Smart home deals are plentiful during Amazon’s October Prime Day, but not every device is worth the money. After years of testing home technology, several factors stand out when assessing these gadgets, including real-world energy and cost savings, everyday usefulness and features that help protect privacy.
The selections below range from budget buys costing less than a takeaway meal to premium upgrades for those willing to spend more. Each one has passed practical testing in a genuine home setting.
Smart plugs with energy monitoring
The Tapo Smart Plug two-pack remains a reliable first-time upgrade. Smart plugs add app-based scheduling and remote control, typically for around £8 to £12, and pair well with common household appliances, even something as simple as a lamp.
What sets this two-pack apart is its energy monitoring feature, which few plugs offer. It is genuinely useful for identifying energy-hungry appliances around the home, such as space heaters brought out during colder weather. The combination of a low price and energy tracking makes it an easy recommendation.
A thermostat that pays for itself
The Google Nest Learning Thermostat (4th gen) represents a significant improvement over traditional heating and cooling controls. It offers eco and vacation modes, simpler scheduling through an app, voice control and algorithms that learn when a home is active or quiet, adjusting automatically.
Many smart thermostats pay for themselves within a year or two through energy savings. This Nest model is among the most advanced available, featuring a bright dial display and optional connections to other appliances. It makes heating easier to manage while also looking the part.
Smart lights for every season
For anyone whose old festive lights are due for replacement, the Nanoleaf Smart String Lights for indoor use are discounted during the event. Their durable LEDs can display any colour chosen through the app, and several lengths are available, with the strongest saving on the extra-long version.
The app allows users to set dynamic effects, sync the lights to music or create their own patterns. With virtually limitless colours and themes, the lights suit Halloween, Christmas, New Year and any other colour-themed occasion, meaning they can stay up throughout the year if desired.
These four devices are all available at reduced prices during Amazon’s October Prime Day event in 2026.
