icons and number items

[Victor Belov]

Hi,

Is it possible to display different icons for a number item depending
on the value? For example. I have an outside light sensor and would
like to display it with different icons (sun and moon) together with
current light level value, depending on if the value is less or bigger
then my twilight threshold.

Best regards,
Victor Belov

Hi Victor,

yes and no :-)

It is possible to show different icons subject to the state of an item (see lock-x.png for example). But the state must match exactly. There are no functions (like less or greater than) which could be applied to the getIcon() function. To accomplish your requirement you will have to create a rule which translates the intermediate states to the given threshold values.

Hi,

Haha, I know about icons. The trick is I want to display numeric value!

like an overlay on the leftside icon (already known from iOS?) ?

If not i understood from your explanation that you'd like to show one icon of sun or moon depending on the state of the brightness value.

Hi,

There is one exception to this rule: For Items that are based on a PercentType (e.g. Dimmer or Rollershutter). There, openHAB searches for an icon "rollershutter-<state>.png" and stops only when it finds one (or ends at 0). Example: If the current state is 74, it will check for "rollershutter-74.png", cannot find it, tries "rollershutter-73.png", cannot find it and so on until it finds "rollershutter-60.png" and uses it. That's why you can get a nicely animated rollershutter icon while it is moving. Same for dimmers - it can always display a suitable icon for every percent value.

All this does not help you for Number items, though, sorry :-)

Kai

Hi,

Do you think it makes sense to create an issue for that? :-)

No, because I wouldn't know how to apply a similar concept to Number items, which could possibly habe ANY value…

Hi,

Some kind of complex item where value comes from one item and icon
comes from another one? :-)
