Popup by Itemstate or Itemvalue


i want to have a popup message on habpanel that is triggered by an itemvalue, to get a message when a window is open for more than 20 minutes. A rule set the switch item ‘windowcheck’ to ‘ON’ after 20 minutes.

I tried this https://community.openhab.org/t/custom-popups/24889/2?u=hden

and this https://community.openhab.org/t/how-to-pass-in-and-return-data-from-a-modal/39333/2?u=hden

in combination with ng-if, but every try ends with a infinite loop
can anyone help me??
