When the internet goes down, many smart home gadgets quietly “go dumb”: lights that ignore their schedules, thermostats that freeze, and automations that simply never fire. But it doesn’t have to be that way. In an explainer published on October 17, 2026, Engadget’s Roger Fingas lays out how to build a smart home that keeps working through an internet outage — without investing in the custom systems you only find in mansions. It’s all about anchoring your gear around the right hubs and protocols.
Why smart accessories go dumb without the internet
The reason so many accessories turn dumb, Engadget explains, is that they connect directly to Wi-Fi to fetch instructions from a cloud server. Wi-Fi devices are often the easiest to set up — but when the internet drops, or the Wi-Fi router itself hiccups, they may have no way to store and trigger automations on their own. They may not even switch on or off at scheduled times, which you’d think would be dead simple. Some simply freeze in their last state; others stop working entirely.
Usually, Fingas notes, that’s just an inconvenience. But if you’re counting on a smart home accessory for health or security, an outage can become a legitimate crisis.
Let the hubs do the talking
The core recommendation is simple: whenever possible, choose accessories that route everything through a local hub rather than straight to the cloud. These hubs still connect to the internet, but they can store and process many automations locally, as long as everything still has power.
There are exceptions. Automations that depend on live data — like current weather conditions — or that involve sharing data remotely still need an internet connection. And if you’re installing a smart security system in an area where outages are regular, Fingas is blunt: cellular backup is a must.
What the big platforms already offer
The major ecosystems already have local-hub options, though most shoppers never think of them that way:
- Apple Home: HomePods and Apple TVs can act as home hubs, enabling both remote access and local automations.
- Security cameras: Some can record to local hub storage, even if they have to go online to trigger alerts or perform advanced functions.
- Matter-enabled speakers and displays: These are technically capable of executing offline commands — though Engadget found that in practice, Amazon and Google don’t really exploit this. “We discovered this the hard way,” the piece notes.
Pick the right radio: Thread, Zigbee, or Z-Wave
The most bulletproof hubs, according to the guide, tend to be those that link local hardware not through Wi-Fi, but through Thread, Zigbee, or Z-Wave radios. All three are low-power, low-bandwidth mesh standards. A single hub can often connect many compatible accessories at once, and the mesh aspect means devices farther from the hub won’t drop off.
Of the three, Thread gets the nod as the preferable choice, since some Wi-Fi accessories can act as Thread “border routers” — bridging the local mesh to the rest of your network. That said, the guide’s author reports great experiences with Zigbee-based hubs like the Philips Hue Bridge. The only real limitation of these radio technologies is bandwidth: they’re suited to lights, locks, and sensors, not high-throughput devices like cameras.
What about the power problem?
Internet resilience is only half the equation — a hub that survives an internet outage is still useless if the power goes out. The ideal setup would pair an entirely hub-based smart home ecosystem with whole-home battery backup. But Engadget calls that unrealistic for most people: whole-home battery systems cost thousands or tens of thousands of dollars, and some accessories simply don’t exist in hub-compatible form. Unless your job or safety is at stake, the outlay probably isn’t worth it for a soundbar or light panels going dark for 30 minutes.
The workable compromise is to hunt for accessories with their own redundancy — batteries, backup controls, or both. One example from the guide: the Philips Hue Go connects to a Hue Bridge but also includes a battery so it can operate as a portable lamp. It keeps shining for hours without AC power and cycles through basic effects using an onboard button or app-based Bluetooth commands. Smart thermostats, meanwhile, will always keep operating on their last schedule as long as the HVAC system itself stays powered.
The takeaway for shoppers
You won’t be able to secure redundancy for every smart home accessory. But if you think ahead when shopping, at least some of your devices should keep running 24/7. The rule of thumb from Engadget’s October 17 guide: don’t just pick the cheapest or slickest options — look for local-hub compatibility, Thread or Zigbee radios, and battery backup on the devices that matter most.
With Apple rolling out its new HomeView hub and Home Collection accessories — all built around Thread and Matter — local-first architecture is fast becoming the default rather than the exception. The homes that stay smart through the next outage will be the ones designed for it now.
