Its very simple if you know what to do.
You have 3 construction sites:
1: bring Asiair in your Local Web to work
2: Get a VPN Connection from where you want to be to the network with the Afiair
3: bring Bluestacks (or whatever emulator) to work and connect to the Asiair.
I did it with my stuff. I use a VPN Connection with my cellphone to my home network.
As that worked and i am a part of the network i can ping every device.
Thats the big thing.
Ib my router (Fritzbox) i managed to get the Asiair to get the same IP - thats is for me important! As my cellphone gets a Full iP Check from 0.0.0.0 to ... whatecer my cellphone never find my devices automaticly but they are ping-able.
So - when connectet over vpn to the network i can in the Asiair app instead of a search write the IP Adress and that works!
In your Emulator you have to activate a Network bridge so you can search in the Network!
In my case bluestacks never worked and i use Moavi, or somewhat. But same story. Install the .apk and than manage to integrate that App in the notwork. Bride mode.
Be sure to work step by step and get sure everything work as planed when you build that thing up as there are so many chances to fail and you need a structure what work and where a possible fault is.
Good luck - have fun
