Thanks. A few more parts on order and if I can figure out how to wire up a master power button without screwing the pooch I'll be good to go.

http://blueacro.com/controllers/picobetaWhere did you get the reef-pi pico board?
Red VCC
Yellow data
Black gnd
Based on this from the build guide I think it's right:
Assuming the tip of the male audio jack is upward, the longest terminal of the jack represents GND, left terminal represents +Ve and the right terminal represents data.
Did you see my followup re: series v parallel?
I attached a photo of the physical wiring of the 2 sensors to the protoboard as well, above.

Missed the follow-up. The pinout looks correct though.

@theatrus I rewired so that they aren't in series. I now see 3.3v when probing each VCC/gnd.
But the sensors still aren't showing up in ReefPi. I've double checked the wiring on the sensor side. Still no joy...
Should both sensors be connected to the same data line going to the TRS connector? I have both data lines and the TRS data line in the same 'row' on the protoboard.
Yes, they share the same data line. Does using one sensor alone work? Can you confirm that you have enabled 1-wire in the /boot/config.txt file (using the pico board example has the 1wire support turned on)?
