Bluetooth control of Yale and August locks
Decision gist · record as of 2026-08-14
Yes, with conditions. Install if you need BLE control of Yale or August locks in a Python application and accept GPL-3.0-only licensing. The low install friction, active maintenance, and healthy user base suggest it works in practice. Pre-Alpha status means the API may change; pin the version or monitor releases. No known vulnerabilities as of 2026-08-14.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.11+.
- Requires a compatible Yale or August lock within BLE range.
- BLE adapter must be present on the host system.

What it is and what it does
yalexs-ble is a Python library that communicates with Yale and August smart locks over Bluetooth Low Energy (BLE). It abstracts the BLE protocol and cryptographic handshake required by these locks, allowing developers to integrate lock control into Python applications—typically for home automation, access control systems, or smart home platforms.
The library depends on bleak for cross-platform BLE communication, bleak-retry-connector for resilient connections, cryptography for authentication, and async-timeout and lru-dict for performance. It targets modern Python (3.11+) and is actively maintained but marked Pre-Alpha, indicating the API may still evolve. With substantial monthly downloads, it serves a real user base despite its early status.
Use it for
- Home automation platforms integrating Yale or August locks into a unified control system
- Building access control applications that unlock doors via BLE from a central Python service
- Smart home scripts that lock/unlock doors based on time, location, or other triggers
- IoT gateways bridging BLE locks to cloud platforms or local networks
