If you haven't already you will need to download and install the WIFIPLUG app from the Apple App Store and login with your WIFIPLUG account. For help with this process please refer to this guide and then return here to continue setting up your WIFIPLUG.
Plug your WIFIPLUG into any mains socket within range of your router and activate pairing mode by pressing and holding the button on the front of the plug for 10 seconds. Pairing mode is activated when the blue light is visible and rapidly flashing.
Open the WIFIPLUG app and login to your WIFIPLUG account. Head to the 'Devices' page (navigation drawer > Devices) and press the add icon in the top right corner.
A prompt will appear asking if you are setting up a HomeKit enabled device. Press 'No'.
Your plug should already be in pairing mode. Press 'Next step'.
Leave the WIFIPLUG app and open Settings (keep WIFIPLUG open in the background). Go to your connection settings via Wi-Fi and connect to "PTS-WiFi" or "wifino1". When connected, return to the WIFIPLUG app and press 'Next step'.
Enter your WiFi credentials. Your network name (SSID) should have been filled in automatically but you can change it if you wish. Optional: check 'Remember WiFi password' and the app will save your WiFi password to make setup for future devices easier.
Press 'Begin setup' and the app will begin setting up your device. Please keep an eye on this screen as you may be given further instructions.
Your WIFIPLUG is now ready for use.
