I agree with what has been said, that this is a problem Smart Homes and therefore IoT are suffering from for decades now. For a long time, and still today, most engineers believe the only way to solve the problem is to write a new layer on top of the incompatible protocols / bus systems in order to integrate them. Unfortunately up till today many if not all of these approaches have suffered from the fact, that they usually end up with the smallest common denominator between these subsystem. So the more systems are integrated in a common layer the less functionality will be left that is useful. So by definition you either integrate just a few systems (typically two or three) with a reasonable set of features available or you have a larger number number of subsystems integrated and there is not much more left than turning devices on or off.
There is however a solution that may deal with that problem, which tackles thins from a slightly unusual angle: If you create a surface that shows subsystems in a modular and complete way to the end user and you make it possible to couple those systems you will get a surface that allows to monitor and control a large number of systems on one simple to use surface but you still can provide all the nitty gritty details each if those subsystems allows to do. So combining an infrared controlled TV set with a Philips Hue lamp and a door sensor from let's say Smarthings will become trivial just by arranging their visualization on the same surface. Now add to that the capability to «dock» these control elements to live exchange states and events and you are pretty close to a very practical solution to the problem described. And if you are looking for a system that provides the kind of surface described have a look at dizmo.com
