My head is spinning trying to figure out what to do with home automation. Connected to a smart home system we'd want ... an alarm system, internal intercom, video doorbell, some lighting, some electronic shades, speakers (don't need a fancy sound system) and HVAC. I am looking at Control4, Vivint and ADT Pulse. Would love to learn from others about their experiences with any of these companies. Obviously it would be nice to have as much on one system as possible, but i'm wondering whether its worth the potentially higher price tag of Control4.
