 +===== 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.

 +
 +===== Connection check =====
 +  * press the button shortly \\
 +With each press of the button, the relay will
 +switch on/off. Other devices are not affected.
