Control4 is a expensive system when you control and entire home. It does a great job of that. However, each time there is an app update certain parts of the app dont work. For an example; we use Slacker Radio to stream music-since the update the Slacker streaming function doesnt work. There are always bugs after a release. I except more from Control4! Update: taking another star away. You can no longer view cameras that are part of your system. This app is the worst. Control4, pls hire an app developer! In addition, if you are a Spotify use you will not be able to connect to your account through this app. Worthless!
