Tapo T100 Motion Sensor

The Tapo T100 is a battery-powered motion sensor for Tapo smart-home automations. It requires a Tapo Hub, sold separately, and detects movement within a claimed 120-degree angle and up to 7 meters, with adjustable detection distance.

At a glance

Uses Sub-1G wireless to communicate with a required Tapo Hub rather than connecting directly to Wi-Fi.
Motion can trigger Tapo smart-device actions, hub alarms and app notifications during a selected time period.
Detection distance can be set to 3m, 5m or 7m, and the sensor body can be adjusted.
The claimed battery life of up to 2 years assumes fewer than 100 motion detections per day.
