I had asked for this early on and as I add more and more devices to the WM100 it becomes more and more relevant.
The last app/firmware update required me to factory restore both the app and WM100 luckily this was my off grid WM100 so I only had about 10 devices on it.
the last time I asked some users to test a pre release few would due to this fact.
No one wants to have to reenter their entire setup after a app or firmware update!
