Hi everyone,
After upgrading to OpenHAB 4.3, I’ve encountered an issue where the sliders for all MQTT dimmer items are no longer functional in the graphical interface. The dimmers cannot be controlled via the UI and appear stuck at zero. However, the system continues to work perfectly through rules and voice assistants.
Interestingly, only the sliders are affected: switches and color wheels for other MQTT items function normally. I have also tried creating a completely new thing with its associated dimmer item, but the slider remains stuck.
Furthermore, I noticed that when I adjust the slider in Zigbee2MQTT, the numerical percentage value of the slider changes in OpenHAB, but the slider’s knob remains at zero and does not move. Similarly, when I use a group command to control the individual dimmers, the numerical values update, but the slider’s knob still doesn’t move. Additionally, the sliders no longer display the graduated scale.
It’s worth mentioning that dimmers from other bindings are working correctly, so this issue appears to be specific to MQTT dimmer items. Before the upgrade, everything was working perfectly. If there are any parameters I should check or settings to verify, please let me know which ones could potentially be causing this issue.
I would also like to take this opportunity to thank the community for all the hard work and the invaluable support you provide. It’s always appreciated!
Thanks in advance for your help!
