It's possible to control your device over the network using your iPad but you need to download our free Easy Remote app from the App Store. Just make sure the device and iPad are connected on the same network.
It works differently when want to control your device in Stand Alone, you need to build your scene buttons & dimmers etc in the app itself.
Below is a link to the Easy Remote manual which should help.
