TP-Link Tapo T100 Smart Motion Sensor

TP-Link Tapo T100 Smart Motion Sensor TP-Link Tapo T100 Smart Motion Sensor is a compact, affordable, battery-powered motion detector designed for smart home automation and basic security. It works within the Tapo ecosystem and requires a Tapo Hub (such as the H100) to connect to your Wi-Fi and enable automations. Key Features Detection: Up to 7 meters (23 ft) range with 120° wide-angle view. Sensitivity: Adjustable in 3 levels (low/medium/high) to reduce false triggers (e.g., from pets or curtains). Battery: CR2450 coin cell — up to 1–2 years of life (depending on usage and settings). Mounting: Magnetic base + 3M adhesive + freestanding options. Compact and easy to hide. Automations: Triggers Tapo lights, switches, sirens, or notifications when motion is detected. Supports schedules and activity zones in the Tapo app. Alerts: Real-time push notifications to your phone. Integration: Works with Alexa, Google Assistant, and other Tapo devices. Sub-1GHz wireless for better range and battery efficiency than Wi-Fi sensors. Dimensions: 42.3 × 42.3 × 34 mm (very small). Pros Excellent value and reliable performance for the price. Long battery life and easy installation. Quick response time for lighting automations (e.g., hallway lights turning on automatically). Adjustable sensitivity helps minimize false alarms. Great for hands-free lighting, energy saving, and entry alerts. Cons Requires a Tapo Hub (extra cost if you don’t have one). No built-in camera or siren (pure sensor only). Detection is PIR-based (infrared) — can be affected by heat sources or blocked by obstacles. Best suited for indoor use (though some users place it in sheltered outdoor spots). This is one of the best entry-level smart motion sensors for automating lights, notifying you of movement, or building simple security routines in the Tapo app. It’s ideal for beginners expanding their smart home.
