I have an 1wire Pi (2014 version) and recently i have changed my PI model B to Pi model B+ with 1Gb.
I don't know if there is a relation, but after rebuilding all the domoticz server, with owfs installed with apt on raspbian,(/usr/lib/owfs/owfs version: 3.1p5, libow version: 3.1p5)
i have erratics readings : sometimes 12 family components are read, sometimes not (DS2406 dual addressable switch).
More, 28 family (DS18B20 temperature sensor ) are nearly always presents.
