I just installed the following image: "2016-02-22-raspbian-jessie-lite_vz.img". Then most GPIO's don't work because they are default 0. Only a few GPIO's are default 1 and work with vzlogger (see my previous message for details). The logfile of vzlogger didn't report any problems....
I never found an other image than this one, info about Volkszaehler is hard to find.... Verzonden vanaf mijn Samsung Galaxy-smartphone.
