Ha! I THOUGHT I had solved it, but it seems like I had a combo of problems. Had to tear out the whole shebang and test systematically. It seems like I didn't READ the SigKSens instructions, but just looked at the pictures for connections. I had connected the 18WS20D (1W) sensors to 5V rather than 3.3V. (as shown on the illustration for SigKSens. While this works for the Arduino, the D1 Mini do not appreciate the extra voltage... So The port was fried on the D1. Changing to pin D6, recompiling, and attaching the old temp sensors seem to work. Will benchtest for a while, then throw it all back into the boat.
