Zigbee2MQTT
Zigbee2MQTT is an open-source (MIT-licensed) bridge that runs a Zigbee network from a USB coordinator dongle and publishes every device over MQTT, making any supported Zigbee device usable in Home Assistant and other platforms without a vendor hub. Its device database — the zigbee-herdsman-converters project — is the most comprehensive public record of Zigbee devices, and the source of the 5,405 Zigbee devices in our dataset.
Each supported device has a community-maintained converter that maps its Zigbee clusters, including manufacturer-proprietary ones, to clean MQTT topics. That is why Zigbee2MQTT frequently exposes features a device’s own hub hides, and why obscure Tuya-derived hardware often works there first. It runs on anything from a Raspberry Pi up, commonly as a Home Assistant add-on, paired with a coordinator like the Sonoff ZBDongle-E or SMLIGHT SLZB-06.
Zigbee2MQTT is a DIY platform: you administer it yourself, and support comes from documentation and community rather than a vendor. We treat “supported by Zigbee2MQTT” as a compatibility signal in its own right — it also strongly predicts ZHA support, since the projects share device knowledge.
