If you would like to translate to the MijiaTemp app for your language you can clone this repository or download the necessary XMLs (eg. the default English) and translate them (from values and values-v23 directory). The right way if you create directories (values-<lang>, values-<lang>-v23) for the translated language eg. values-hu and values-hu-v23 for Hungarian, values-de and values-de-v23 for German, etc. The correct language codes are in ISO639-1 colum at this link.
At the end you can init a merge in github or it's enough if you send the XMLs files to me to smrtprjcts+mijiabt at gmail dot com.
Thanks
