The Android app gives you access only if one applies a separate account from the manufacturer !? You can not assign a DDNS NAT addresses manually but must specify the app's account from the manufacturer. This means the power strip is talking to the manufacturers !?

I am surprised that in this day and age such a thing is still on the market ... just looking for alternatives ...
