Before pairing, connect the plug to an electric socket, download the Tydom app and launch it. Go to the « Settings » page of your installation, select « Add a device », « Plug », « Smart plug – Delta Dore », press the button for 3 seconds. Make sure the blue LED is flashing quickly then tap “Associate”. As soon as the plug is associated, it stops flashing. If it is the first installation, it is necessary to create a Zigbee network during the association process.
