The TP‑Link Tapo Smart Contact Sensor T110 is a small wireless sensor that detects when doors, windows, cabinets, or other openings are opened or closed and sends instant alerts to your phone via the Tapo app. It’s battery‑powered, easy to install with adhesive, and can trigger smart actions (like turning on lights) when linked with a compatible Tapo smart hub and other devices as part of a smart home setup.
