## Overview

The THIRDREALITY Zigbee Motion Sensor is a pet-friendly, battery-powered PIR sensor compatible with Zigbee 3.0 hubs and Echo devices with built-in Zigbee. It detects motion up to 20 feet with a 120° angle, supports customizable Alexa routines for smart lighting and alerts, and offers a 2-year battery life for reliable, maintenance-free operation.

## Description

Third Reality’s Wireless Motion Sensor for Zigbee is a PIR (Passive Infra-Red) sensor capable of detecting motion up to 30 feet away with a 120° viewing angle. This motion sensor is a standard ZigBee sensor, it can work with echo devices with build-in ZigBee hub, or 3rd party ZigBee hub like SmarrtThings. Using the Alexa app, you can then create Routines which are triggered when (i) motion is detected or (ii) motion is not detected for a period of time. When creating a new routine using the Alexa app, under Routines, tap “When this happens”, select “Device”, select your motion sensor then decide what type of action to take when motion is either detected or not detected. For more information on how to create routines and routine options, go to the Alexa app. Try creating a routine that plays a News Briefing when motion is detected in the morning and a custom greeting that Alexa will say when you come home at night. Create a routine that will send an Alexa app notification when motion is detected. If you have a Smart Light or Smart Switch, use a Routine to automatically turn the light or switch on when you walk into a room and turn it off if there’s been no motion for a while.

### ⭐⭐⭐⭐⭐ Review
*by P***O on 1 December 2025*

This is a very good little motion sensor Im using with Home Assistant to switch on and off a light in the downstairs bathroom. It connected to my Zigbee hub instantly and has worked flawlessly since I installed it. Simple, small and long battery life (obviously depending on how often its triggered).
