M100-M199 can easily call a shell script, and a shell script can write

It looks like that Neutral termnal is on the input side of the
transformer.I would NOT connect that to ground as bad things would
likely happen since your input off the phase converter is not balanced

So the input power goes into the H2 terminals. The coolant pump is

Which type of Arduino hardware do you use?
So you get a very high resistance reading from the N to the H
connections with all of the wires off the transformer?
If so, I would ground that N terminal via a fuse (in case you have
