How is the Honeywell Vista Automation Module different from the Honeywell Tuxedo Keypad?
The VAM is different than the Tuxedo Touchscreen Keypad because it's not a keypad. All the VAM really is is a Z-Wave Home Automation control that wires into the Honeywell Vista systems. You will access the VAM by connecting it to your local area internet network.
Upon accessing the VAM on the local network you will get a nice interface where you can learn your Z-Wave devices and set scenes for them to act when certain conditions are met. Scenes would be comparable to an instance where your alarm system gets tripped; you could program a scene to make your outside Z-Wave lighting flash.
