Connected lighting is among the first things people automate, partly because it is visible and partly because the daily pattern is so regular. In much of Canada the gap between summer and winter daylight is wide, so lights are simply used more for several months. Automating that use, rather than adding new lighting, is where the value sits.
Smart bulbs or smart switches?
This is the decision that shapes everything else. Each approach has a clear strength and a clear limitation.
| Approach | Strength | Limitation |
|---|---|---|
| Smart bulb | Per-bulb colour and dimming; no wiring | If the wall switch is off, the bulb has no power |
| Smart switch | Controls the whole fixture; familiar wall control | Installation; may need a neutral wire |
A common compromise is a smart switch for fixtures everyone uses by the wall, and smart bulbs in lamps and accent fittings where colour or fine dimming is wanted.
Standby draw is real but small
A connected bulb or switch keeps its radio awake to receive commands, so it draws a small amount of power even when the light is off. For a single device this is minor; across many devices it adds up modestly. The energy saved by switching to efficient LED lighting and by turning lights off through automation generally outweighs that standby draw, but it is honest to acknowledge the draw exists.
Automations that hold up over a season
The most durable lighting routines are the unglamorous ones. The examples below are written as plain rules.
Sunset triggers are useful in a place where sunset moves by hours across the year, because a fixed clock time drifts out of step with the actual daylight. Tying lights to sunset keeps the behaviour consistent through the seasons without manual adjustment.
Colour temperature and the long evening
Many connected bulbs can shift from cooler to warmer light. Warmer tones in the late evening are a common preference, and an automation can make that shift gradual rather than something to remember. This is a comfort feature rather than an energy one, but it is among the more appreciated uses during dark months.
