Smart home technology is at the stage where it mostly works, occasionally does not, and sometimes stops working entirely because a company changed its plans.
Building something that still works in five years takes a few deliberate choices.
Start from an annoyance, not a product
The devices that get used are the ones solving something that genuinely irritates you.
Heating control is the clearest case. Room-by-room control and proper scheduling saves money and improves comfort, and the payback is measurable.
Lighting on schedules for security and convenience. Genuinely useful, particularly for outside lights and for making an empty house look occupied.
A video doorbell if you miss deliveries or are frequently away. One of the most-used categories for good reason.
Leak and smoke detection that alerts your phone. Cheap, and the one category where the device might save you thousands.
Things bought because they connect to an app — the kettle, the curtains, the bin — get used for a fortnight and then live as an extra step between you and the thing you wanted to do.
The question that matters most: what happens if the company stops?
Many devices depend entirely on a manufacturer's cloud service. The app talks to their servers; the servers talk to the device. If the service ends, the device becomes an ornament.
This is not hypothetical. It has happened repeatedly, including to well-funded products from large companies, sometimes with a few months' notice and sometimes with none.
Before buying, ask: does this work if the internet is down? Does it work if the company disappears?
Devices that can operate locally — controlled from within your own house, without a round trip to a server — are considerably safer investments, and they are also faster and more private.
Standards help, cautiously
Industry standards for smart home interoperability have improved the situation, and devices supporting them are more likely to keep working with something even if their original manufacturer withdraws.
Support varies in practice, and "supports the standard" sometimes means the basic functions work and the interesting ones do not. Worth checking specifics rather than trusting a logo on the box.
Broadly: prefer devices supporting an open standard, and prefer ones that also work locally.
Pick one ecosystem
The most common cause of a smart home becoming annoying is three apps for four devices.
Decide on one platform — one of the major voice assistants, or a local hub — and buy devices that work with it. The convenience of everything in one place is worth accepting a slightly narrower choice.
If you are technically inclined, a local hub running open software gives you the most control and the least dependence on any company. It requires more setup and is genuinely more durable.
Privacy, thought about in advance
Smart devices collect more than people assume: when you are home, when you go to bed, what your camera sees, what a microphone hears.
Practical positions:
- No microphones or cameras in bedrooms and bathrooms. Simple rule, worth keeping.
- Read what a manufacturer says it collects, before buying rather than after.
- Prefer devices that process locally where the option exists.
- Be aware that camera footage is stored on somebody's servers and can be accessed by them.
- If you have visitors or lodgers, tell them what is recording.
A device that works without the internet is more private, faster and still working in five years. Those three benefits come from the same property.
Keep them off your main network
Smart devices are frequently the least maintained equipment in a house. Some receive updates for years; some receive none.
Put them on your guest network so a compromised device cannot reach your computers or files. Most routers make this straightforward, and it is the single most useful thing you can do — see home network security basics.
Also: change default passwords, enable multi-factor authentication on the accounts, and enable automatic updates where offered.
The practical order
- Get the network right first. Smart devices spread across the house need coverage everywhere, which is a wi-fi problem before it is a smart home one — see home wi-fi coverage.
- Start with one thing that solves a real annoyance.
- Live with it for a month before adding more.
- Stay within one ecosystem.
- Put everything on the guest network as you go.
What to be wary of
Subscriptions for features that used to be included. Common with cameras, where recording history moves behind a monthly fee.
Devices requiring an account for basic function. A light bulb should not need a login.
Anything replacing a working mechanical system with an electronic dependency. Smart locks in particular deserve careful thought about what happens when the battery dies or the phone is lost.
Very cheap unbranded devices. The security is frequently poor and the app may send more data than you would like.
