Smart home devices have gone from novelty to mainstream, and the range is bewildering. Before spending money on things that end up in a drawer, here’s an honest look at what’s genuinely useful for most households and what’s more trouble than it’s worth.
What “smart home” actually means
Smart home devices are gadgets that connect to your WiFi and can be controlled remotely, from your phone, from a voice assistant like Alexa or Google Home, or automatically on a schedule.
The basic idea is convenience: turn off the lights without getting up, see who’s at the door when you’re not home, get a notification when the washing machine finishes. For some people these things genuinely improve daily life; for others they add complexity without much benefit. It depends what you want from it.
The things most people find genuinely useful
Smart plugs
Smart plugs are probably the best starting point. You plug them into a normal socket and plug a device into them (a lamp, a fan, a TV) and you can then turn that device on and off from your phone or with a voice command, or set it on a schedule.
They’re inexpensive (around £10-15 each), work with any device, and don’t require any changes to your home’s wiring. If you want to try smart home tech without committing to a whole ecosystem, start here.
Common uses: lamps that come on at dusk, electric heaters that turn off automatically, Christmas lights on a schedule.
Smart bulbs
Smart bulbs screw into existing light fittings and let you change brightness and colour from your phone. Some connect directly to WiFi; others use a hub that you plug into your router.
The main advantage over a smart plug on a lamp is that you can dim them and change the colour temperature, warmer light in the evening, brighter light for working. Brands to look at: Philips Hue (reliable, widely supported, but more expensive), IKEA TRÅDFRI (cheaper, solid quality), and various WiFi bulbs from brands like TP-Link Tapo.
One thing to be aware of: if someone turns the light off at the wall switch, the bulb loses power and won’t respond to your phone or voice commands until it’s turned back on. This catches people out.
Video doorbells
A video doorbell shows you on your phone who’s at the door, lets you speak to them through the doorbell, and records a short clip when someone rings. Useful if you miss deliveries, want to see who’s calling before answering, or want a record of activity at your front door.
Ring and Google Nest are the most widely used. Ring works with Alexa; Nest works better with Google Home. Both require a subscription for cloud video storage, though basic live view is usually free.
Smart speakers and voice assistants
Amazon Echo (Alexa) and Google Nest speakers let you control compatible smart devices by voice, play music, set timers, and answer questions. They’re most useful as a hub for other smart devices (“Alexa, turn off the living room lights”) rather than as standalone gadgets.
If you’re going to buy smart home devices, it’s worth picking one ecosystem early (Amazon or Google) and sticking to it, as mixing them can cause compatibility headaches.
What’s more complicated than it looks
Smart heating systems
Devices like Hive and Nest thermostats can save energy and are genuinely useful, but installation sometimes requires a professional unless you’re comfortable with your boiler’s wiring. Worth getting properly installed rather than attempting it as a first DIY job.
Smart locks
Keyless entry sounds appealing, but smart locks vary enormously in quality and security. Some are excellent; others have been shown to have security vulnerabilities. Research carefully before trusting one on your front door.
Whole-home systems
Large ecosystems (Apple HomeKit, Google Home, Amazon Alexa) that control dozens of devices simultaneously can be impressive but are also complex to set up and troubleshoot. Better to start simple and expand than to try to smart-home the whole house at once.
Things to think about before buying
Will it actually connect to your WiFi? Most smart home devices need 2.4GHz WiFi, not 5GHz. If your router is older or in a different part of the house, check the signal reaches where you want to use the device.
Which voice assistant do you want? Alexa (Amazon Echo) and Google Assistant (Google Nest) work with different ranges of devices. Decide which you prefer before buying devices tied to one ecosystem.
Is there a subscription? Many devices offer full features only with a monthly subscription. Factor this in when comparing prices.
What happens if the internet goes down? Most smart home devices stop working entirely without an internet connection, including ones in your own home. Worth considering if reliable internet isn’t guaranteed.
