The TP-Link Tapo T110 is a smart contact sensor designed to keep you informed about the status of your windows, doors, cabinets, or drawers. By utilizing the Sub-1G wireless band at 868 or 922 MHz, it maintains a stable connection to a required Tapo Hub or Homebase, allowing you to monitor your home's entry points or even a refrigerator door from your smartphone via the app. This compact device measures 61.4 x 37.5 x 12.3 mm and comes in a clean white finish that blends into most interiors. Installation is straightforward using the included 3M adhesives, meaning you can set it up without drilling holes in your furniture or frames. An integrated LED indicator provides immediate visual feedback, while the system sends a notification to your phone when the CR2032 battery runs low. Because it is energy-efficient, a single battery can last up to two years, making it a low-maintenance addition for anyone looking to automate their home security or daily routines.
