Indigo Touch is our collection of control apps for monitoring and controlling your house. iOS/iPadOS (iPhone and iPad) and web-based clients are available. The clients will communicate with Z-Wave, INSTEON compatible hardware, and device (or other information) supplied by any of our 3rd party plugins.
Indigo Touch provides a broad set of features across the various clients, most of which are provided free. Compare that to many of our competitors who charge for the most basic functionality. We also offer an Indigo Reflector which offers a easy to configure option to remotely access Indigo away from the home. Reflectors are a feature of the Indigo Up-to-Date subscription.
Indigo Touch for iOS/iPadOS also provides some features that are only appropriate for a mobile device app.
Assuming you have Indigo running on your Mac (trial or purchased) and have your iPhone/iPad at home on the same WiFi network, then by tapping the gear icon you can automatically connect to it. If it isn't visible, then check your Indigo server settings:
