Tomorrow’s smart home: a small autonomous data center?

The first generation of home automation mainly taught us how to connect objects. A switch could be controlled remotely, a thermostat programmed from an app, a camera viewed on a phone, and a voice assistant could turn on a light. Each new device generally brought its own app, its own user account, its own cloud service, and its own little technological universe.

That vision is starting to show its age. Connected objects keep multiplying, but the most interesting transformation is now taking place in the way they communicate, process their data, make certain decisions, and collaborate with the other systems around them.

Progress in standards such as Matter and Thread, the rise of local control platforms, the growth in computing power available at the network edge, and the gradual arrival of artificial intelligence in these environments make it possible to imagine a home very different from the one we call “smart” today.

It could progressively become a genuine domestic computing system, distributed across dozens or possibly hundreds of devices, capable of processing a significant share of its data locally, coordinating its resources, and using the cloud when it delivers particular value rather than depending on it for every one of its functions.

Tomorrow’s smart home could thus offer a surprisingly concrete preview of the future of the Internet of Things: billions of machines with identities, capabilities, and varying levels of autonomy that will have to learn to work together.

Interoperability is one of the first conditions of this evolution. Matter, launched in 2022, continues to develop by progressively broadening the categories of devices and the functions able to use a common language. With Matter 1.5, the standard notably supports new device categories as well as advanced functions related to energy management.

This evolution may seem highly technical, but it sets the stage for a fundamental change. When devices use more common standards, the home can progressively stop being a juxtaposition of independent products and become a genuine infrastructure.

Thread contributes to this transformation with a low-power IPv6 mesh network particularly well suited to sensors and small battery-operated devices. Matter can run on top of Thread, Wi-Fi, or Ethernet so that different devices can communicate through common mechanisms.

This standardization will obviously not make all devices identical, nor will it instantly eliminate proprietary ecosystems. It does, however, create an essential condition for distributed intelligence: to coordinate several devices, they first have to be able to exchange enough information to understand what is happening around them.

A second transformation could have even more significant consequences: the return of part of the computing workload to inside the home.

The cloud has contributed enormously to the development of connected objects. It has allowed manufacturers to quickly provide storage, analytics, updates, specialized services, and remote access. This architecture has also created dependencies. An Internet outage, the discontinuation of a service, or the disappearance of a supplier can sometimes considerably reduce the functions of a device that is nonetheless still physically present in the home.

Local architectures offer another way of distributing intelligence. Home Assistant, for example, can run on hardware installed directly in the home and keep a significant share of its data local. When the devices allow it, their communications can also stay inside the home network. Matter itself provides for local control of devices for certain functions without requiring every interaction to pass through a cloud service.

This architecture becomes far more interesting when we consider the computing power now available in small devices. A home controller no longer necessarily has to be limited to simple rules such as turning on a light at a set time. It can analyze different data, recognize situations, perform certain inferences, and begin to run artificial intelligence models locally.

Even voice interaction is heading in this direction. Some platforms already make it possible to run recognition and control functions locally while retaining the option of calling on more powerful external models when doing so delivers sufficient value.

This evolution profoundly changes how we conceive of the smart home: part of its intelligence can now stay at home.

The shift from local control to local intelligence then opens the door to another transformation. Traditional home automation works essentially on commands and rules. A new generation of systems could work more according to context and to the objectives set by the occupants.

A home equipped with sensors can already know the temperature, the humidity, the air quality, the light level, room occupancy, the state of doors and windows, and electricity consumption. With other equipment, it can also know solar production, the charge level of a home battery, the availability of an electric vehicle, and various pieces of information about the energy grid.

Matter is in fact beginning to standardize certain interactions related to generation, consumption, electricity rates, and vehicle charging. This structured flow of information makes it possible to envisage systems capable of optimizing several resources at once.

The thermostat provides a simple example. Instead of asking it solely to maintain a temperature of 21 degrees, the occupants could define a broader objective: maintain a given level of comfort while reducing the energy cost. The system could then take into account the weather, the occupants’ habits, the price of electricity, solar production, the state of the home battery, and the expected time of the next trip in the electric vehicle. The home would no longer simply follow a program. It would continuously adjust its operation according to objectives and constraints set by its occupants.

The next step brings us directly to agentic AI. Some devices could progressively become more than connected objects capable of receiving a command. They could observe their environment, interpret certain information, and act within the limits granted to them.

An energy system could manage consumption and storage. Another could monitor security. An environmental system could optimize air quality. The vehicle could coordinate its charging periods with the home, while some appliances could postpone an operation when electricity is particularly expensive. A maintenance system could detect unusual consumption and flag that a device appears to be heading toward failure.

A local intelligence could eventually coordinate several of these functions. The home would then start to resemble a small multi-agent system in which different machines have their own information, capabilities, and levels of autonomy. This evolution immediately brings another reality to light: every new smart object also becomes a part of the computing system.

A connected lock has a physical capability. A camera processes particularly sensitive information. A charging station combines computing, communications, and electrical power. A connected vehicle adds movement to the equation. A heating system or a home battery can also produce physical consequences when a command is erroneous or malicious.

