Dusun
This document details how I installed a Mosquitto MQTT Broker and Zigbee2MQTT on my Dusun DSGW-210 IoT Gateway computer. You can see the review of the device here:
I am using this device to be a standalone, self-contained Zigbee2MQTT gateway to integrate Zigbee device to a TapHome home automation system over MQTT. My exact model is a DSGW-210-F18-HA. HA means that it has Home Assistant preinstalled, which I am not going to use in my project.
Also watch my video on this setup if you want to follow along:
For this setup, I recieved support from the Dusun Online Community, especially on the Zigbee adapter configuration for Zigbee2MQTT. You can find my comments in this post: https://community.dusuniot.com/t/i-cant-use-zigbee2mqtt/177. Do not hesitate to contact them if you face problems with their products.
The default password for user root is root on this device. There is also an admin user installed, I will be using the admin user to install Mosquitto and Zigbee2MQTT.
First log in with root/root change the root password with:
passwd root
Also change the default password for user admin with:
passwd admin
Reboot the device with reboot and log in with admin with the new password. We will do the rest of the steps with user admin.
Update Linux to make sure we are up to date:
sudo apt-get update
sudo apt-get upgrade
Change the hostname of the device, default is set to HomeAssistant:
sudo nano /etc/hostname
And now also edit this file:
sudo nano /etc/hosts
Normally in this file the first line reads 127.0.0.1 localhost just type you new hostname after localhost (and a space), and save.
After this reboot again with sudo reboot.
Follow this article to change the local timezone of the machine: https://linuxize.com/post/how-to-set-or-change-timezone-in-linux/. I don't think it is necessary, but it is better to keep in sync with your local time.
I have documented this process already for my main server install: https://github.com/nygma2004/km/wiki/Node-Red-Server#mqtt.
Perform the steps as they are, there should be the same as for my main server. Once everything is running, I test the connection with MQTT Explorer.
Here, we are going loosely follow the instructions I already prepared for my main server: https://github.com/nygma2004/km/wiki/Node-Red-Server#zigbee2mqtt. Please open the page in the link and this page and check in parallel.
First, read the instructions around determining the ID of the serial device. Here we will obviously use the coordinator built into the IoT Gateway, and for me the ID of this device is usb-1a86_USB_Serial-if00-port0. I assume since you get the same hardware it will be the same, but if not, please update the rest of my examples with your ID.
Before we continue, please check if your user has access to the serial device:
test -w /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0 && echo success || echo failure
If the response is success you can skip to the next part, if it is failure please read along.
Give admin access to the serial device:
sudo chown admin /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0
Also give access the user to communication ports:
sudo usermod -a -G uucp $USER
sudo usermod -a -G tty $USER
sudo usermod -a -G dialout $USER
Test the access to the serial device again, and this time the response should be success.
This step is optional, but since I was not planning on using Home Assistant, it was just using system resources and slowing the boot process down. I followed this guide: https://gist.github.com/narfel/035944cbf8475b29621a7a5dff00d97f, and did step 1 and step 2. This just disables the Home Assistant service from starting when the gateway starts. It can be re-enabled again in the future if required.
Please follow my other page, and within that the "Installing" section of this page: https://www.zigbee2mqtt.io/guide/installation/01_linux.html#installing
Once that is done, configure Zigbee2MQTT's configuration file:
nano /opt/zigbee2mqtt/data/configuration.yaml
I configured my file as below:
homeassistant: false
permit_join: false
mqtt:
base_topic: zigbee2mqtt
server: mqtt://localhost
user: YOUR_USERID
password: YOUR_PASSWORD
serial:
port: /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0
adapter: ezsp
frontend:
port: 8085
advanced:
homeassistant_legacy_entity_attributes: false
legacy_api: false
legacy_availability_payload: false
device_options:
legacy: false
Obviously update the userid, password and the serial ID if required.
And now go back to the Zigbee2MQTT installation guide (link above), and complete the "Starting Zigbee2MQTT", and "(Optional) Running as a daemon with systemctl" sections.
At this point Zigbee2MQTT should be running and when you log into the MQTT server with MQTT Explorer, your should see a zigbee2mqtt topic:
With this, the configuration is complete. Have fund using your new Zigbee2MQTT Gateway!
I have purchased a second Dusun gateway which has a different firmware installed on it. It had a firmware with a pre-installed Zigbee software which was blocking the Zigbee2MQTT to access the coordinator. Execute these commands with sudo to kill these apps before starting Zigbee2MQTT.
killall reapp.sh
/etc/init.d/S99bul stop
mv /etc/init.d/S99bul /etc/init.d/bul
mv /usr/bin/bul /usr/bin/bul-b
/etc/init.d/S99zigbee stop
mv /etc/init.d/S99zigbee /etc/init.d/zigbee
mv /usr/bin/AmberGwZ3 /usr/bin/AmberGwZ3-b
