The Best Smart Home Sensors for Alexa, HomeKit, and SmartThings
This guide reviews and compares smart home sensors across four categories—motion, temperature/humidity, and door/window sensors—testing models from brands like TP-Link Tapo, Philips Hue, and Aqara. The sensors can trigger automations (like turning on lights when motion is detected), send smartphone alerts for security monitoring, and support integration with major platforms like Alexa and Google Home, though most require a compatible hub to function. The guide highlights top picks in each category based on factors like alert speed, app usability, price, design, battery life, and automation reliability.
