Notes on Pairing:
Documentation for many Z-Wave devices say that during the pairing process, the two have to be within 3-6 feet of each other. From my personal experience, the first time I paired my Schlage and the A+, they were about 15' from each other with a cabinet between them. I recently had to relocate my cable modem and A+, and now the lock and the A+ are about 25'-30' between first and second floors, and they still pair.
There are some reports that Removing/Unpairing/Excluding the lock as the first step before adding/pairing/including is more successful, but since R065 and factory resets, I haven't had to do this.
Notes on controlling remotely:
The first time I paired the two on pre-R065 firmware, the A+ constantly reported the Schlage as unlocked and no controls were possible.
After updating to R065, both the LCD, Web UI (NutsOS), and connect.securifi.com showed the correct status of the lock and was able to lock/unlock.
At some point, I wanted to factory reset the A+. I unpaired the lock, then reset and set the A+ up again for routing. For some reason, I could pair but not control the lock anymore. After numerous pairing/unpairing attempts, it suddently started working again.
