Why it's a great deal

  • Requires eufy HomeBase to Operate: Compatible with HomeBase Mini (v4.0.5.2 or above), HomeBase 2 (v3.4.1.2 or above, released after 2021), HomeBase 3 (v3.7.2.6 or above), and HomeBase Pro (v4.1.4.3 or above). Ensure your HomeBase is updated to the latest version for optimal performance.

  • Dual-Side Detection: Supports both left and right-side installation for quick, error-free setup.

  • Convenient Bypass Button: Simply press the bypass button to temporarily deactivate the sensor, allowing you to open the door without triggering an alarm. Your other sensors remain active.

  • Long-Lasting 5-Year Battery Life: Features a CR123A battery with up to a 5-year lifespan, meaning less maintenance for you.

  • Expansive Wireless Range with HomeBase: Provides a stable connection with HomeBase at open-air distances of up to 656 ft (200 m).

  • Smart Alerts and Custom Settings: Protect your home with intelligent features—hear instant chime sounds from your HomeBase (compatible with HomeBase 2, HomeBase 3, and HomeBase Mini) when entry is detected, and create automation rules to activate cameras or lights when sensors trigger. Unlock these advanced features by updating your eufy app to v6.0.00 or above.
