These two three way switches control a series of top outlets.
I connected the Zooz s2 zen 26 up as best I could figure and the lights connected to the outlets are flashing.
I connected the red (common on the dumb switch) to Line
I connected neutral to the bank of white wires in the box (maybe this isn’t neutral?)
and the remaining black and white to load and traveler (tried both combos)
I’ve worked with three way wiring a decent amount, but this seems odd.
