iPhone ON and OFF - Open silently web pages to control a relay card -- 2

Hello developers, the iOS app, needs to be native on an iPhone, not a web app. Needs to be compatible with iphone 5 and 6 (also 5s and 6s) The application is very simple, two button ON and OFF. It control a very simple web relays control. To switch on or off the output we need to open a web page. Noting else. The web pages that was opened don't need to be visible to the user. This is the web control: [login to view URL] APPLICATION ON OFF The ON button need to open two web pages: http://192.168.1.X/30000/01 http://192.168.1.X/30000/03 The off need to open also two web pages: http://192.168.1.X/30000/00 http://192.168.1.X/30000/02 Nice to have the possibility to change once at the first time the ip configuration that is the same for all the 4 web pages. Only vertical layout, i prefer that the button is not too big. If there's the possibility i want to add my company logo not too big. Thanks to everyone!
