eufy Entry Sensor E20

The eufy Entry Sensor E20 is a wireless door and window sensor that detects entry and sends alerts to your HomeBase hub. It mounts on either the left or right side of a door frame. The sensor uses a CR123A battery with an expected lifespan of five years. It communicates with HomeBase Mini, HomeBase 2, HomeBase 3, and HomeBase Pro (specific firmware versions required). A bypass button lets you temporarily disable the sensor without affecting other connected devices. The wireless range extends to 200 metres in open air. Compatible with the eufy app (v6.0.00 or above), it supports automation features including instant chime alerts and triggering of cameras or lights when entry is detected.
