Zigbee2MQTT

Zigbee2MQTT at a glance

Zigbee2MQTT is a popular open-source bridge that connects Zigbee smart-home devices to MQTT, freeing them from proprietary hubs — widely used in self-hosted home automation. It ships frequent releases plus fixes; as software bridging physical devices, keeping it current matters.

For admins Zigbee2MQTT moves quickly, so keep it current for device support and fixes, but read the changelog before updating, since breaking changes happen — back up the configuration and device database (the pairing state) first, as re-pairing devices is tedious. It connects to an MQTT broker, which should be secured (authentication, not exposed), since it can control physical devices (locks, switches). After updating, verify that devices report and respond. Because it controls real-world hardware, treat availability and access seriously. It commonly pairs with Home Assistant. Track releases and their breaking-change notes; patchletter surfaces new Zigbee2MQTT versions so fixes and device support land.
