Here is something else to think about.

Which would you rather do:

1- Open Lighting iOS app and turn off lights, then open HVAC iOS app and set temp for the night to sleep comfortably, then open the iOS apps for every AVR and TV in the house to turn each one off one at a time, then open the iOS app for the security system and set the night/stay mode.

OR

2 - press a button in the Crestron App that says Goodnight.


Anecdote:

Have a client we did a lutron homeworks system for, and another dealer did his AV, just sonos and some URC remotes for TV viewing in a few rooms. He also has a CCTV system, an HVAC system, alarm system.

He uses the dedicated iOS apps for EACH of those systems.

About a month after he moved in and was all settled he asked if I could write a SINGLE iOS app to control EVERYTHING because he was going crazy going back and forth to each app.

I tried to explain a solution exits and its called Crestron/a control system, he never went for it but I believe if he had been presented with the option when the home was built he would be much happier today.
