This battery-powered Zigbee 3.0 contact sensor helps you monitor doors, windows, baby gates, drawers, mailboxes, and other entry points so you can build smarter alerts, routines, and everyday automations with reliable local control.

Whether you want to improve home awareness, automate lights and notifications, or add simple security-focused routines, this compact sensor makes it easy to detect when something opens or closes. It works as part of a Zigbee-based smart home and is ideal for users building a responsive Home Assistant setup with privacy, flexibility, and local automation in mind.

Reliable Open and Close Detection for Everyday Automation

This Zigbee contact sensor is designed to detect the open or closed state of doors, windows, and other movable entry points. Once paired with your compatible Zigbee setup, it can report status changes quickly and help trigger automations based on real activity in your home.

Use it to automate lights when a door opens, send alerts when a mailbox is accessed, monitor a nursery gate, or trigger a notification if a window is opened unexpectedly. It is a simple but powerful device for making your Home Assistant setup more aware of what is happening around your home.

Works with Home Assistant

This Zigbee Door and Window Sensor is a practical choice for users who want dependable local smart home control through Home Assistant. When paired to a compatible Zigbee coordinator, it can be integrated into dashboards, automations, routines, and alerts for a wide range of use cases.

It is especially useful for automation scenarios such as:

• Sending an alert when a door or window is opened
• Turning on lights when a closet, cabinet, or entry door opens
• Monitoring baby gates or nursery access points
• Detecting mailbox activity
• Creating away-mode or security routines based on door and window state
• Tracking drawers, storage areas, or other access points

Because it uses Zigbee 3.0, it supports low-latency local communication and fits well into smart home environments focused on reliability and privacy.

Compact, Flexible, and Easy to Place

The sensor is compact enough to fit neatly on many doors, windows, cabinets, and frames without drawing much attention. It includes adhesive backing for simple installation, making it easy to mount without complicated tools or wiring.

This allows you to place the sensor in a variety of practical locations throughout the home, whether you are monitoring a front door, a sliding window, a nursery gate, a drawer, or even a mailbox lid.

Battery-Powered Convenience

This contact sensor is powered by a CR2032 battery, which is included. Its battery-powered design makes installation straightforward and gives you flexibility to mount it where detection is most useful without needing direct power access.

That makes it a convenient option for renters, homeowners, and anyone looking to add smart home awareness to more parts of their living space.

Built for Smart Alerts and Routines

A door and window sensor is one of the most useful building blocks in a smart home system. By knowing when something opens or closes, Home Assistant can respond in ways that feel immediate and practical – whether that means sending a notification, changing a light state, starting a timer, or triggering a larger automation sequence.

This Zigbee contact sensor is ideal for users who want to create useful, low-friction automations that improve convenience, visibility, and peace of mind throughout the day.
