I have a WM100 at my city place as well as my off grid place for several years I had the app in stalled on my phone with the off grid place configured. On my wife's phone I had the app configured for the city WM100.
I wanted to be able to control both devices from my phone from one location without reconfiguring the app each time.
Today I attempted this again using a couple different cloning apps. Some were so full of advertisements they were impossible to try to even test. I found 2Accounts on Google play and
NO ADDS ( not sure if it is available for Apple devices).
It creates a clone of the app which you can rename, place a short cut on your home screen, and configure to connect to an existing hub.
2Accounts must stay installed on your phone or tablet but you never need to open it again unless you wish to clone another app.
I suspect if you wished more clones of the wifi app you'd need to subscribe.
