# Zigbee2MQTT vs ZHA: which Zigbee stack for Home Assistant and beyond

> Both replace vendor hubs with your own coordinator. ZHA is built into Home Assistant; Zigbee2MQTT bridges devices to an MQTT broker and works with Home Assistant via MQTT discovery or with any other MQTT consumer.

Both let you run a Zigbee network from your **own coordinator** instead of vendor hubs. They are alternatives: a coordinator is used by one of them at a time.

| | ZHA | Zigbee2MQTT |
|---|---|---|
| What it is | Home Assistant integration | standalone bridge Zigbee → MQTT |
| Extra infrastructure | none beyond Home Assistant | MQTT broker (e.g. Mosquitto) |
| Works without Home Assistant | no | yes: anything that speaks MQTT (Node-RED, scripts, other platforms) |
| Home Assistant integration | native | via MQTT discovery |
| Non-standard devices | ZHA Device Handlers ("quirks"), Python | converters in zigbee-herdsman-converters; *external converters* (JavaScript) for your own |
| Setup effort | lowest | one more service plus broker |

## How to choose

- **Home Assistant only, want minimal moving parts** → ZHA.
- **MQTT already in use, several consumers, or no Home Assistant** → Zigbee2MQTT.
- **A specific device matters** → check it in *both* device lists before buying or deciding. Support for new, non-standard devices (many Tuya devices) differs between the two and changes with each release.

## Switching later

Moving from one to the other can mean **re-pairing devices**; check the current migration notes of both projects first. Decide early, before you have dozens of devices.

Both stacks depend on the same basics: a good coordinator, a USB extension cable away from interference, a sensible channel and enough routers.

## Claims

- ZHA supports non-standard devices through ZHA Device Handlers ('quirks'), device-specific Python scripts. (unverified)
- ZHA is a Home Assistant integration that connects Zigbee devices directly to Home Assistant through a Zigbee coordinator, without a proprietary gateway. (unverified)
- Zigbee2MQTT integrates with Home Assistant through MQTT discovery. (unverified)
- Zigbee2MQTT bridges Zigbee devices to an MQTT broker and requires a Zigbee adapter, a host to run on and an MQTT broker such as Mosquitto. (unverified)
