Wire 3 Way Switch with Monoprice Dual Relay module

Does anyone have a wiring diagram for how to use this device with a three way switch. I have both a constant hot and a neutral available in the box.

Did you ever manage to figure this out? I’m looking to use my existing 3-way wiring with one of these too?

Im planning to do the same thing. I have a 4 way circuit. Most likely u need to add it to the last switch in the circuit , the one that goes to the load.
