Thank u,

In your item definition, use [%d %%] as a formatting string, e.g.

Dimmer myDimmer "Volume [%d %%]"

Where is it at this example?
Rollershutter Raffstore { http=">[*:POST:http://hp27/deviceajax.do?cid=9&did=1010042&goto=%2$s&command=0]" }

Try

Rollershutter Raffstore "Text [%d %%]" { http=">[*:POST:[http://hp27/deviceajax.do?cid=9&did=1010042&goto=%2$s&command=0](http://hp27/deviceajax.do?cid=9&did=1010042&goto=%252%24s&command=0)]" }

Also, see here: https://www.openhab.org/docs/configuration/items.html#state
