I would like to connect an iDevices WIFI wall switch to an end of line single pole connection which controls the my table lamp connected to an upper wall outlet. The wifi switch has a red, black white and ground. My wall switch has a black, white and ground. The white is the load (hot wire) coming into the switch.
I know there's a way to do this but I can't seem to find a diagram on line.
My question is in the title: How do I connect a WiFi enabled wall switch?

The problem you have is that your current switch is wired as a switch loop. This means that a hot lead comes into the switch box and a switched hot lead leaves the box. There is no neutral wire in a true switch loop. Commonly a white wire is used for the line to the switch, but it is supposed to be marked with black tape or a marker to indicate it is hot.
While these are common in older circuits, current practice also requires a neutral wire to be present in most switches. And your new wifi switch needs a neutral. Unless there are other wires in the switch box, this switch cannot be used without additional new wiring.
