ThirdReality Zigbee Motion Sensor R1 – Real-time Alerts & Adjustable Sensitivity

Overview

Meet the ThirdReality Zigbee Motion Sensor R1, a compact, battery-powered sensor designed to help you monitor spaces in real time without wires. Its clean, unobtrusive form fits modern interiors while delivering timely motion insights that can power smarter routines and respond to activity as it happens.

Built to work with Zigbee hubs and Echo devices with built-in Zigbee hubs, R1 integrates with popular ecosystems such as Home Assistant, SmartThings, Hubitat, and Homey. This broad compatibility lets you weave motion events into your existing automation without changing your preferred control setup.

Key capabilities

• Real-time Motion Detection: Accurate human movement detection that remains effective regardless of heat or sunlight exposure.
• Long Range & Adjustable Sensitivity: Coverage from 1.5 to 9.5 meters, adjustable with simple onboard buttons—no app required.
• Custom Automations: Pair with a compatible hub to trigger lights, notifications, or scene changes when motion is detected.
• Battery-powered Flexibility: Runs on three AA batteries, enabling wire-free placement with up to about a year of typical use before replacement.
• Expanded Smart Assistant Support: When used with the optional Smart Bridge MZ1, it can integrate with Apple HomeKit, Google Home, Amazon Alexa, and SmartThings, plus OTA software updates.

Placement and everyday use

The absence of cables makes it easy to place on a shelf, in a corner, or on a wall mount. The onboard controls allow you to fine-tune the detection range quickly, even without opening the app. The result is a flexible sensor that adapts to different room layouts and activity levels.

What this means for your smart home

By combining reliable motion sensing with automation, you can create routines that save energy, reduce false alarms, and improve convenience—without relying on a single device or vendor. The R1 is designed to complement your existing hub ecosystem while offering a straightforward path to smarter, more responsive spaces.

Reliability and updates

With Zigbee 3.0 compatibility, the sensor reliably exchanges signals with compatible hubs, and OTA updates keep firmware current, expanding features over time. Battery life depends on activity and settings.
