Quick question - I want monitor all my sensors, regardless of battery state.
Therefore, I use an update state expiration timer that, that sets the item’s state to UNDEF after two hours.
I’m doing this for example on the temperature item of an environmental sensor.
I now want to create a page that shows all the items (or better, their underlying Things) in a list item.
However, I’m not sure how you would create this kind of dynamic lists. Do you create a dynamic item (string), iterate over all items in state UNDEF, extract the Thing label, push it into this string label and display it?
Or is there a way to define scripts/filters on lists widgets?
That’s not possible. Widgets, and most everything else works with Items, not Things.
This. Look at the oh-repeater widget. You can iterate and filter over a Group’s members it all Items with a given tag, filter then and build a list of list item widgets to show.
There’s are several tutorials and examples including the Battery Status widget in the Marketplace.
Further information is on that page and the rest of the UI docs. There is more about filter itself in the oh-repeater reference page in the docs and a number of tourism’s on the forum.
