Hi
This projects comes within the area of my expertise
My approach in solving the problem would be as follows:
Study given documentation. If enough details are available regarding the protocol used for controlling the switches - Develop a new Android App to meet the specifications
If details are not available,
Run your existing App, develop a PC based switch simulator, understand the protocol and develop the App to meet the specifications
I am sure, I'll be able to handle this project to your satisfaction
Thanks
