Hi all,  
I’m on the way to migrate my OH-Rules to Python/Jython. Now I have a little problem with the following command-line in my script:

```auto
ir.getItem("localDayTempForecast_{}".format(day_count)).setLabel(u"Temperatur-Aussicht:({:>10}): [%s]".format(DateTime.now().plusDays(day_count).toString("EE, d.MMM")))

```

The command changes the Label of an item, but there is no refresh in the sitemap only if I made it manually via browser.

.items is:

```csv
// ++++++++++++++++++ Concatenation for sitemap presentation +++++++++++++++++++++++++++++++++++++++++++++++
String localDayTempForecast_0 "Vorschau Temp. [%s °C]" <forecast> (gOWM1,gAVGTemp) // Value calculated via Rule
String localDayTempForecast_1 "Vorschau Temp. [%s °C]" <forecast> (gOWM1,gAVGTemp) // Value calculated via Rule
String localDayTempForecast_2 "Vorschau Temp. [%s °C]" <forecast> (gOWM1,gAVGTemp) // Value calculated via Rule
String localDayTempForecast_3 "Vorschau Temp. [%s °C]" <forecast> (gOWM1,gAVGTemp) // Value calculated via Rule
String localDayTempForecast_4 "Vorschau Temp. [%s °C]" <forecast> (gOWM1,gAVGTemp) // Value calculated via Rule
String localDayTempForecast_5 "Vorschau Temp. [%s °C]" <forecast> (gOWM1,gAVGTemp) // Value calculated via Rule

```

.py is:

```csv

When the script is triggered sitemap shows:

When making a manual refresh of the sitemap, I get:

Any hints for me ? I am grateful for all the answers.

thx in advance

It’s an undocumented function, the UIs don’t listen for label changes.

Thx for reply.  
I don’t know if it’s undocumented, as I found information about it [here](https://community.openhab.org/t/experimental-next-gen-rules-engine-documentation-4-of-writing-scripts/55963) and [here](https://community.openhab.org/t/solved-using-item-label-in-timer-routine/86015/3) and of course [here](https://openhab-scripters.github.io/openhab-helper-libraries/search.html?q=setlabel&check_keywords=yes&area=default).  
As I’m trying to learn Python/Jython/jsr223 and trying to migrate my DSL-Rules to Python-Scripts, I looked here and there and found the above sources.  
As said I’m running OH with NGRE/JSR223 on my testmachine, where also the original “owm-script” of Scott is running, which has a lot of such features, and which is the base for my learnings.  
Maybe OH3 will understand the code???!! 😉

There’s no problem with the code. The code is doing as expected, changing the Item label text.  
Your problem is the UI doesn’t know or care that it changed.

I don’t expect it’ll be any different in OH3, it might.  
In order for this to work as you wish, several things would have to happen -  
openHAB core would have to create a new event signalling Item label change.  
Every UI would have to be modified to listen out for the new events and update display.

thx again.  
It’s a pity. But then one can’t do anything. I thought so. Even if I first made the change of the label and then update the item’s value.  
So I have to think about to do it like Scott does in his owm.py script. Where he removes and recreates those items “on the fly” and not using items of a textual configuration. But at the moment this is too big stuff for me.  
It’s always a pleasure for me to discuss with you and getting a helping hand, as in my former “owm.rules” if you remember. 😉
