To clarify - the ePMP SM is only able to function in one of these modes at a time:
Normal ePMP SM connected to ePMP AP
ePMP SM acting as a WiFi hotspot
This means you cannot connect via WiFi to an ePMP SM acting as a WiFi hotspot, and align it as a normal ePMP SM to an ePMP AP at the same time.
There is an alignment app available for ePMP in the iOS App Store - eAlign for ePMP - and an Android version is in development. You will need to connect a WiFi hotspot to the LAN port of the ePMP SM, whilst the SM is in normal ePMP SM mode, to use the app.
