even REST style of communication is not efficient and good enough.
So they have internally started implementing more optimized style of communication
that is more efficient on network traffic,
and more efficient on server side processing.
(and wait for responses) that is very dependent on specifics of
more than 800 types of supported devices.
The solution are custom, more high-level messages,
that are implemented for and by client team and running on severs
to prepare complete data and return in one optimized message.
without creating too much additional load on servers.
For this they have implemented "Reactive Functional Programming",
that is first introduced by Microsoft Research's Eric Meyer as RX Framework
and added to .NET and other tools.
Netflix has adopted same style, and implemented for Java platform
but not Java language: instead they are using Grails in JavaVM.

All we need now is a clever catchy name for the new style protocols,
and a simplified portable open source implementation, i.e. for Node.js :)
If that can be a part of some PhD thesis (like REST was), even better :)
Would "web sockets" and "comet-style" connections be effective here?
