Hi all…I am going crazy!
Since Update to 2.4 (at least as far as I remember) I have the issue that when I open the Sitemap, then close the browser (basically switch to an other app or press the home button) and open the browser again (with the sitemap still on) I have the message “Offline: Waiting for Connection to become available” is shown for about 30 seconds. During that time no updates are made (for the current displayed values). This is extremely anoying.
I thought that has maybe to do with some bindings or some misconfiguration (and played around a lot), but today I setup a totally fresh system (openhabian), just installed the hue binding, added 4 items to the sitemap and again I am having this issue.
It is in Safari and in Firefox (for IOS).
Unfortunatelly I do not have any debug tools on the Iphone…
Added: This behaviour does not appear on the chrome browser in my linux machine.
