Seems like u guys are pro in this ht setup. I might be asking in the wrong room, but help me if you can. Planning to move into a new house next year, so wanna buy a ht for the living room.

Budget: rm6k
TV: 55inch minimum, full hd, don't need smart/uhd/curved unless necessary - need recommendation (rm3k)
Sound system: 5.1 setup - need recommendation (rm3k)
Player: currently owns ps3, maybe get ps4 next year. 6k budget doesn't include ps4
Usage: astro hd, dl-ed series/movies in 720-1080p, ps3, music

Question,
1. how to make those integrated system ie; control everything ht, lights,air cond etc through iPhne/ipad?

2. How to setup speakers in diff rooms to play songs from single source eg. Turn on speakers in master bedroom/ study room/ kitchen , to play songs from laptop/PC/iPad/ iPhone. Preferably without wiring. Eg. What I do now is use remote app on my iPhone to control the iTunes on laptop connected to speakers. So I can turn on/off/change songs even when I'm in a diff room. What I want to be able to do is eg. Walk into master bedroom, turn on speaker and play songs from my iPhone. Then later maybe go study room, off the speakers in master and turn on the ones in study room. All controlled by my iPhone. Do-able?

Thank you very much for your kind advices.
