@bdahlem Just found your comment here: Will the Leviton VRCZ4-M0Z zone controller work with SmartThings?
So clearly you’ve already considered this, sorry! Is there anything I could do to help make this work? I don’t know enough about creating DHs to do this myself, but perhaps (if anyone is willing) I could provide them with logs etc. from my device - I’d love any guidance I can find!
