The second note I got from a TB2 user (RPi GPIO module and Pi interface hardware) convinced me to go the the trouble to produce a new version of TB2 just for the addition of 1 small note. There is a single pin on the Raspberry Pi header, GPIO [4], which is capable of being converted to a low speed 1 wire interface.  I personally have never done this but here are a couple of good sites that explain it if you are interested:

and
https://www.raspberrypi-spy.co.uk/2018/02/enable-1-wire-interface-raspberry-pi/

Doing this requires installation of a software overlay but it turns out that this is directly related to a project in my hopper.
