Using openHAB as backend to cometVISU


I’m trying to get familiar with cometVISU/openHAB on a Raspberry Pi. I’ve installed the demo described on this page: and changed the items in cometVISU.items so that they are consistent with visu_config.xsd.

However, the switch “Corridor GF” will not update when I click on it, only after manually refreshing the page in the browser by pressing F5.

What I am doing wrong?

Thanks for the help!
