Is it possible to control a Zwave lock from a zwave light switch. I am trying to control a downstairs door lock by installing a zwave lock and using an upstairs light to show lock status and also be able to lock unlock from a light switch. Also I would like to control the lock from a phone intercom that puts out a momentary close when the * key is pressed. This would work if I could use an ICM from PulsWorx although PulseWork is not Z-Wave compatable.
