-===== Radio pairing configuration =====
-==== Create new secure group ====
-  * 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.
-{{ wiki:20_rdc_charger:03_hardware:wm1_configuration_1.png?nolink&0x500  }}
-==== Add new device to the group ====
-  * 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.

-==== Examples ====
-{{ wiki:20_rdc_charger:03_hardware:wr-1_examples.png?nolink&0x300  }}
-===== Connection check =====
-  * press the button shortly \\
-With each press of the button, the relay will
-switch on/off. Other devices are not affected.

-===== Factory reset =====
-  * Hold button and turn the device ON
-  * RF led will blink twice. Group address is now reset to default.
-  * Other devices will not be affected.
