In this review I'll use SwitchBot door contact and motion sensors to setup smart home automation routines using Amazon Alexa and the SwitchBot app to turn on lights when I open the door or shut lights off when occupancy isn't detected in the room.

Renters who can't replace their switches or homeowners without neutral wires needed for smart switches have trouble installing smart switches in their homes. Switchbot makes a unique product that allows you to convert your dumb switches into smart switches.
