Ring Window & Door Sensor — Contact Sensor with Sidewalk

Ring's newest Window & Door Sensor instantly notifies you when an entry opens, connecting directly over Amazon Sidewalk so no dedicated base station is required.

This compact contact sensor is designed to integrate with the Ring app and your Ring devices to provide immediate alerts when doors or windows are opened. Lightweight and simple to mount, it works with Amazon Sidewalk for extended range and flexible placement — just pair it to your Ring account and receive push notifications, in-app status, and the option to add professional monitoring separately. The unit is ideal for renters, homeowners, and anyone who wants discreet entry awareness without running wires or installing a separate hub.

How will this sensor alert me when a window or door opens?

When the two-piece sensor (magnet and body) separates because a door or window opens, the device sends a signal through Amazon Sidewalk to your Ring app. You get near-instant push notifications and an activity log entry so you can check when the event happened and where.

• Instant push notifications to Ring mobile app and linked devices
• Event history recorded in the Ring app for review
• Works with other Ring devices for automated routines and scenes

Do I need a base station or special wiring to install it?

No separate base station or wiring is required — the sensor communicates over Amazon Sidewalk after enrollment in your Ring account. Installation is quick: mount the two components on the frame and sash with included adhesive or screws, align them, and follow the Ring app setup prompts.

• Mounts in minutes with adhesive or screw options
• No low-voltage wiring or professional install needed
• Uses Amazon Sidewalk for connectivity; coverage depends on Sidewalk availability

Can this sensor work with monitoring services or other Ring gear?

Yes — the sensor integrates into the Ring ecosystem and can trigger automations with compatible Ring devices. You can also enroll in Ring's optional Pro Monitoring plan (sold separately) to get professional emergency response without a long-term contract.

• Triggers routines with Ring cameras, alarms, and lights
• Optional 24/7 Pro Monitoring add-on available for emergency response
• No multi-year contracts required for Pro Monitoring

What should I know about range, battery life, and coverage?

The sensor is battery-powered for flexible placement; battery life varies with activity but is designed to last many months under normal usage. Because it uses Amazon Sidewalk instead of a local hub, coverage is broader in many environments, although actual reception depends on Sidewalk availability in your area.

• Battery-operated for tool-free installation and flexible placement
• Works over Amazon Sidewalk — coverage may vary by location
• Low-battery alerts in the Ring app for timely battery replacement

Who is this for? The Ring Window & Door Sensor (newest model) suits anyone looking for a simple, unobtrusive way to know when entrances open — renters who can't install hardwired systems, homeowners seeking extra perimeter awareness, and existing Ring users who want tighter integration without adding a hub. It’s also useful for people who want an affordable entry sensor that pairs with smart home routines and offers the option of professional monitoring when needed. Note: Amazon Sidewalk is required for use and coverage may vary, and Pro Monitoring is sold separately.
