Great system. First time I have used anything like this so it took some experimenting. What I did was put the lock together and get it working manually on my desk. Then I set up the Veralite unit. Put both on my desk so they would pair. Then print the page that has instructions for the Schlage lock. Then on my Samsung S2, download the Vera Mobile android app and install. That will put an icon on your cell. Open it. Select Cameras/Security. Click the lock tab. If your lock is locked, you will see an icon showing an unlocked device. Press it and in a few seconds, your lock will unlock and will stay unlocked. The icon on your cell will show a locked device. Press it and in a few seconds, your lock will lock. First time success. I recommend it. I want to add a camera and some other stuff, but for now this is great. I can give a code to some people doing work on my home before I move in. Or I can simply open the door for them while they are calling. All this for less than $400. I thought that was a lot, but as I use it, it was worth it.
