Ebus binding does not show heating values of Vaillant VCR 470

  • Platform information:
    • Hardware: Raspberry PI 4/8GB/16GB
    • OS: Raspbian GNU/Linux 11 (bullseye)
    • Java Runtime Environment: openjdk version “17.0.7” 2023-04-18
    • openHAB version: openHAB 4.0.1
  • Issue of the topic: I installed the latest ebus binding (Release 3.4.16) and configured the bridge to use my local ebusd. In the inbox I got 5 things (ebus Standard 04, ebus Standard 08, ebus Standard 15, Vaillant BAI00 08 and Vaillant VRC430(f)/470(f) 15). For every channel of every thing I created an item. I only wanted to see which information the binding provides. But the only information I get are two timestamps. The ebusd log shows, that there is much more information available.

Does anyone has an idea what to do to get the ebusd values in my ebus binding?

For Vaillant polling is required for more data. And you should check the latest version from the main thread as polling was not working with the previous release.

Thanks a lot for the quick answer. Is there a documentation available how to set up polling?
