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.
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.
