Streamlining Smart Home Communication – RTInsights
Manufacturers need to develop smart home products built upon a foundation of genuine intelligence and independence. Distributed intelligence imbues devices with these qualities almost by design, helping developers to accelerate the journey into an exciting new era.
Intelligent, responsive homes are becoming indispensable to domestic life, with the number of connected devices multiplying rapidly to 1.3 billion projected subscriptions by 2023. So, it’s important to consider how all of these devices in a smart home operate and work together.
There are three models. The first, the common (not so) smart home model that we are currently used to, is built on the shoulders of devices that outsource all of their intelligence to elsewhere. Each individual device – even the ‘hub’ devices like smart speakers – have very limited intelligence ‘built-in.’ Instead, they all rely on communicating directly with their own cloud networks in order to perform any of the ‘smart’ tasks we demand.
The second model still features ‘dumb’ devices but creates a smarter, more robust home environment. Rather than have each device rely on a spectrum of cloud environments outside the home, this model focuses on a central hub that locally manages interactions with devices installed around the home. That hub then handles all of the interaction with a more limited set of service providers in the cloud, significantly reducing cloud communication, privacy issues, and points of failure.
The third, the zenith of the smart home, would imbue each individual device with the ability to communicate with its peers and think for itself. If we put the smarts in the sensors themselves and create a network of devices that can communicate directly with each other, we remove the necessity for data to be transmitted outside of the home. The central hub won’t be needed here, which means easier installation and possibly faster decision making.

Getting our wires crossed
To illustrate the point, let’s say you’re winding down at the end of the day. It’s time for lights out, and you say, “Hey Google, goodnight!”
In the basic smart home architecture, my Google Home will use its broadband connection to transmit this command to the cloud for interpretation. It will then beam the resulting actions across the world to my smart plug providers in China. This provider will then communicate with the home’s plugs. Every device in this chain is reliant upon the cloud to perform.
This model is inefficient by definition. Each of these devices is working in isolation, requiring interaction with its vendor’s private cloud service just to function individually. Each communication they require is a potential point of failure for your instruction and, in a worst-case scenario, a potential attack surface for a hacker, whether they intend to steal your data or simply to deny service.
There’s also the obvious problem of energy consumption. Each transmission burns energy, as do the lights that you accidentally leave on when those transmissions fail to connect. It’s this sort of incremental increase that sees unused smart items in the home consuming significant energy, even when inactive.
All of these problems are part of the same theme: inefficiency. The ‘not-so-smart’ model for the smart home paradoxically relies entirely on an awkward and unscalable global network of communications. An architecture that is more a reflection of smart home device vendors’ ambition to capture our …….
