Domoticz

Hi,

I connected an Sonoff ZigBee 3.0 USB-Dongle Plus-E ZBDongle-E at my raspberry pi with Domoticz.
Install the plugin zigbee2mqtt.

In Domoticz at the zigbee2mqtt plugin the next fields:
MQTT server address: localhost
Poort: 1883
Zigbee2Mqtt Topic: zigbee2mqtt

In the configuration.yaml the next:
base_topic: zigbee2mqtt
server: 'mqtt://localhost'

In the Zigbee2MQTT API Transport I see this:
2025-01-29 16:13:52 {"type": "response", "requestId": 5, "isError": false, "payload": []} Zigbee2MQTT
2025-01-29 16:13:52 {"type":"request","requestId":5,"command":"groups_get","params":{}} my username of domoticz (IP: 192.168.178.26)
2025-01-29 16:13:52 {"type": "response", "requestId": 4, "isError": false, "payload": []} Zigbee2MQTT
2025-01-29 16:13:52 {"type":"request","requestId":4,"command":"devices_get","params":{}} my username of domoticz (IP: 192.168.178.26)

In the log of Domoticz I see this:
2025-01-29 16:11:18.115 Error: Zigbee2MQTT: Failed to connect to: localhost:1883, Description: Connection refused
2025-01-29 16:11:18.115 Error: Zigbee2MQTT: Disconnected from MQTT Server: localhost:1883
2025-01-29 16:11:28.131 Error: Zigbee2MQTT: Failed to connect to: localhost:1883, Description: Connection refused

What going wrong here?
Who can help me?

MQTT not (correct) installed/configured:

https://randomnerdtutorials.com/how-to- ... pberry-pi/

If you start with Zigbee2MQTT it is better to directly move to the Domoticz MQTT AutoDiscover hardware gateway instead of the python plugin. I dont think there is a lot of maintenance on the plugin recently.

See wiki https://wiki.domoticz.com/Zigbee2MQTT

Fine!
The mosquitto errors in the log are solved.
I again installed mosquitto.

With the zigbee2mqtt plugin no zigbee sensors wil disappear. Pairing will not happen.

I will now try with the "MQTT Auto Discovery Client Gateway with LAN interface".

In the I copy:
homeassistant:
# Enable the integration (default: false)
enabled: true

What is the right configuration.yaml?

In domoticz in the "MQTT Auto Discovery Client Gateway with LAN interface".
Remote address: localhost
Poort: 1883
Gebruikersnaam: empty
Wachtwoord:empty
Automatische ontdekking voorvoegsel: homeassistant

Now how I get this screen under Alternative 1: Use Domoticz MQTT Autodiscover??
https://wiki.domoticz.com/Zigbee2MQTT

Enter the MQTT broker details real IP address (do not use localhost or 127.0.0.1) and port (eg 1883).
What IP address and port number then?

How can I control if domoticz see my sonoff dongle? Port number?

Jack

Zigbee pairing has nothing to do with mqtt or Domoticz!!

Check the zigbee2mqtt settings and options as that application is connecting with the zigbee2mqtt usb stick.
https://www.zigbee2mqtt.io/

If zigbee2mqtt user interface shows nodes/ devices but in Domoticz no devices then check MQTT if zigbee2mqtt is sending data.

I start with a fresh installation of zigbee2mqtt.

https://www.zigbee2mqtt.io/guide/instal ... installing

# Set up Node.js repository, install Node.js, pnpm and required dependencies
# NOTE 1: Older i386 hardware can work with [unofficial-builds.nodejs.org](https://unofficial-builds.nodejs.org/do ... e/v20.9.0/ e.g. Version 20.9.0 should work.
# NOTE 2: For Ubuntu see tip below
# NOTE 3: Curl might have to be installed first via apt update && apt install curl
sudo curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
sudo apt-get install -y nodejs git make g++ gcc libsystemd-dev
npm install -g pnpm

After copy/past and run in putty of "nmp install -g pnpm" i get errors. (o.a. access denied).
Will not accept: npm install -g pnpm

After "pnpm --version", -bash: pnpm: command not found.

After "node --version", I see V20.18.2

After "pnpm i --frozen-lockfile", -bash: pnpm: command not found.

What going wrong here?

Jack

Alternative is the docker way of installing zigbee2mqtt.

No an another solution?
Is npm and pnpm both necessary?
And when it install seperately?

I think you need to use: sudo npm install -g pnpm

Wim, you are an angel!!

pnpm run build

No errors now!

Tomorrow the next step

Jack

Hi,

We continue

After:
cd /opt/zigbee2mqtt
pnpm start

I see in putty the next:
Starting Zigbee2MQTT without watchdog.

After several seconds:
Error: listen EADDRINUSE: address already in use :::8080
DELIFECYCLED Command failed with exit code 1. (in red text)
p1@raspberrypi: /opt/zigbee2mqtt $

which settings are not correct??

In domoticz I use: MQTT Auto Discovery Client Gateway with LAN interface
Remote address: localhost
Poort: 1883
Automatische ontdekking voorvoegsel: homeassistant

Add this in the configuration.yaml
# Optional: Home Assistant integration (MQTT discovery)
homeassistant:
# Enable the integration (default: false)
enabled: true

Jack

You probably have set port 8080 for Domoticz web-interface as well as for Z2M frontend. So you have to change the Z2M frontend port in configuration.yaml.

which port number can I choose?

Zigbee2mqtt see my Sonoff Dongle.

When I type in putty: $ ls -l /dev/ttyUSB0
I see: crw-rw----1 root dialout 188, 0 Jan 30 16:52 /dev/ttyUSB0

When I type in putty: ls -l /dev/serial/by-id
I see: lrwxrwxrwx 1 root root 13 Jan 30 16:52 usb-ITead_Sonoff_Zigbee_3.0. and more

After:
cd /opt/zigbee2mqtt
pnpm start

I see some errors about the adapter.
-Configuration is not consistent with adapter state/backup!
-Please update configuration to prevent further issues.
-And more.

When in de configuration.yaml "homeassistant" change from false to true and save.
After reboot it change again in false.

Whats happens here?

Jack

Also check the zigbee2mqtt forum for the errors you see: https://github.com/Koenkk/zigbee2mqtt/discussions

For the Sonoff Dongle Plus-E I add the next in the configuration.yaml

serial:
adapter: ember # (is the right? Or zstack?)
port: /dev/ttyUSB0

After:
cd /opt/zigbee2mqtt
pnpm start

The following errors disappear:
-z2m Error while starting zigbee-herdsman
-z2m Failed to start zigbee-hersman

Jack

Use adapter type: zstack.

Next: specify the right adapterport: here
