Since it was not quite easy to set up the software for the Conbee (or Raspbee) on an OrangePi One here a small HowTo:
I used Ambian as my operating system.
Copy this to the SD card with a program of your choice. The first start of the program will take a few minutes because the SD card will be extended first.
Then access the OrangePi as root with ssh (Windows e.g. with Putty) Linux in a console with the command:

ssh (replace with the IP of the OrangePi)

Password is 1234.
First you have to set a new root password and assign a new username.
After that you have to update everything:

sudo apt update
sudo apt upgrade
Now's the time to reboot:
sudo reboot

After that we can install Docker CE for Arm Processors.

curl -fsSL -o
sudo sh
sudo usermod -aG docker your-user

Now install the Decoz container:

docker run -d \
    --name=deconz \
    --net=host \
    --restart=always \
     -v /opt/deconz:/root/.local/share/dresden-elektronik/deCONZ \
    --device=/dev/ttyUSB0 \

We can skip the point “Configuring Raspbian for RaspBee”.

With the command:

docker logs deconz

we can see the Conbee’s expenses. Interesting is if there is a firmware update.
Then there is this:

GW update firmware found: /usr firmware/share/deCONZ/firmware/deCONZ_Rpi_0x261e0500.bin.GCF
GW firmware version: 0x261c0500
GW firmware version shall be updated to: 0x261e0500

Then you have to update the firmware:

docker stop deconz
docker run -it --rm --entrypoint "/" --privileged --cap-add=ALL -v /dev:/dev -v /lib/modules:/lib/modules -v /sys:/sys marthoc/deconz

Please follow the instructions of the skrip.

Then restart the container:

docker start deconz

Now you can access the web interface from the Phoscon-GW software by entering the IP address of the OrangePi.
