I'm having trouble connecting to multiple exterior door locks. Was disappointed that my Vera controller couldn't get through. I was also hoping that my wired light switches would work as a repeater, but I was still having connectivity issues. These extensions connected to my Vera controller in 30 seconds and every device on my network started working within 5 minutes of finding these two extensions in my house. They're working great so far. Very easy installation. Buy them with your controller as the Z-wave signals are not very strong.
