I am still dealing with signal issues, due to the layout of the building I'm in and it being a metal building. It is basically two metal building joined together by a metal tunnel. At night, the tunnel is closed off with a 10x20 metal overhead door. Thus, creating a more difficult path for Z-Wave signals.
I realized that I needed to reposition my vera to a location closer to the tunnel, and height would increase the reliability of the network. (other side of the tunnel is a Kwikset Zwave lock that is VERY stingy with what it will respond to.)
Therefore, I am remote mounting my VeraLite with a single CAT-5 carrying data and power, by using a Passive PoE Injector/Splitter set.
I found the Huacam HCP05 Passive PoE Injector/Splitter DC Connector on Amazon, as of this writing (August 2014) it is priced just under $7. This set includes the power connectors pre-installed, so it is a quick "plug&play" install with the Veralite's factory power supply.
So far, I have only used this with a 10ft piece of Cat5. Voltage drop can be an issue on longer runs, so it may require more voltage at the insertion point to compensate for voltage drop.
