The topic Stop treating the Raspberry Pi 5 as a smart home hub — it’s actually built for… is currently the subject of lively discussion — readers and analysts are keeping a close eye on developments.
This is taking place in a dynamic environment: companies’ decisions and competitors’ reactions can quickly change the picture.
The Raspberry Pi has always been easy to recommend for home automation, but the Raspberry Pi 5 complicates that recommendation in a useful way. If all you need is a box to run Home Assistant, a few Zigbee devices, and some basic automations, it’s more machine than the job really needs. A Raspberry Pi 4 can still handle that workload comfortably, and older models can remain useful for modest setups. The Pi 5 starts to make more sense when the home automation hub becomes part of a wider home lab rather than a single-purpose appliance.

That distinction matters because smart home setups rarely stay small forever. You start with a few lights, then add sensors, dashboards, network monitoring, DNS services, backup jobs, and small utilities that make the whole house easier to manage. At that point, the hub is no longer just listening for motion events or turning on lamps at sunset. It becomes the always-on computer that ties everything together, and that’s where the Raspberry Pi 5 finally earns its extra headroom.

Home Assistant isn’t particularly demanding when it’s doing the basics. Automations are usually lightweight; sensors report in small bursts; and most integrations spend more time waiting for events than crunching data. A Raspberry Pi 5 can run that workload without breaking a sweat, which sounds good until you realize the same is true of cheaper, older hardware. For a simple smart home, the extra CPU power mostly sits there politely waiting for something interesting to happen.
That’s why the Raspberry Pi 5 can feel a little mismatched as a pure automation box. It brings a faster processor, better I/O, and a more capable overall platform, but turning on a hallway light doesn’t require that kind of muscle. Even dashboards and add-ons usually aren’t enough to justify the upgrade on their own. If the goal is only reliable automation, stability matters far more than raw performance.
The problem is that “only home automation” is rarely where things stop. Home Assistant has a way of becoming the front door to everything else running on the network. Once you have one reliable always-on device, it’s tempting to add a few more jobs to it. The Raspberry Pi 5 is overkill for the original task, but that overkill becomes useful when the scope expands.
The Raspberry Pi 5 works best when it’s treated as a compact service hub rather than a dedicated switchboard for smart devices. It has enough performance to run Home Assistant while also handling supporting services that make the smart home feel more complete. That could mean MQTT, a dashboard, network monitoring, a lightweight database, or other utilities that support the rest of the setup. None of those tasks is huge on its own, but together they benefit from the Pi 5’s breathing room.
This is where the Raspberry Pi 5 starts to feel less wasteful. The extra performance doesn’t just make Home Assistant faster; it gives you room to build around it without immediately needing another box. You can run more add-ons, keep logs for longer, and experiment with services that would feel cramped on weaker hardware. It becomes easier to treat the Pi as a small control plane for the home instead of a single-purpose appliance.
That flexibility also changes how you think about reliability. When the same machine hosts multiple small services, you’re not chasing performance for bragging rights. You’re trying to avoid a setup where every minor addition turns into a resource negotiation. The Raspberry Pi 5 gives those supporting services enough space to coexist, which makes the whole system feel less fragile.
There’s a practical advantage to keeping small infrastructure tasks on one Raspberry Pi 5. Home labs can sprawl quickly, especially when every new idea gets its own machine, VM, or container host. That’s fun for testing, but it can become a maintenance tax when you only wanted a few reliable services. A Pi 5 can absorb many of those small jobs without turning the setup into a rack-scale science project.
This does not mean the Raspberry Pi 5 should replace a real server or NAS. It’s still a small board with limits, and those limits show up if you expect it to handle heavy virtualization, large storage jobs, or serious media workloads. But for services that need to be always available and don’t need much power, it’s a good fit. It can sit quietly, use little electricity, and keep the boring parts of the home lab running.
The best version of this setup is intentionally restrained. Home Assistant can remain the star, while the Pi also runs the supporting cast that makes it better. That might include monitoring, local DNS helpers, dashboards, or other light services that benefit from being nearby. The result is a cleaner home lab where the Pi 5 handles the glue work instead of pretending to be a full server.
Of course, plenty of people don’t need a Raspberry Pi 5 for this. If your smart home is small, a Raspberry Pi 4 remains a sensible choice. It can run Home Assistant well, especially with decent storage and a clean setup. For many households, spending more on a Pi 5 won’t noticeably improve daily automation.
There’s also the cost question. By the time you add a case, a power supply, storage, and cooling, the Pi 5 can creep into mini-PC territory. At that point, it’s reasonable to ask whether a used tiny desktop or low-power mini PC would be the better buy. Those systems often provide more memory, better storage options, and standard x86 compatibility.
That makes the Raspberry Pi 5 a weaker recommendation if you’re buying strictly for value. It’s not the cheapest way to run Home Assistant, nor the most powerful small server for the money. Its appeal depends on what you want from the device beyond automation. If that answer is “nothing,” the Pi 5 may be the wrong kind of generous.
The reason I still like the Raspberry Pi 5 in this role is that home automation tends to grow sideways. You don’t necessarily add one giant workload. You add ten small ones, then forget how many of them now depend on that little board staying healthy. The Pi 5 gives you more room before those tiny demands start piling up into a problem.
If you’re using a Raspberry Pi 5 for home automation, don’t stop at Home Assistant. It’s a good place for lightweight supporting services like MQTT, uptime monitoring, local dashboards, or DNS helpers, as long as you keep the workload sensible. The trick is to group services that support your smart home, not to dump every random home-lab experiment onto the same board. That keeps the Pi useful without turning your automation hub into another maintenance project.
It also encourages a more useful kind of experimentation. You can test add-ons, run extra monitoring, and try adjacent services without immediately moving everything to another machine. That matters because the best home lab ideas often start as small conveniences. A Raspberry Pi 5 gives those conveniences enough space to prove whether they’re worth keeping.
The extra performance also makes the experience feel smoother in ways that don’t always show up in specs. Restarts can feel less painful, dashboards can respond more quickly, and add-ons have more room to operate without crowding each other. None of that is essential for a basic automation setup, but it matters once the hub becomes part of your daily infrastructure. The Pi 5’s overkill becomes a buffer against the slow creep of ambition.
The Raspberry Pi 5 is not the most efficient answer to the question, “What should run Home Assistant?” A cheaper Pi, a used mini PC, or an existing server can all be better choices depending on the setup. But that question is too narrow once the smart home becomes part of a broader home lab. The better question is whether you want one small, reliable device that can run automation and the extra services that make it more useful.
That’s where the Pi 5 lands well. It’s too much for home automation in isolation, but it’s just right for the hub that gradually becomes more than home automation. It gives you enough headroom to consolidate small jobs, experiment without rearranging the whole network, and keep the household’s quiet infrastructure in one dependable place. For a smart home that keeps expanding, that kind of overkill starts to look less wasteful and more like planning ahead.
The Raspberry Pi 5 is so powerful it shouldn’t be wasted on simple home automation; use it as a central hub for your smart home and home lab.
