Hi @Twanislas thanks for this, but we do our translation management in Lokalise. Please see https://developers.home-assistant.io/docs/en/internationalization_translation.html

Oh !

Sorry for the spam then, I'll head over there ;)

Thanks !

[bramkragten]

No problem!

Sorry for the noise again but I fail to understand how to add new keys for translation in Lokalise.
Should those be added first somewhere and it will reflect in Lokalise to be available for transalation ?

Thanks !

[bramkragten]

Yes, you can't add new keys in Lokalise, that should be done in /src/translations/en.json that will be uploaded to Lokalise when we push to master.

Gotcha ! Thanks again !

Opened #4128 ;)
