Hi, I'm new in the forum. We have a 3-floor building and we are going to use Control4 with a simple EA-1 in each apartment to control lights, AA and shades. Also we are going to put a CA-1 with a DS2 with keypad in the main door. How can we link the 2 nets so we can use de door station from any apartment? even to see it in the TV or cell phones and being capableto unlock de main door.
