Hello,

I have a FMB130 connected with 1-wire a sensor DS18B20 according to this diagram, when the installation is finished all are working and record the temperature, but when the car is turned off (ign = off) the tracker report a lost comunnication on the sensor (io72 =3000) .

An alternative I was trying to put a resistance of 4.7K ohm but is the same situation
