extending z wave over wire

I have a workshop that is about 10 feet out of reliable range from what I can tell. (I used a lamp module on an extension cord in the middle of the yard to get reliable communications.) I have four conductors going to the shop all the way back to the vera that I can use. Is there a way to extend the z wave to the shop using the wire so it will be rock solid? Does arduino make something? It is about 100 feet.

Thanks, Victor.

No, there is no method of extending Z-Wave, a wireless protocol, over a wire.

Vera has a systems called bridging that connects two or more Veras, and their discreet Z-Wave networks, over TCP/IP . These bridged units can then be managed as a single system. However, I suspect that this (two Veras) would likely be overkill for your application.

You midway lamp module sounds like you best bet. I presume/hope that it is in an adequately weatherproof enclosure.
