Low voltage switch

I need a z wave enabled low voltage switch. I basically need a device that on a ‘close/on’ command from Vera closes a contact and on ‘open/off’ command opens it.

Does anybody have a suggestion?

the only one I am aware of is the ZRF-113, runs on 120V, but has an isolated contact closure you could use for low voltage.

I’m using these on low voltage landscape light works great.
