I guess this works fine on a mobile screen, but it feels a bit “odd” on a proper screen. Also, there’s a broke…

WebRTC stopped working in UniFi. I reworked everything according to the manual for the new scheme. I receive all snapshots/images, but on the URL where, according to the manual, the stream should be available, I get a 415 error saying that POST is not allowed. When I try to open the same URL with GE…

When I moved the named rule into a separate file and call it, I now get a slightly different error message. error updating camera ParkingCamera java.lang.IllegalStateException: Multi threaded access requested by thread Thread[#71179,OH-rule-UPDATE_CAMERA-1,5,main] but is not allowed for language(s)…

This failure makes any subsequent features fail to install as well. Installations with ma…

Yeah I thought about clearing the cache afterwards, but had no effect. Dev tools in the browser does turn up errors. There’s a recurring failing HTTP request: Request URL: https://192.168.0.26:8443/rest/events?topics=openhab/items/null/command Request Method: GET Status Code: 401 Unauthorized I …

Can you set any Item as UI Command Item in Help & About and retry? Or if you are on a desktop browser, try to go to Application → Local Storage in the dev tools and clear everything from openHAB there.
