The Smart Plug may be paired either from the MiHome app on your smart device (Android or Apple IOS) or from a web browser connected to the mihome4u.co.uk server. See also the MiHome Gateway user guide.
Pairing Via a Browser:
Hold down the button on the front of the unit for 6-8 seconds. You should see the red light on the unit start flashing at 1 second intervals.
On the webpage choose Manage Devices, then Pair Device and select the Smart Plug followed by Register Device. If pairing is successful, the red light on the Smart Plug should then briefly flash rapidly for a second. You will then be asked to confirm that the pairing was successful or cancel if you did not see the light on the Smart Plug flashing quickly. Once you have confirmed pairing, you should see the device come up on the screen as being paired.
Pairing via the App on your smartphone:
Similarly follow the instructions in the App to select and pair a Smart Plug. You can then view and control your paired device by selecting the Dashboard option on your App or in your browser.
