Introduction
If you’re integrating Zigbee devices into Home Assistant, you’ve likely come across two popular solutions: ZHA (Zigbee Home Automation) and Zigbee2MQTT (Z2M). Both allow you to connect Zigbee devices to your smart home, but they have key differences in compatibility, features, and flexibility. This guide breaks down the pros and cons of each to help you choose the best option for your setup.
What is ZHA?
Zigbee Home Automation (ZHA) is the built-in Zigbee integration in Home Assistant. It provides an easy and user-friendly way to connect Zigbee devices without needing additional software.
? Advantages of ZHA
- Built into Home Assistant – No need for extra installations.
- Simple setup – Plug in your Zigbee coordinator and start adding devices.
- Fast and local – Direct integration with HA, ensuring low latency.
- Supports many Zigbee coordinators – Works with popular options like the SONOFF ZBDongle-P / ZBDongle-E.
- Regularly updated – Maintained within the Home Assistant ecosystem.
? Installation Guide: How to Install ZHA
Home Assistant’s ZHA integration supports all standard Zigbee device types. It should be compatible with most Zigbee devices as long as they fully conform to the official ZCL (Zigbee Cluster Library) specifications defined by the CSA (Connectivity Standards Alliance, formerly the Zigbee Alliance). There is therefore no official compatibility list of devices that will work out-of-the-box with the ZHA integration. Not all hardware manufacturers always fully comply with the standard specifications.

? Limitations of ZHA
- Less device compatibility – Supports many Zigbee devices, but not as extensive as Zigbee2MQTT.
- Limited advanced configurations – Less control over Zigbee network settings.
- No native MQTT support – If you rely on MQTT for automation, you’ll need a separate integration.
What is Zigbee2MQTT (Z2M)?
Zigbee2MQTT (Z2M) is an open-source alternative that connects Zigbee devices to Home Assistant using an MQTT broker. It offers extensive device compatibility and advanced customization.
? Advantages of Zigbee2MQTT
- Widest device compatibility – Supports over 3,000+ Zigbee devices from various brands.
- Full control over Zigbee network – Customize device settings, logging, and network parameters.
- MQTT-based – Ideal for users who integrate with other MQTT-based systems.
- Frequent updates – Community-driven development with active improvements.

? Limitations of Zigbee2MQTT
- More complex setup – Requires installing an MQTT broker (e.g., Mosquitto) and configuring YAML settings.
- Higher learning curve – Advanced features may require some technical knowledge.
- May require firmware updates – Some coordinators need flashing custom firmware for compatibility.
ZHA vs. Zigbee2MQTT: Feature Comparison
Which One Should You Choose?
- Choose ZHA if you want an easy-to-use, built-in Home Assistant Zigbee integration with minimal setup.
- Choose Zigbee2MQTT if you need extensive device support, MQTT compatibility, and advanced customization options.
Conclusion
Both ZHA and Zigbee2MQTT are excellent choices for integrating Zigbee devices with Home Assistant. If you prefer simplicity and direct integration, ZHA is the way to go. However, if you need advanced features and broader device compatibility, Zigbee2MQTT is a powerful alternative.
Still unsure? Try ZHA first since it’s built into Home Assistant. If you later find that a device isn’t supported or needs more advanced features, you can switch to Zigbee2MQTT!
