TP-Link Tapo T100 Motion Sensor

This compact Tapo motion sensor connects to a Tapo Hub to add motion-triggered automation and security to indoor spaces, helping you control lights and other smart devices based on presence. It emphasizes long battery life and flexible placement, making it useful for hallways, entryways, and rooms where hands-free control is helpful.

Key Points

The sensor uses a Sub-1G low-power wireless protocol to communicate with the hub, which the manufacturer says improves battery life and extends coverage compared to direct Wi-Fi connections. It detects movement across a wide 120° field and can sense motion up to 7 meters away. The detection range is adjustable to 3 m, 5 m, or 7 m so you can tailor sensitivity to the area you want to monitor. 🛋️

Installation is simple thanks to a compact body, a magnetic base, and 3M adhesive that let you mount the unit on walls, ceilings, or other flat surfaces without tools. Real-time notifications are sent through the Tapo app when the hub triggers an alarm within the configured schedule, allowing immediate awareness of activity. ⚡

A practical nuance to consider is that the sensor requires a Tapo H100 hub sold separately and a secure 2.4 GHz Wi-Fi connection for the hub to operate. This setup improves battery performance but adds an extra component to the system.

Benefits

Adjustable sensitivity and angle make false positives less likely in rooms with pets or frequent movement close to doorways. The ability to use the sensor as a condition in smart actions lets you automate lighting and scenes when motion is detected, freeing you from manual switches. Notifications can be limited to specific time windows, which helps avoid alerts during expected activity and focuses the device on relevant hours.

Battery performance is notable for a battery-powered sensor. According to the manufacturer, a single CR2450 battery is included and can last up to two years based on testing with 100 triggers per day. For locations where frequent triggers are expected, consider that heavy daily use will reduce this runtime.

Technical Specifications

• Name: Tapo T100 (Motion Sensor)
• Detection angle: 120°
• Detection range: 3 m / 5 m / 7 m (adjustable)
• Battery: CR2450 included, up to 2 years (manufacturer testing at 100 triggers/day)
• Connectivity requirement: Requires Tapo Hub H100 and secure 2.4 GHz Wi-Fi for the hub
• Mounting options: 3M adhesive and magnetic base for indoor installation.

Usage Recommendations

Place the sensor at a height and angle that covers the main approach path to the area you want monitored, and use the adjustable range settings to reduce triggers from adjacent rooms. For entryways and corridors, start with the 5 m setting and reduce to 3 m if the sensor picks up traffic from nearby zones. When integrating with smart actions, test the timing and automation rules during daytime before relying on them for night use.
