmware updates

Read this before you use ota. Firmware flashing is the one thing in this library that can permanently damage your machine. Use it only if you accept that.

ota verifies the update's MD5 before anything is sent, and every block is acknowledged by the machine as it is written. That makes a bad flash unlikely — it does not make it impossible. Bluetooth is a wireless link, and a wireless link can drop. If it drops in the middle of a firmware write, the machine can be left unbootable, with no way to recover it over BLE.

If you choose to use it:

• Keep the machine powered and close to the Bluetooth adapter for the whole flash.
• Never start a flash during a brew.
• Don't kill the process, or let the host sleep, while one is running.

You do this entirely at your own risk. This is unofficial software talking to an undocumented protocol that was worked out by inspection, and it is not endorsed by or connected to xBloom in any way. The authors and contributors accept no responsibility and no liability for any damage to your machine, loss of warranty, or any other loss arising from using this library — the firmware updater above all. If that isn't a risk you want to take, don't import ota; everything else works without it.

Disclaimer

This is an independent, community project. It is not affiliated with, authorized, or endorsed by xBloom. "xBloom" is used only to say which machine this talks to. It communicates with the machine over its local BLE protocol, worked out for interoperability, which may change at any time with a firmware update and break this library without warning.

The software is provided as is, without warranty of any kind, express or implied. You use it at your own risk, and the authors and contributors are not liable for any damage, loss, or injury resulting from its use. See the Firmware updates section for the risk that matters most.
