Discovering Zigbee2MQTT

In this article:

What is Zigbee2MQTT?

Zigbee2MQTT is open-source software designed to enable communication between Zigbee devices and a home automation server, such as Home Assistant or Node-RED, using a USB Zigbee dongle. It enables control of a variety of Zigbee devices, such as light bulbs, switches, motion sensors and smart plugs, without the need to use manufacturers’ proprietary gateways.

How does it work?

It is based on a USB Zigbee dongle, which acts as a gateway between Zigbee devices and the home automation server. Once connected to a computer or compatible device, the Zigbee dongle communicates with the Zigbee devices on the network.

Zigbee2MQTT uses an MQTT (Message Queuing Telemetry Transport) communication protocol to transfer data between Zigbee devices and the home automation server. Zigbee devices send messages to the Zigbee gateway, which then forwards them to the home automation server via MQTT. Similarly, the home automation server can send commands to the Zigbee gateway, which forwards them to the Zigbee devices concerned.

To configure Zigbee2MQTT , users need to install the software on a computer or compatible device, connect the USB Zigbee dongle, then associate Zigbee devices with the gateway following the instructions provided. Once configured, Zigbee2MQTT offers complete control and automation of Zigbee devices via the home automation server.

Why is it useful?

Zigbee2MQTT offers several advantages over manufacturers’ proprietary Zigbee gateways:

  1. Flexibility: Zigbee2MQTT is compatible with a wide range of Zigbee devices from different manufacturers, offering greater flexibility and interoperability.
  2. Cost: Using a USB Zigbee dongle and open-source software, Zigbee2MQTT is a more cost-effective solution than proprietary gateways, making it accessible to a wider range of users.
  3. Local control: Unlike manufacturers’ cloud gateways, Zigbee2MQTT enables local control of Zigbee devices, offering greater privacy and independence from third-party cloud services.
  4. Customization: Zigbee2MQTT is fully customizable, enabling users to adjust settings to suit their needs and create advanced automations via the home automation server.

In short, it is a versatile and affordable home automation solution that enables a wide range of Zigbee devices to be controlled via a home automation server, offering flexibility, local control and greater customization than manufacturers’ proprietary Zigbee gateways.

Zigbee2MQTT has revolutionized home automation by offering an open-source, affordable alternative for controlling Zigbee devices. By enabling seamless communication between Zigbee devices and a home automation server via a USB Zigbee dongle, it offers unrivalled flexibility, local control and customization, making it a popular choice among connected home enthusiasts.
