What hardware is needed to DIY a Zigbee gateway?
When building a DIY Zigbee gateway, several hardware components are required. A brief description of each element is available below.
A Single-board Computer (SBC)
The SBC is the Zigbee gateway’s central component, the system’s brain responsible for running the IoT gateway software and managing the Zigbee network. Popular SBCs for building Zigbee gateways include Raspberry Pi, BeagleBone, and Odroid.

Zigbee Radio Module
The Zigbee radio module is the component that allows the gateway to communicate with Zigbee devices. It must be compatible with the IEEE 802.15.4 standard as it is responsible for transmitting and receiving Zigbee signals. Popular Zigbee radio modules include the CC2531, CC2530, and XBee.
Power Supply
The power supply provides power to the SBC and Zigbee radio module. It should be able to supply enough power to the components, and its voltage should match the requirements of the SBC and Zigbee module. A standard power supply for Zigbee gateways is a 5V micro USB power supply.
Other Components
A microSD card for storing the operating system and gateway software, a USB-to-UART adapter for programming the Zigbee radio module, and a case or enclosure to protect the IoT gateway components.
The Specific Steps of DIY a Zigbee Gateway
Here are the particular actions for DIY a Zigbee gateway:
Assembling the Hardware Components
The first step includes connecting the Zigbee module to the SBC, the power supply, and other required components.
Installing the Operating System (OS) On the SBC
Dusun Zigbee gateway products support many operating systems.Popular options for Zigbee gateways include Raspbian for Raspberry Pi, Debian for BeagleBone, and Ubuntu for Odroid. Users can install the OS on a microSD card or using a pre-built image.
In fact, if you run into some trouble at this step, you can go straight to off-the-shelf Zigbee hubs. Dusun Zigbee gateways support all major OS including, Linux, Ubuntu, Debian, OpenWRT, and Android.
Connecting the SBC to the Internet and Updating the OS
Connect the SBC to the internet to update the operating system. Run the required commands to install the updates to ensure the system is up-to-date with the latest security patches and software updates.
Installing the Zigbee Software On the SBC
Several open-source Zigbee gateway software options are available, including Zigbee2MQTT, ZHA, and deCONZ. Install and configure the software by following the documentation and instructions.

Configuring the Zigbee Software
Configure the Zigbee software by following the instructions in the documentation. It includes setting up the Zigbee network, pairing devices, and configuring device-specific settings.
Connecting the Gateway to the Network
Finally, connect the Zigbee gateway. It involves configuring network settings and setting up port forwarding if necessary. The gateway can control and monitor Zigbee devices once connected to the network.
Is it better to buy a Zigbee gateway or DIY a Zigbee gateway?
Whether to buy or DIY a Zigbee gateway depends on various factors, customization requirements, and particular applications.
Technical Expertise
Users should consider their technical capability before buying or DIYing a Zigbee gateway. DIY Zigbee gateways require strong technical skills for installation, operation, and debugging.
The commercial Zigbee gateways are more straightforward. They are easy to install and maintain. Few IoT gateway vendors also provide add-ons like aftersales service, warranty, and return policy. Buying a Zigbee gateway naturally provides peace of mind and assurance.
Budget
Users should consider their budget when deciding between buying or DIYing a Zigbee gateway. DIY Zigbee gateways can be cost-effective, while commercial ones can be expensive.
With the growth of your device network, commercial Zigbee gateways can be an economical solution. IoT gateway manufacturers mass produce IoT gateways, resulting in less cost even lesser than DIYing.
Customization Requirements
Users should consider their customization requirements when deciding between buying or DIYing a Zigbee gateway. DIY Zigbee gateways offer more customization options, while commercial Zigbee gateways are limited in customization.
Dusun IoT developed a range of customizable commercial ZIgbee gateways to address this limitation. Its Dusun Pi series is an open-source IoT gateway range for IoT developers at all stages, from Prototype to mass production
