Hi, I migrated to OH3 during holidays. Atm I am building up my semantic model using files. So far everything is fine except that the UI displays the model wrong. Not always but over and over again. e.g. Group gLaundryroom "Laundry" <washingmachine> (gGroundFloor) ["LaundryRoom"] Group gLaund…

I just rebooted the server again and everything seems to be fine. Even though I didn’t change anything? … I hope it lasts. Thanks!

[image] Willp: But the “laundry error” persists (it popped up after a restart of OH3 without changing anything). Have you defined any part of the Semantic Model using only the UI? That can cause unpredictable things to happen after a restart… Also Blinds is an Equipment type, which you’ve us…

Hi, just a guess. You have assigned the blind to two groups. Do you have the same behavior if you remove the second group temporarily?

[image] hafniumzinc: Have you defined any part of the Semantic Model using only the UI? That can cause unpredictable things to happen after a restart No, only file based. And as I wrote: the display error occurred after a restart!? Another equipment showed up wrong before but vanished.

[image] thefechner: Hi, just a guess. You have assigned the blind to two groups. Do you have the same behavior if you remove the second group temporarily? Yes, tried that without success.

[image] hafniumzinc: Also Blinds is an Equipment type, which you’ve used twice here - so you’re trying to add an Equipment to an Equipment to a Location: is that what you meant to do? It’s not wrong, but there’s no Points/Properties here. Ok. To be honest I’m just following that tutorial Isn…

[image] Willp: Isn’t the Rollershutter a Point? No, it’s not, but you haven’t defined it as a roller shutter Point either. You have used [image] Willp: ["Blinds"] which is an Equipment type, so openHAB will treat it as an Equipment. Have a look at the list linked from that tutorial t…

[image] hafniumzinc: which is an Equipment type, so openHAB will treat it as an Equipment. You’re right! Didn’t think about it. I’m still struggling with the semantic model. But anyway: tried that straight away… no success [model2]

That’s odd. When the model doesn’t display right, select the equipment item then on on the right click its name to go to its page. In “Semantic Classification” do you see a line “hasLocation: gLaundryroom” ?

Ok, we’re getting closer [model] Checked other equipment that is shown correctly and there “hasLocation: …” is set. But what’s the cause? The item definitions are the same!?

I have the same issue on some of my items. They show correctly in locations. One of my doors has group alarm system. and laundry. Shows only in laundry [image] [image]

No, at most one location, or one equipment, or both.

Follow the arrows, there can be only one relationship of each type.
