      I have a Neuron with a 1-Wire DS18B20 temp sensor.

      When I look in the /sys/bus/w1/devices folder, I see this:
      0_1489542728673_1Wire_1.JPG

      I am using Node-Red to test and, and this is the error message I get:
      0_1489542758875_1Wire_2.JPG

      What am I missing? As I try different things, the ID in the devices folder changes. I am new to this environment, but not new to development.

      Thanks!

        @SOswald Does it change or does it disappear? Where did you get that sensor?

          It changes. The sensor came from this site.

          Here's what it is now:

            And what's more, there is only one sensor, plugged directly into the Pi, not a hub.

                @SOswald Please check your owfs configuration. You shoudl see only 1 sensor if you have only one connected.

                  @tomas_hora Well, I guess I did have a small typo in my owfs.conf file, but I have fixed that. Here is my current owfs.conf file:
                  0_1490041735702_UniPi_4.JPG

                  All the lines above these are commented out.

                  I still see multiple sensors with invalid IDs, and there are no w1_slave files:
                  0_1490041819222_UniPi_5.JPG

                  Thank you again.

                  Steve
