Is there a driver or an inlet/sensor that needs to be configured to use the temperature probe? I have it connected to the "Temp 1" port(s) and there's voltage across them that I would expect but Reef-Pi doesn't list the DS18B20 (or any other) sensor. Have I missed a step?

No the temp sensors just show up in the drop down when you add a sensor. Check to see if the 1-wire is enabled on Pi.
In Pi terminal type the following command.
sudo raspi-config
Then go to "interfacing options" and "1-wire" and enable it.

Hi Rob
I'm facing the same issues
Enable it and still, it will not detect anything
pi@raspberrypi:~ $ sudo raspi-config
pi@raspberrypi:~ $ ls /sys/bus/w1/devices/
w1_bus_master1

Hi Fred, the address of the sensor should show up next to w1_bus_master1, the fact you get that means the bus is working.
Can you check the voltage on the port, you should get +5v across that pin and ground and there should be +3.3v across the data pin.
Any chance you have a second sensor to try?

Right on, I guess we know what that means.
