[SOLVED]
After some procrastination, I decided to tear it all down and take the ESP and a couple of sensors home to see if I could understand what went wrong. Turned out ONE of the sensors had died, thereby compromising the entire bus, which gave no signals from the rest of the sensors. SO - if you get "-" or value "null" from your 1W sensors, only one of them might be the bad guy. I had 7 sensors on my D1 Mini. So far I have re attached 3 and they all seem to be running. One question though - is there a better way to connect the 1W sensors than a star?
