Smart living
Smart devices save money when they change behaviour. Here is where that happens — and where a plain LED and a light switch still win.
Schedules, dimming and away modes stop lights burning through the night. Best in rooms where lights get left on rather than everywhere.
Automatic setbacks on the largest load in the house. Check for a C-wire and for utility rebates before buying.
Measure what a device actually draws over a week. The cheapest way to replace energy folklore with data.
One smart switch on a circuit of plain LEDs is often better value than replacing six bulbs — and the wall switch keeps working for guests.
A fan lets you raise the thermostat a few degrees in summer at a fraction of the draw of air conditioning. Turn it off when the room is empty — fans cool people, not rooms.
Cameras, sensors and smart locks are bought for peace of mind, not savings. Door and window sensors do help by flagging when heating or cooling is escaping.
Start with the categories that change how much electricity you use, not just how you switch it on.
Lowest cost per watt savedRoughly 80% less lighting energy than incandescent, plus schedules and dimming.
Works with existing fixturesControl whole fixtures at the wall — dimming cuts draw and extends lamp life.

Ideal for halls, closets, garagesLights that turn themselves off in the rooms everyone forgets.
Great for TV and office clustersKill standby draw across an entire desk or media centre in one move.
Adds schedules, dimming and away-mode automation on top of LED efficiency. Best in rooms where lights get left on.
