Is it possible to change item configuration at runtime

Setup, Configuration and Use Items & Sitemaps
#1

I have an item configuration:
Contact DoorSensor01 “Sensor 01 [MAP(de.map):%s]”

I think the internal item structure files are:
item.name: DoorSensor01
item.typ. Contact
item.label: "Sensor 01"
What internal variabel holds the item label definition “Sensor 01 [MAP(de.map):%s]”?

Is it possible to change this label definition at runtime to:
Contact DoorSensor01 “Monitoring 01 [MAP(de.map):%s]”

I tried:
DoorSensor01.label = “Monitoring 01 [MAP(de.map):%s]”

But this does not work. It changes the interpreted label but not the label definition. Is there a way to access label definition on runtime?

#2

Wait what? Are you trying to change the Label with a rule or why you try to use DoorSensor01.label ?
This would be like this (I think)

DoorSensor01.setLabel("Monitoring 01 [MAP(de.map):%s]")

#3

It looks like .label and .setlabel does the same:

I want to have more information in one line.

normaly:
DoorSensor01.label = “Monitoring 01 [MAP(de.map):%s]”

leads to this in ClassicUI
Monitoring 01 - left aligned
Closed - right aligned

What I want to reach:
Monitoring 01 - left aligned
some text Closed - right aligned
DoorSensor01.setLabel(“Monitoring 01 [Some Text: %s]”)

This is working but if I use mapping part too, it is not working.
DoorSensor01.setLabel(“Monitoring 01 [Some Text: MAP(de.map):%s]”)

#4

I think this is not a problem with the item label manipulation. It looks like the definition of the syntax says:

"No additional text before item definition inside the backets, only behind.

Which means, this will work:
Number DoorSensor13_realrainrate “realrainrate [%.1f mm/h]”

but this not:
Number DoorSensor13_realrainrate “realrainrate [mm/h %.1f]”

Because “mm/h” is the beginning of the part in brackets?
