The generate QR code feature is located on the top ribbon next to the setting button only while you are on an individual socket view. Each QR code is unique to the socket.
Clicking the generate QR code button will download an image of a QR code. This can then be used digitally, or printed and used to access the control functions of the socket.
Scanning the QR code brings you to the control page for the socket
The digital buttons on the socket can then be pressed to turn on/off each side of the socket.
If a socket is set to be off, the override will last for 2 hours before reverting back to the energy-saving state.
NOTE: Users must have control permissions to be able to turn on/off sockets.
