Smart plugs
Wi-Fi smart plugs compared on app quality, voice support and price.
All smart plugs do the same thing, switching one outlet on a schedule or by voice. What differs is the app and the ecosystem. Check that the plug supports your voice assistant before buying, and note that most only join 2.4 GHz Wi-Fi networks. Multi-packs bring the per-plug price down sharply.
