zigpy-znp
A library for zigpy which communicates with TI ZNP radios
Decision gist · record as of 2026-08-14
Yes, if you have a compatible TI Zigbee radio adapter and want to use it with Home Assistant or a zigpy-based application. The package is actively maintained, has no known vulnerabilities, and integrates seamlessly with Home Assistant's ZHA. The GPL-3.0 copyleft license is standard for home automation projects. Install friction is low and dependencies are minimal. Not applicable if you use a different Zigbee radio vendor or do not need Zigbee support.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.11 or later.
- Needs a compatible Texas Instruments Zigbee radio adapter (CC2652, CC1352, CC2538, or CC2531) connected via USB or GPIO.
- Low install friction with a pure-Python wheel distribution.

What it is and what it does
zigpy-znp is a Python driver that bridges Texas Instruments ZNP (Zigbee Network Processor) radio modules to the zigpy Zigbee stack. It enables direct communication with Zigbee devices like Philips Hue, IKEA Tradfri, Xiaomi/Aqara, and others through compatible home automation software, most commonly Home Assistant's ZHA (Zigbee Home Automation) integration.
The package provides both a library interface for programmatic control and command-line tools for network management, firmware flashing, and diagnostics. It supports a range of TI hardware from older CC2531 sticks to newer CC2652 and CC1352 modules, though newer hardware is recommended for larger networks. Installation is straightforward via pip, and the package integrates transparently with Home Assistant when the ZHA component is installed.
Use it for
- Control Zigbee smart home devices (lights, switches, sensors) through Home Assistant without a separate Zigbee hub.
- Flash and manage firmware on TI CC2531 or CC2652 Zigbee radio adapters using built-in tools.
- Back up and restore Zigbee network configuration and device information via JSON export/import.
- Perform network diagnostics such as energy scans to detect interference or active beacon scans for network discovery.
- Integrate custom Zigbee automation logic with zigpy in a Python environment.
