The value of "the internet of things" lies in its interconnectedness. That is the value of a network grows exponentially with the number of other networks it connects to. If you substitute "networked device" for network and you see the analogy. Home automation systems as I understand them are closed or semi-closed systems akin to the carrier networks of companies like BT. And as they're based on proprietary technology they don't play well together.
Given that the "internet of things" will be driven to be open standards based by the power of the "law" I've tried to describe above controllers for these devices, or clusters of them will also be a device in the internet of things and be capable of controlling them via well defined apis. Having seen what open standards and open source has done for computing, networking and databases I'm excited by what lies ahead in the future. It will be far more powerful, flexible and manageable than the crude proprietary systems that are out there right now. It'll just need time to evolve and mature.
Also, the potential for these types of devices in the future is much more powerful than what probably any of us can imagine right now. I can foresee how these devices might self organize based on loose policies and determine optimal configurations and/or behaviours - kind of like how the nest thermostat learns but distributed learning across the entire house. That kind of technology is some way away I imagine but would take maximum advantage of the distributed architecture of the "internet of things".
BTW, do I spend any time thinking about this? No, because the internet of things is little more than a marketing term right now.
