Switches When the switch is paired with at least one controller, its LED indicator flashes when the switch is pressed. The flashing LED indicates that the switch has successfully communicated with its controllers. Controllers The LED on the controllers indicate several states: 1. Solid green means the controller connected to power. 2. Solid red means the controller is activated. 3. Flashing green means the controller is waiting for a switch pairing or controller grouping. 4. Flashing red/green means the controller has received the pairing/grouping command and is waiting for a command to lock in the grouping/pairing. 5. Rapid green flashing followed by solid green means the controller has successfully locked in the pairing/grouping.
