I find it hilarious the guys thinking that the only way to build a system is with an all in one app. There is a big difference between a remote control system to replace multiple remotes on a coffee table and several apps on one phone. Not everyone wants the one app, or they don't want to spend or down have the budget for such a system. To suggest that there is only ONE way to do this job is laughable and I feel sorry for your clients as you are providing what you want and not necessarily what they want.
