How can one single BT remote be used to control multiple receivers or switch among them? Will this be possible in the app?
You can link up to 5 devices (Smart Hubs or Smart Controllers) together.
To create a network you first need to connect a Samrt Hub and a Smart Controller.
First Hub connection
Turn Hub and Controller ON by pressing their green buttons and they will link. The LED will blink white and then shift to same channel color e.g. blue. You can now change the channel color by pressing the green button on the hub and toggle through the 5 channel colors. When turning OFF the Hub or Controller the last connection is remembered and re-established when turning both ON.
Adding Hub to network
With the first Hub and the Controller ON and connected you can add extra Hubs to the network by turning the new Hub ON and then press both green buttons simultaneously on the new Hub and one of the components in the network (Hub or Controller). The new Hub is now added to the network with the same channel color as the currently selected channel. Again toggle to another channel by pressing the green button on the Hub. When more Hubs on different channels are added to the network you toggle between the different channels by pressing the green button on the Controller.
