Aqara BLE
Autonomous control of Aqara Bluetooth Low Energy locks from Python — no app, no phone — reconstructed by reverse-engineering the official application's observed behaviour. The U200 is the fully solved reference device.
Goals
- Document the Aqara BLE + cloud protocol precisely enough to reproduce it.
- Provide a cross-platform Python library that exposes the lock's full operation surface.
- Enable a native Home Assistant integration (the primary target).
- Make porting to other Aqara-family devices a methodical, repeatable process.
Quick start
Two ways in — a terminal command and an importable API. Integrations couple to the API; the CLI is just a thin adapter over that same API.
Terminal — the aqara command
pip install -e . # puts `aqara` on your PATH
aqara login # account login only (no radio)
aqara scan --transport bleak
aqara lock --transport bumble --port serial:/dev/cu.usbmodemNNNN,115200
aqara unlock ; aqara operate keepalive
Credentials come from --account/--password or the environment/.env
(AQARA_ACCOUNT, AQARA_PASSWORD, AQARA_APPID, AQARA_APPKEY,
AQARA_CLIENT_ID, AQARA_PHONE_ID, AQARA_DEVICE_ID).
Library — the coupling surface for integrations
from aqara_ble import BleakTransport, CloudAuthManager, U200Client
auth = CloudAuthManager(
account=..., password=..., appid=..., appkey=..., client_id=..., phone_id=...
)
async with await U200Client.connect(
auth=auth, transport=BleakTransport(), device_id="lumi1.xxxx"
) as lock:
await lock.lock()
The facade logs in (and re-authenticates on token expiry), scans and identifies
the lock by what it advertises, connects, discovers services and runs the
authenticated operation. Swap BleakTransport() for
BumbleTransport("serial:/dev/…") to drive an ESP32‑S3 controller
(firmware). Shell equivalent:
python examples/lock_cli.py --transport bleak lock.

- docs/devices/u200/validation.md — run it against a real U200 (facade, transports, troubleshooting).
- docs/architecture.md — how it works end to end and the transversal-vs-device Layer Map.
- docs/porting-guide.md — the numbered process to bring a new device online, with the CRC and login obstacles solved up front.
- CONTRIBUTING.md — Spec-Driven Development workflow and the secret-hygiene rules.
Secrets — non-negotiable
No real secret, capture, or app source ever enters this repository. Credentials
and device identifiers live only in a local, git-ignored .env (see
.env.example); raw captures live under a git-ignored captures/
tree. See Constitution Principle I in
