Python API for TP-Link Kasa and Tapo devices
Decision gist · record as of 2026-08-14
Yes, if you own TP-Link Kasa or Tapo devices and need to control them from Python or the command line. The library is actively maintained, has low install friction, and covers a broad range of device types. The GPL-3.0-or-later license is permissive for personal and open-source use but requires attention if you plan to distribute proprietary software. No known security vulnerabilities.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.11 or later; devices must be on the same network or reachable by IP address.
- Low friction: pure Python wheel with 5 runtime dependencies (aiohttp, asyncclick, cryptography, mashumaro, tzdata).
- Active maintenance with recent commits; last release 548 days ago but repository shows ongoing development.

What it is and what it does
python-kasa is a community-maintained Python library and CLI tool for discovering and controlling TP-Link Kasa and Tapo smart home devices. It provides both a high-level async API for programmatic control and a command-line interface for direct device management. The library handles device discovery via broadcast, authentication, and feature-based control (turning devices on/off, adjusting brightness, color temperature, and other device-specific settings).
The package is built on async I/O (aiohttp, asyncclick) and supports modern Python versions (3.11+). It works with a wide range of TP-Link hardware including plugs, power strips, wall switches, bulbs, light strips, hubs, and hub-connected devices. The library is not affiliated with TP-Link and relies on community contributions for device support and testing.
Use it for
- Automate smart plugs and switches in a home network via Python scripts or scheduled tasks.
- Build a dashboard or mobile app that discovers and controls multiple TP-Link devices.
- Integrate TP-Link devices into a broader home automation system (e.g., Home Assistant).
- Query device state (power, brightness, color) and log telemetry for monitoring.
- Provision and configure TP-Link devices programmatically before deployment.
