      Very strange. Are you using the same OneWire library in both cases?

            No, must be hundreds of users running Dallas sensors here. Trying to figure out if anything has changed in the library/dependencies but I don't see anything except the thing I mentioned earlier here.

            And you can get the sensor running without MySensors library loaded...

            Guess I have to hook up a Dallas sensor myself to check (tomorrow or so..)

              Are you powering your Dallas sensor using the 'one-wire' method? Is your arduino 5V or 3.3V?

                exactly like o the example so power from arduino 5V (not parasite)

                  Can you post the serial monitor logs, from both gateway and node?

                    @rvendrame, why You need log from gateway? When no values are sent from node than nothing on Vera. When use some dummy values which are visible in node log - than those values are in Vera.

                      Ok, tried latest from 1.5 branch and it works fine here with 2 hooked up DS18D20.

                      sensor started, id=200, parent=0, distance=1
                      send: 200-200-0-0 s=255,c=3,t=11,pt=0,l=18,sg=0,st=ok:Temperature Sensor
                      send: 200-200-0-0 s=255,c=3,t=12,pt=0,l=3,sg=0,st=ok:1.1
                      send: 200-200-0-0 s=0,c=0,t=6,pt=0,l=0,sg=0,st=ok:
                      send: 200-200-0-0 s=1,c=0,t=6,pt=0,l=0,sg=0,st=ok:
                      send: 200-200-0-0 s=0,c=1,t=0,pt=7,l=5,sg=0,st=ok:27.9
                      send: 200-200-0-0 s=1,c=1,t=0,pt=7,l=5,sg=0,st=ok:28.0
                      send: 200-200-0-0 s=0,c=1,t=0,pt=7,l=5,sg=0,st=ok:31.5
                      send: 200-200-0-0 s=1,c=1,t=0,pt=7,l=5,sg=0,st=ok:32.0

                        removed all Arduino related stuff from PC
                        Installed new IDE and libs from https://github.com/mysensors/Arduino/archive/master.zip
                        now I have progress, there are no readings no mater on which sketch hahaha.

                          Hi,

                          I have the same problem. No temperature is transported to GW.
                          This log is from Sensor:
                          req id
                          send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
                          sensor started, id=255, parent=0, distance=1
                          req id
                          send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
                          req id
                          send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
                          req id
                          send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:

                          I have added some exstra lines in serial printout so I know that ds1820 is found and read.

                          req id
                          send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
                          sensor started, id=255, parent=0, distance=1
                          req id
                          send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
                          req id
                          send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
                          **Sensors found
                          1
                          **req id
                          send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
                          temp :
                          23.80

                          But This value is not transported to GW.
                          Any idee ?

                          Thanx
