Zigbee2MQTT

In this article, I will be comparing two of the most popular open-source Zigbee gateways: Zigbee2MQTT and ZHA (Zigbee Home Automation). Just like Home Assistant, ZHA uses an open-source Python library, while Zigbee2MQTT is written in JavaScript/TypeScript. Both applications are used for the same purpose, but their setup and integration with Home Assistant differ greatly.

Various large brands and manufacturers are now making and/or selling Zigbee devices like light bulbs, switches and sensors.

Philips, Innr, Ikea, Gledopto, MiBoxer/Tuya

For example: IKEA Tradfri, Philips Hue, Xiaomi / Agara, Trust, Heiman, OSRAM, LEDVANCE, Lutron, Legrand Netatmo,Innr, Gledopto, MiBoxer, SALUS/Computime, Sengled, Schneider Wiser, Tuya, etc..

Zigbee2MQTT

Allows you to use your Zigbee devices without the vendor's bridge or gateway.

It bridges events and allows you to control your Zigbee devices via MQTT. In this way you can integrate your Zigbee devices with whatever smart home infrastructure you are using.

Zigbee2MQTT Architecture

Installing MQTT on Raspberry Pi(debian 11 os)

Installing Zigbee2MQTT  on Zigbee adapter ( SONOFF Zigbee 3.0 USB Dongle Plus)

MQTT broker: MQTT is another smart home protocol that pretty much all tools in this space understand.

Zigbee2MQTT Zigbee adapter : This (also open source) software connects your Zigbee network on the one hand (via the Zigbee USB stick) to your MQTT broker；

on the other hand thus bridging the divide between Zigbee and LAN/Wifi.

Zigbee2MQTT  on Zigbee adapter ( SONOFF Zigbee 3.0 USB Dongle Plus) need a so called MQTT broker that will store and forward messages from devices. 

Home Assistant will subscribe to this broker to receive updates from the devices and send messages to them via the broker.
