MQTT Configuration Issues in PaperUI

General
1

Hello everyone, I’m facing an issue with my openHAB Docker installation. Previously, my MQTT configurations were displayed almost instantly in PaperUI, but now they’re missing. This is affecting my ability to control devices through BasicUI. Let me share my setup and logs for clarity.

Setup Details:

  • Hardware: Raspberry Pi 3+, 1 GB RAM, 32 GB MicroSD
  • OS: 2020-02-13-raspbian-buster (updated via apt-get)
  • Java Runtime Environment: Unknown
  • openHAB Version: 2.5.12 (Docker container)
  • MQTT Binding: binding-mqtt - 2.5.12

MQTT Broker Configuration:

  • Running on localhost without SSL.

Issue:
MQTT configurations in my .things file are no longer showing up in PaperUI, while other configurations remain visible. For example, my ASUS router and IoT devices are still recognized, but MQTT devices like IoT_Steckdose_1 are missing.

Logs:

  • events.log shows nothing unusual.
  • openhab.log only indicates a refresh of the model 'My_things.things'.

Configuration Example:
plaintext
Thing mqtt:topic:IoT_Steckdose_1 “Steckdose | MQTT | Küche” (mqtt:broker:357ze2x2) {
Channels:
Type switch : PowerSwitch “Schalter” [stateTopic=“stat/IoT_Steckdose_1/POWER”, commandTopic=“cmnd/IoT_Steckdose_1/POWER”, on=“ON”, off=“OFF”]
Type number : Power “Stromverbrauch” [stateTopic=“tele/IoT_Steckdose_1/SENSOR”, transformationPattern=“JSONPATH:$.ENERGY.Power”]
}

Attempts to Fix:

  1. Restarted openHAB and Docker containers.
  2. Verified MQTT broker connectivity.
  3. Checked .things file syntax.
  4. Tested direct MQTT commands, which work.

Request:
Has anyone encountered a similar issue? Any suggestions on how to resolve this would be greatly appreciated! :blush:
