Change UI Language does not work

I would like OH UI all in Englis, I ran OH 3.4.1
I setup Language to English:

But in some place, all is still translated to italian, here is when I create a rule:

Translation in italian is very good, but I prefer to have all in english


Did you setup the computer to use italian language? Would be

sudo dpkg-reconfigure locales

and select en_US.UTF-8 UTF-8, then select en_US.UTF-8 as the default for system.
After confirmation with ok, do a complete reboot (easiest way to get all software using the new locales)

Hi @Udo_Hartmann
I run OH in a docker container. It is possible to do that without reconfigure locale on host?


Ah, docker :slight_smile: Please check the yaml code (if started through docker-compose) or the docker run command.
You’ll have to add the environment variable


See Docker for details

here is ENV variable on my docker container:

it seems is just set as you suggest

Hmm… Then I have no idea…

The language is selected based on the browser’s Accept-Language header, which is most likely the same as the language of the device you’re using, unless you manually reconfigure that.


Cool. Haven’t know that before that it is done in that way for a subset of the menus/text in OH.
I also had a mixture of English and local language. The later changed when I set my browser’s language priority to english as well.

And how can I have OH all in english, without changing the language of my PC/Browser?


Depending on your browser, there might be a setting for language priority. This will affect other websites as well however, if they use the header to select language.

Which browser do you use ? For firefox there is an extension that should be configurable per website: Accept-Language per site – Get this Extension for 🦊 Firefox (en-US)

I will look for Chrome


I just reboot for another reason, and found in OH logs:

2023-02-08 21:26:33.281	INFO 	.core.internal.i18n.I18nProviderImpl	Locale set to 'en_IT'.

Why en_IT ?


en is the language setting, while IT is the regional setting, affecting e.g. date formats etc.

This is the guy for Chrome:
