Sitemap Information of two items in one

Dear Community,

Im searching for a solution to show two item Status in one sitemap item.
In my case Ive displayed the power of my PV battery (first item) and trying to Display the PV battery charge (secound item) in percent behind the text of the label of the first item.
If you have a dimmer or thermostat it is possible to have the Information of the same item.

Is there a way?

Thank you

For sitemaps the only way I know of is to create a third Item that combines the states of the two Items into on Item. Sitemaps are built mostly around a one-item-per-element structure. Other Items can be used to control stuff like visibility and color, but the state of only one Item can be shown per element.

Can you give me an example of combining the two items to one - Im more then happy to try this.
Thank you very much for the quick feedback :slight_smile:

Create a proxy Item and a rule to update that Item’s state when the state of either of the other two Items change.
