Home automation developer Spencer Kittleson says core functions in his house continue to work when the internet is disconnected, using equipment he controls and local automation software. His account describes a design approach, not an industry-wide standard or a test of every smart-home product.
Home automation developer Spencer Kittleson says the core functions in his house keep working when the internet is disconnected, a design rule he has followed for about 10 years. In a report published in October 2026, he describes a system built around hardware he owns and local tools, arguing that lights and other essential functions should not depend on a vendor’s remote servers.
Kittleson’s setup includes Tasmota software on ESP boards, an MQTT message broker, Node-RED automation software and a Raspberry Pi. He says those components handle local device communication and automation. Cloud services, including Alexa and some AWS services, are also present, but he describes Alexa as an additional way to control devices rather than the only way.
His stated rules include keeping a conventional control method when adding a smart one, making configurations manageable in one place, and regularly checking that automations do not conflict. Related guidance on smart home automation devices explores tools for building connected setups. He says a wall switch and a wall dashboard remain available if Alexa or internet access fails. Examples in his report include a sprinkler controller and a garage-door automation that checks the door’s status before running a cooling sequence.
Kittleson also describes past problems that shaped the approach. He says a Nest integration stopped working after Google changed an API, and cites a Samsung refrigerator displaying a TLS certificate error and a Camp Chef grill controller that requires Wi-Fi to show its temperature. These are his examples; the report does not independently test those products or establish how broadly such failures occur.
Keeping Controls Available Offline
When a device relies on a vendor’s server, a home internet outage, service disruption or change to an integration can affect more than remote access. Depending on the product, it may also affect a feature that residents expect to use at home. Local control can reduce that dependency, while retaining ordinary switches gives residents another option if an app or voice assistant is unavailable.
The account also highlights a practical trade-off: locally managed systems can require more setup and upkeep than devices configured through a vendor’s app. Kittleson’s principles are therefore useful as questions for buyers and installers, not proof that every household needs his particular equipment. Readers can ask whether a device has a manual fallback, what functions work without internet, and whether a cloud service or account is required for routine use.

How Kittleson Built His Setup
Kittleson presents the report as a follow-up to two talks about home automation, including examples of the equipment and workflows he has used. He says his first rule—“No internet, no problem”—led to others, such as keeping the old control method when introducing a new one and making systems inexpensive to change as rooms and household needs change.
His approach does not exclude cloud products. Instead, he says cloud-based services should be optional for core tasks, and that devices needing an API should provide logs. He also favors MQTT, a publish-subscribe communication method, so devices can send information without needing a direct connection to each individual service that uses it. The source describes one household’s system; it does not compare costs, reliability or security across different smart-home designs.
““Nothing core in my house depends on a vendor’s server.””
— Spencer Kittleson, in the supplied report
Limits of One Household’s Experience
The report is an account of Kittleson’s own system, not an independent evaluation of smart-home products or a survey of how often internet outages disable devices. It does not provide reliability measurements, a cost comparison, or a security assessment of the equipment and software described. How each product behaves offline varies, and the source does not establish whether the cited vendor examples remain unresolved or affect other users in the same way.
It is also unclear how easily a typical homeowner could reproduce the system without technical experience. Kittleson describes hardware and automation tools but does not offer a controlled comparison with a fully cloud-based home. His report gives practical principles and examples, while the wider effect of those choices on reliability, privacy and maintenance remains unquantified.
Questions to Ask Before Buying
Kittleson’s report does not announce a product launch or identify a forthcoming industry change. For readers considering smart-home equipment, the next step is to check manufacturers’ documentation for which functions require an internet connection, account or cloud service. Ask whether a device still works from a physical control during an outage and what happens if its vendor ends support or changes an API.
For people already using connected devices, Kittleson’s recommendations point to reviewing automations, keeping a fallback control method and checking which routines depend on remote services. The report does not set a timetable for a broader adoption of local-first design; whether manufacturers expand offline functionality remains an open question.
Key Questions
What does it mean for a smart-home device to work without the internet?
It means that at least its core local functions, such as operating a light from a wall switch or running a local automation, remain available without an internet connection. The exact functions depend on the device.
What equipment does Kittleson use?
He describes using Tasmota on ESP boards, an MQTT broker, Node-RED and a Raspberry Pi. He also uses some cloud services, including Alexa, as optional control routes.
Does the report show that all smart-home devices need the internet?
No. It describes Kittleson’s experience and selected examples, but does not test the full market or establish how common internet-dependent functions are.
What should buyers check before purchasing a connected device?
Check which functions work offline, whether a vendor account or cloud service is required, and whether a manual control remains available if the app, internet connection or service fails.
