Smart home devices: the ones worth it, the ones that aren't
In one line: Start with problems, not gadgets: the four devices that earn their plug, the category to skip, and the privacy defaults to change.
The smart home market sells the future by the gadget. Most of it is a phone screen standing in for a switch you already owned. A handful of devices, though, genuinely earn their plug - and the difference between the two groups is a question: does this solve a problem my house actually has?
Worth it - the short list
Smart thermostat. The one with real money attached: heating and cooling are the home's biggest power users, and proper scheduling and away-detection shave genuine amounts off - the honest payback maths is here.
Water-leak sensors. Twenty-ish currency units apiece, placed under the washing machine, water heater and under every sink. They beep the day a hose starts dripping instead of the month you find the ceiling stain. Per pound, the best insurance in the entire smart home aisle.
Video doorbell. Real convenience and genuine deterrence, priced once. Buy the storage plan consciously - check its yearly fee before the purchase, not after.
Smart plugs. For the specific job of killing standby drain on the media centre and the desk - the measured cost of always-on devices is here - and for lamps on holiday schedules.
Worth skipping - for now
Smart fridges, washers and ovens. The screen adds cost and a future software-obsolescence problem to machines whose job was to run for twenty years without updates - the appliance-by-appliance sorting is here. Voice-everything by default. Start with the switch-shaped problems; the microphone can wait for an actual use.
The five minutes of privacy setup
Whatever you buy: change default passwords on day one, decline the data-sharing toggles during setup, turn on automatic updates, and name devices something other than your surname. A camera pointed at your street deserves a moment's thought about where its footage goes.
The pattern across all of it: buy for the leak, the bill, the package and the lock - not for the demo. One honest thermostat and two leak sensors do more for a house than a shelf of colour-changing bulbs - and they cost less together than any one of them cost three years ago.
