I am taking my first steps toward automation. I just bought a home with an alarm.com system installed. Right now its only setup to control the door lock and the thermostat. I want to look into lighting automation solutions. If I buy the Lutron controls, do I need to also buy the hub or is that built into the alarm.com system. My alarm.com system has the "emPower" tab and it says "Your service plan includes Light Automation, but it doesn't look like you have any light devices. Please contact us for assistance."
