techem compact v - nanocul - crc fehler
« am: 06 Januar 2018, 10:07:24 »
hallo,

ich versuche mein wärmezähler mit dem modul https://fhem.de/commandref_DE.html#TechemWZ auszulesen. als hardware nutze ich dafür ein
"nanoCUL USB Stick FTDI CC1101 868MHz".

auf dem stick wurde die aktuelle firmware culfw-1.67 gespielt. die board.h hab ich angepasst:
* HAS_MBUS aktiviert
* ein paar protokolle die ich nicht benötige deaktiviert (damit keine ram probleme auftreten siehe https://forum.fhem.de/index.php?topic=72682.0)

jetzt meine frage was genau funktioniert hier nicht? das "TechemWZ" lief die ganze nacht im "listen"-mode, ohne ergebnis. ich geh aktuell davon aus, dass es mit dem crc fehler zu tun hat.

Antw:techem compact v - nanocul - crc fehler
« Antwort #1 am: 07 Januar 2018, 17:09:12 »
nach langem suchen im forum hab ich die excel tabelle von bolligru gefunden (https://forum.fhem.de/index.php/topic,42232.msg388780.html#msg388780 und https://forum.fhem.de/index.php?action=dlattach;topic=42232.0;attach=44097) gefunden die wurde für den techem compact v erstellt. wenn ich die rohdaten des cul dort eintrage kommen sinnvolle werte raus. stichtag, verbrauch, ablesetag passt alles.  ;D bis auf den crc. jetzt schaue ich mir mal an welche crc werte nicht passen.
