MQTT Broker for Zigbee2MQTT works / Another Device with on the same Broker fails

Version: 2.5.9 (Build)
Raspberry PI 4

Hi Team,

i just installed zigbee2mqtt with mosquitto and everything works without problems.
Now I finished my solarcontroller that publishes all data to the same mosquitto broker.

I just see the state descriptions and the subscription:

The PaperUI shows no panel, the BasicUI shows the panel without data.

I cannot solve the problem… Any Ideas?

Example of the Payloads:
The Device has

  • 6 RTD Ports
  • Onewire.
  • 4 Relais
  • 2 ports to messure impules from the flow sensors
    Is it possible that one thing can only have one temperature port?

Thanks in advance

Have you created a new thing for your device so openHAB know’s what it is? Can you share your thing

Of course can I share the Device:

Here the things:

I tried a lot of things to get it working, but still no success…

Thanks in advance!

I autogenerated them using the openHAB extention of VS Code

Great, now I have a panel.

I should see data, but the panel show no data, I can clearly see that my solarcontrol sends updates every few minutes.

Thanks for the great help.

So its all working? My german not good

Please use code fences - sandwich your code between three back ticks: ```

like this

Here you have shown that your solarcontrol Thing is inside your MQTT bridge definition. But in your OP you mention that you also use zigbee2mqtt, and that it works. Are your zigbee2mqtt Thing configurations inside the same MQTT bridge? Or have you defined a second one, and given it a different name?

Where are these lines copied from: output from your solar device, or output from Mosquitto? (Have you confirmed that your solar device is connected to Mosquitto?)

Yes, I have my solarcontrol in the same bridge as the zigbee2mqtt. It is the same mqtt broker.
Now the panel is working but no MQTT data is shown in the panel…
I try to fix it…

I keep you informed…

Thanks fpr the great help!

I just restarted openhab2 and the panel is working.

Now I can implement the switches - Great!!!

I leave the cosmetics like formatting out for the moment…

denominator told me that he generated the items…
Is there a tutorial about the VS code?
I also use openhab extensions, but I have no idea how to use it properly.


PaperUI is designed for administering openHAB itself, it shouldn’t really be used for controlling your devices. Use Sitemaps (displayed in BasicUI or the phone apps) for controlling your devices, or HABPanel. There you can change the formatting easily!

In vscode open an items file. Goto extention and right click on a thing and then create items from thing.

Yeah and after changing mqtt things sometimes you need a restart.

Thanks again, I installed openhab in visual studio, I try to generate the items next time.

Yes, it works perfect. Still a lot to do. My solarcontrol needs also some work, I just will use openhab to monitor the device to get errors when something gets wrong. The device should work even when OH2 is down.

If you are interessted I would share the complete solarcontrol project. Schematics and also the python code. It uses mostly SMD parts and breakout boards from china that are making the RTD conversation. (PT1000 or PT100) in 4 wire configurations.
