Your sentence is hard to understand.

However, Scriptable widgets can only display information. There are no buttons or similar. You can only view, but not interact with your 3D printer.

That’s unrelated to Home Assistant and Scriptable, it’s a limitation that comes with iOS 15.

Sorry i am very bad at english i just would like to know how to display strings instead of numbers with your code.

You would need to edit Line 203 and 206.
room.temp = Math.round(json[i]['state']);
-->
room.temp = json[i]['state'];

Thank you very much !

How often does it update the values?

I could not find any constant refresh interval, looks like, it is updated on-demand and depends on how often you look at your home screen.

I am having trouble getting the widget to load.

https://community.home-assistant.io/t/ios-widget-for-home-assistant-via-scriptable/284142/33?u=freelanda

How do I add individual text like „km“ or „min“ after each sensor data? I do not want to add „%“ to the whole column.

ext like „km“ or „min“ after each sensor data? I do not want to add „%“ to the whole column.

for example i wanted to return the produce of my solar panels.
let valueLabel = mainStack.addText(${result.value}W);
This is based on the gauge script on this gist.

the "W" is like you want or km or min.

see my full script an example of a forked (edited) version from gauge script m33x