The boundary between cybersecurity and physical security thus becomes far less clear-cut. When a computing system can open a door, move a vehicle, change a temperature, cut off a power supply, or control several kilowatts of power, a digital action can directly produce a consequence in the physical world.

This reality explains why the principles of identity, authentication, least privilege, segmentation, encryption, secure updates, and monitoring must extend across the entire IoT ecosystem. The lifecycle also becomes essential, since a connected device may remain installed for many years, well beyond the period during which its manufacturer necessarily wants to support it.

Machine identity will become particularly important. In a home containing a few dozen devices, it is still relatively easy for a human to understand which pieces of equipment are present. As their number, their interactions, and their autonomy increase, it will be necessary to determine with far greater precision which system is requesting information, which machine is attempting to carry out an action, and whether it still holds the necessary authorization.

Zero Trust and Continuous Trust find a very concrete application here. The fact that a device was authorized when it was installed does not mean its trust should be permanent. Its software can change, its behavior can change, a vulnerability can be discovered, or its manufacturer can stop providing updates. The trust granted to the machine must therefore be verifiable and reassessable throughout its entire lifecycle.

Hypersecurity broadens this perspective further still. In a home that has become a distributed computing system, security can no longer be limited to protecting the router or to the quality of the Wi-Fi password. It concerns identities, devices, data, communications, cloud services, AI models, agents, updates, suppliers, and interactions with the physical world.

A compromise can also spread between these layers. A sensor supplies bad information to an AI system, which then makes an erroneous decision and sends a command to a perfectly functional piece of physical equipment. None of these elements necessarily has to be faulty on its own for the interaction to produce an undesirable outcome.

Hypersecurity then becomes a matter of overall architecture: knowing what exists, understanding the interactions, limiting privileges, segmenting environments, detecting unusual behavior, containing incidents, and maintaining the ability to regain control when an unexpected situation arises.

The smart home also raises a particularly concrete question of digital sovereignty: who owns its intelligence?

A connected home can produce a considerable amount of information about its occupants. Hours of presence, sleep habits, movements, energy consumption, visitors, vehicles, temperature preferences, voices, and images can, when combined, produce an extremely detailed portrait of daily life.

The return of part of the intelligence to the edge changes the relationship with this data. If the essential functions can be executed locally, the most sensitive information can also stay closer to where it is produced. Some processing can be carried out without continuously transmitting the data to external infrastructures.

The cloud will obviously retain an important place. Remote access, backups, updates, certain complex computations, and many specialized services will continue to benefit from external infrastructures. The interesting shift lies instead in the relationship between local and cloud.

A more autonomous home could treat the cloud as a resource it chooses to use when it provides a useful capability, rather than as the place it depends on for every one of its essential functions.

This distinction is a particularly concrete application of digital sovereignty. The home keeps its fundamental functions local, protects certain data close to its source, and uses various external services when they provide value. It also preserves, where the architecture allows it, the ability to change suppliers. Sovereignty then becomes the ability to choose, right down to our own home.

This domestic evolution may seem far removed from the technology challenges of companies and governments. It is nevertheless an excellent laboratory for what is taking shape on a much larger scale. The same questions will arise in commercial buildings, factories, energy grids, transportation infrastructure, vehicles, and cities.

Everywhere, machines will have to have an identity, access certain information, communicate with other systems, receive permissions, and sometimes make decisions without continuously waiting for human intervention. Some will operate at the edge, others will use the cloud, and many will combine the two as needed.

The challenge will therefore no longer be solely to connect billions of objects. We will have to learn to govern billions of digital participants.

In 2026, the smart home is still imperfect. Several protocols coexist, some devices remain heavily dependent on their manufacturers, and the user experience can quickly become complex. Matter continues to roll out and evolve, while local platforms also keep improving their compatibility with an extremely diverse universe of devices.

The direction the ecosystem is taking is nonetheless becoming far more interesting. Standards are advancing, devices are becoming more interoperable, processing is progressively returning to the network edge, and artificial intelligence can start to run locally. Energy systems are becoming communicative, vehicles are joining the home’s digital ecosystem, and some objects are progressively gaining the ability to take part in decisions.

The smart home could thus evolve into something far more ambitious than a collection of connected gadgets. It could become a distributed computing environment capable of sensing its context, processing part of its information locally, coordinating several systems, and acting according to the objectives set by its occupants.

This evolution is also a preview of what awaits organizations. Edge AI, secure operating systems at the edge, IAM, Zero Trust and Continuous Trust, private and sovereign artificial intelligence, agent governance, cyber resilience, and Hypersecurity will progressively become necessary to manage environments where machines no longer merely transmit information.

For Quantum Beyond, the smart home therefore offers a miniature example of a much broader challenge. Tomorrow’s digital infrastructures will be distributed across the cloud, the edge, and billions of devices capable of communicating, interpreting, and sometimes acting. Their value will depend on their ability to work together, while their security will depend on our ability to know who they are, what they can do, what information they can access, and under what circumstances their trust must be reassessed.

The real revolution of the Internet of Things will probably begin when we stop thinking of these billions of devices as mere connected objects. They will become active participants in our digital and physical environment. As we grant them more capabilities, we will also have to learn to grant them the necessary trust without ever giving up on governing it.
