depends on what you want to do. The devices I've seen are zwave. One way control shouldn't be too hard with RTI connected to an RZCOP. The last time I looked into it, the device is normally locked...and can be momentarily unlocked via zwave to get in....would think it would be pretty simple to then unlock the front door from a remote or in-wall.

Now...having it send you an email when the door is unlocked from the outside like control 4 can do...is going to take a little more than just a driver.
