Weewx, raspberry pi, davis vantage pro2 - problem

[yacenty]

Witajcie,
moja druga stacja meteo, tak więc zerowe pojęcie już mam.
Na pierwszej mam weewx, raspbery pi (1b), wh2080 - wszystko działa jak trzeba.

Od dziś walczę z drugim zestawem
weewx (3.5.01), raspberry pi (2b), davis vantage pro2, davis dataloger usb.

i niestety nie mogę się połączyć
nie ma odczytów w logach,
przy próbie wee_device --info dostaję:

o co chodzi?
Jak to diagnozować?

ciekawostka - raz na 5 odpytań wee_device pokazuje dane
czyżby niestabilne połączenie usb?

[miniomax]

Jaki masz zasilacz do RPi?? jaki masz prąd wyjściowy. Plus podaj jeszcze stronkę na którą wysyłasz dane albo na samym RPi :d

[miniomax]

http://www.blueskybust.com/homewx.html tutaj masz instrukcje jak ktoś instalował. Podałeś dobry port wejściowy od Davisa?

[yacenty]

jak port był zły to nie szło nic, teraz po prostu jakiś duży random idzie.
ładowarka - zwykła od pierwszej z brzegu komórki - dodam od razu do raspberry na usb podpięty jest davis przez ich logger i karta sieciowa wifi.
