Smart Lighting for simulated 3 way

I am replacing a 3 way switch for interior lights with a Linear WD500Z and WT00Z. I couldn’t figure out how to associate them, so I’m trying to use the Smart Lighting app to link them. The bscreenshot below shows the configuration I’m using. However, while the switch does turn the lights off, it doesn’t turn them on. Any thoughts?

I think I realized what’s happening. When I use the aux to turn the light off, it’s actually cutting the power to itself. I’ll have to figure out a way to wire it with uninterrupted power. Then the Smart Lighting app should work.
