A few years back I looked into getting CE certification for a media-player hardware project, and the funny thing was that in Germany there is no place to apply for it. TüV can test it for you if you want them to - and you might get a nice certificate to hang up on the wall, but that doesn't mean that someone will be stopped from suing you if the device causes interference or eats their socks. I talked to a lawyer and a business owner in the industry of producing hardware, and what they told me was easily confirmed by more than just [[ https://de.wikipedia.org/wiki/CE-Kennzeichnung | wikipedia ]]:
```
Die CE-Kennzeichnung ist daher kein Qualitätssiegel,
sondern eine Kennzeichnung, die durch den Inverkehrbringer
in eigenem Ermessen aufzubringen ist und mittels der er zum
Ausdruck bringt, dass er die besonderen Anforderungen an
das von ihm vertriebene Produkt kennt und dass selbiges
diesen entspricht.[1]
```

So congratulations.
