Einbinden der Wetterstation Ventus W830 (Alecto WS-5500) über RFXtrx868

[SpearOfDestiny]

Hallo,

ich habe gestern mein frisch eingetroffenes RFXtrx868XL in Betrieb genommen und musste mit Erschrecken feststellen,
dass das TRX Modul von FHEM meine Wetterstation Ventus W830 nicht korrekt erkennt.

Das Device wird als TRX_UNKNOWN_76 automatisch angelegt.

Ich habe bei RFXCom nach den Dekoderdaten für die Station gefragt, da der RFXManager die Station als Alecto WS-5500 erkennt
und die Readings auch richtig anzeigt.

Besteht die Möglichkeit, diese Dekodierdaten ins TRX - Modul zu integrieren ?

MfG
Marco
