Yes a physical switch will CUT the power from reaching the globe, but a smart switch is a device of its own and will normally need its own power supply to receive signal etc etc, which consist… Read more »

After buying these, two died after about 10 minutes of use. Replaced with the Sonoff MiniR2 which works flawlessly.
