No more fumbling around in the dark. Your hallway or bedroom lights switch on automatically when you walk past the motion sensor without having to flick a switch or say a word. Stop wondering if you've closed all the windows after leaving the house. Check your doors and windows at a glance with the Tapo app. The Tapo hub is the centrepiece of your Tapo smart home, connecting devices such as smart sensors, switches and buttons via an ultra-low power wireless protocol. This technology helps battery-powered devices last up to ten times longer. When the contact sensor or motion sensor detects unusual behaviour, it triggers the hub alarm (up to 90 dB) and notifies you via the Tapo app. Check the specific detection time in the Tapo app event log, no matter where you are.
