Description
The SONOFF SNZB-04P is a Zigbee 3.0 door and window sensor that reports the open/closed status of doors, windows, drawers and cabinets in real time. It sends instant app notifications through eWeLink, can turn on lights automatically when a door or window is opened, and can trigger audible and visual alarms for unauthorized entries.
Built-in tamper protection notifies you immediately if the sensor is tampered with, and the CR2477 battery provides more than 5 years of use. Scenes between the SNZB-04P and other Zigbee devices keep working locally even if the network is disconnected, as long as the devices are powered on.
Note: a Zigbee gateway is required (see "Works With" below). The model number on the packaging and printed materials (including the manual) may differ due to a labeling update; the product appearance and functionality remain unchanged.
