Smart home devices can save you time and effort, automating everyday tasks and leaving you with more time for the things that matter. The downside is that they can be expensive (some smart locks cost more than your front door), they often require some DIY experience, and fitting them usually means replacing your existing switches, lights, and other devices – even if they're in perfectly good condition.
Although devices like the best smart lights might save energy in the long run, throwing out functional curtains, switches and bulbs to replace them with smart versions would have a far greater environmental impact. Thankfully, there's another option.
