* turn on all devices as the same time
* within 10 seconds, while RF LED is blinking, press and hold button on one of the devices
* after a second, the new address is randomly generated and sent to all devices. RF LED will blink 3 times to confirm the new address.

* turn on the device
* within 10 seconds, press and hold button on one of the existing devices
* after a second, the existing group address is sent to the new device. RF LED will blink 3 times to confirm the address is sent.
