Ring Mailbox Sensor — Mailbox Motion Detector

Ring Mailbox Sensor is a compact, battery-powered motion detector that sends real-time alerts to your Ring app when your mailbox opens.

Monitor deliveries and know when mail arrives without opening the mailbox. The Ring Mailbox Sensor pairs wireless convenience with smart‑home connectivity: it runs on a long-life battery (up to three years under typical use), links using Amazon Sidewalk for wide-range connectivity, and integrates with Alexa and other Ring devices for coordinated responses.

How will the Mailbox Sensor notify me when my mail arrives?

The sensor detects motion when the mailbox lid or door is opened and pushes an instant notification to the Ring app on your phone. You can also receive Alexa announcements if you link the sensor to an Alexa-enabled device.

• Push notifications to the Ring app in real time
• Optional Alexa voice announcements when paired
• Customizable motion sensitivity to reduce false alerts

Do I need a Ring Bridge, Alarm Pro, or other hub to use it?

In most setups you do not need an additional Ring hub because the Mailbox Sensor works with Amazon Sidewalk out of the box. If Sidewalk is unavailable, you can use supported Ring network devices for local connections.

• Built-in Amazon Sidewalk compatibility for extended range
• No Ring Bridge or Alarm Pro required when Sidewalk is available
• Can fall back to local Ring devices if needed

Can it work with other Ring devices and automations?

Yes—pair the Mailbox Sensor with Ring cameras, doorbells, or compatible smart lights to trigger actions when your mailbox opens. For example, start a recording or turn on exterior lights for a coordinated response to deliveries.

• Trigger Ring cameras to record when motion is detected
• Activate Ring Smart Lighting on mailbox events
• Use the Ring app to create routines and adjust triggers

How long does the battery last and how customizable is the sensor?

The Mailbox Sensor is designed to run up to three years on its included battery under typical conditions. In the Ring app you can fine-tune motion sensitivity and control notification preferences so the sensor fits your routine and location.

• Up to three years of battery life with standard usage
• Adjustable motion sensitivity settings in the Ring app
• Simple battery replacement when needed

Who is this for: The Ring Mailbox Sensor is aimed at homeowners, renters, and small-business owners who want a straightforward way to know when mail or packages arrive without constant physical checks. It suits people who already use Ring or Alexa devices and anyone who needs a low-maintenance, long‑battery life sensor that integrates into a broader smart‑home or security setup.
