I want to log all incorrect keypad attempts.  Yes I do have normal
garage door remotes which can bypass the keypad, but I always take my
front door key with me in case of power failure anyway.  Aside from
long-duration power outages, my systems have pretty high availability.

It seems like the keypad might be the limiting factor though.  How
about a UHF remote, has anybody connected one of those to a Linux
system?
