Installation
The deCONZ application is a tool to configure, control and monitor Zigbee networks with the ConBee III.
The following sections describe the installation steps of deCONZ for various platforms.
Supported platforms
Connection
To ensure a strong radio signal, the ConBee III should preferably be connected to a USB 2.0 socket with an USB extension cable.
- Prevents interference with housing and peripherals
- Provides maximum signal range and reliability
Note
Connection problems may occur if the ConBee III is attached directly to the USB port or is located near USB 3.0 devices such as external hard drives or memory sticks.
Raspberry Pi OS
Supported Raspberry Pi models and distributions
- Raspberry Pi (all models, except Pico)
- Raspberry Pi OS
Note
The following steps describe the manual installation of deCONZ. Alternatively a preinstalled SD-card image can be used.
Installing the Operating System
Download and launch Raspberry Pi Imager from the website www.raspberrypi.com/software

Insert the SD card into your PC or an SD card reader.
Raspberry Pi Device: Select your Raspberry Pi model.
Operating System: Select a current operating system.
Storage: Select the SD card drive.
Use OS Customisation: Click
No
if the default settings are acceptable, for example, if you are using an Ethernet cable and have direct access via a connected mouse, keyboard, and monitor. Otherwise, clickYes
to adjust the settings: hostname, username, password, Wi-Fi, time zone, and keyboard layout, and save them withsave
.

To access the Raspberry Pi remotely, i.e., without a connected mouse, keyboard, and monitor, it is important to enable the SSH interface under the
Services
menu. Furthermore, you should assign your own login credentials under Set username and password.Write: Start the copying process
Remove the SD card from the card slot (eject it in Windows Explorer → right-click on the drive letter and select
Eject
)Insert the microSD card into the Raspberry Pi’s SD card slot
Connect the USB cable to the Raspberry Pi. The operating system will start automatically after approximately three seconds and will be ready for use after approximately one minute.
Remote Access
Remote access to the Raspbian OS desktop is via the VNC interface. This must first be enabled after successful operating system installation.
To do this, log in to the Raspberry Pi using a suitable SSH console program via its IP address, with the previously assigned Username and Password, and enter the following command:
sudo raspi-configIn the menu item
3. Interface Options,
set theI3 VNC
option to Enable.Restart the Raspberry Pi
sudo reboot
You can now access the Raspbian OS desktop using a suitable VNC program.
deCONZ Installation

Requirement
- Raspberry Pi 5
- Raspberry Pi OS → Installing the operating system see here
Installation with onboarding (web browser wizard)
This guide is based on the official description of Zigbee2MQTT on Linux.
Installation of MQTT Broker: Instructions
Installation of the necessary environment and Zigbee2MQTT: Instructions
Connect ConBee III to Raspberry Pi
Open the console and run the first start of Zigbee2MQTT
cd /opt/zigbee2mqtt pnpm startOpen the web browser on the Raspberry Pi and start the Zigbee2MQTT onboarding via the address http://localhost:8080
or
Start Zigbee2MQTT onboarding with an external web browser from a PC or laptop via the Raspberry Pi:

Installation via console
This guide is based on the official description of Zigbee2MQTT on Linux.
Installation of MQTT Broker: Instructions
Installation of the necessary environment and Zigbee2MQTT: Instructions
Connect ConBee III to Raspberry Pi and start console
Determine connection port
ls -l /dev/serial/by-id
Note
We recommend using the specific name of the ConBee III as the port instead of just entering the interface ttyUSB0. As soon as this interface changes, e.g. when using a different USB interface, Zigbee2MQTT will no longer work.
Open directory for configuring Zigbee2MQTT
cd /opt/zigbee2mqtt/data/Create configuration file
configuration.yaml
nano configuration.yamlEnter the previously determined connection port, the baud rate
115200
and the adapterdeconz

Connect the ConBee III to your PC/laptop
Perform the update
Done!
Update manually
The firmware of the ConBee III can be updated manually. An tutorial video for the update under Windows is available on Youtube:
Furthermore, the individual steps, also for other operating systems, are described in the FAQ.
Factory reset
The ConBee III could be reset to factory new settings by using the integrated service button.
- Press and hold the button for at least 15 seconds using a pointed object.
- The ConBee III must be plugged into an active USB port. (PC, laptop, mini PC, USB charger)
- This process requires no software like deCONZ or Phoscon App to be active.
The following parameters are reset to factory new settings:
- Restore original MAC address
- Set a random network name (PANID)
- Set radio channel 11
- Set a random network key
