Red - 3.3 or 5v - constant power
Yellow - Digital - konnected zone of choice
Black - Ground - ground
Resistor needed when using long wires or multiple sensors.
Once wired and configured you will have to wait approx. 3-6mins before the sensor shows up in the things menu with its Id number as its name.
No typo, some people like to use that format where the k takes the place of the .
4k7 = 4.7k, 4700 Ohms
A spec of dirt on a schematic that’s supposed to read 47k gets interpreted as 4.7k could be very problematic
Unsure of the origin of this practice but its considered RKM code.
Hey Brian. Just got mine working this morning. You need a 4.7k resistor between the yellow and red wires on the sensor. Here is an article that talks about that sensor. As soon as I did this it started working in the new smartthings app after a couple of minutes. Good luck. https://learn.adafruit.com/using-ds18b20-temperature-sensor-with-circuitpython/hardware
