Z Wave Lighting

I am looking to have a light that is a 2 way (one is dimmer and one is regular switch) on z wave. I have the linear wd500z-1 wall mount dimmer switch already… what does the other switch need to be?

Thank you

This would be a 3-way configuration. For Linear Z-wave Switches and Dimmers, they create a virtual 3-way switch by using a WT00Z-1 accessory switch which does not directly control the load or physically switch the current, it just wirelessly informs the load bearing switch to turn on or off when pressed.

I also have just one switch that has a dimmer… would the wd500z-1 work on that one?

Yes. You can use the linear dimmer in single switch or 3-way circuits.
