yeelight
A Python library for controlling YeeLight RGB bulbs.
Decision gist · record as of 2026-08-14
Yes, if you own supported YeeLight bulbs and want programmatic control over LAN. The library is stable, has no known vulnerabilities, and installs with low friction. However, it is dormant—expect no new device support or active bug fixes. Verify your bulb model is in the supported list before committing; if you need cutting-edge device support or active maintenance, look for an alternative or fork.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Bulb must have "development mode" enabled via the YeeLight app before the library can connect to it.
- Low friction: pure Python wheel with three lightweight runtime dependencies (ifaddr, importlib_metadata, async-timeout).
- Maintenance status is dormant—last release 563 days ago—so expect no active bug fixes or new device support, though the library remains functional for existing supported models.

What it is and what it does
Yeelight is a Python library for controlling YeeLight WiFi RGB LED bulbs on your local network. It provides both synchronous and asynchronous (asyncio) interfaces to discover bulbs, query their state, and send commands—turning them on/off, adjusting brightness and color temperature, setting effects, and activating music mode. The library handles the low-level protocol communication, abstracting away socket details and command formatting so you can work with simple method calls.
The package depends on ifaddr for network interface detection, importlib_metadata for metadata access, and async-timeout for asyncio timeout handling. It requires Python 3.4 or later and supports a range of YeeLight bulb models (ceiling lights, color bulbs, strips, and dimmable variants). Setup requires enabling "development mode" on your bulb through the YeeLight app first. The library is dormant—last updated 563 days ago—so it works reliably for existing supported models but receives no active maintenance or new device support.
Use it for
- Automate home lighting: turn bulbs on/off, adjust brightness, and change colors based on time of day or events.
- Build a smart home dashboard: query bulb state and send commands from a Python web app or CLI tool.
- Sync lights to music: use the music mode interface to drive bulb effects in response to audio input.
- Discover and control multiple bulbs: use the discovery API to find all YeeLight devices on your LAN and manage them programmatically.
- Integrate with home automation: use the asyncio interface to control bulbs concurrently in larger automation workflows.
