I have a question about the dsm node. I am looking at the hysteresis example on the wiki [1] and I want to change it so that it only sends a message on the way down and does nothing on the way up.
I tried
"cross_high": [
"msg = null;",
"sm.fill = 'green';"
],
but then it just passed on the original message.
