What Is the THIRDREALITY Motion Sensor and What Does It Do?
The THIRDREALITY Motion Sensor is a battery-powered Zigbee device designed for indoor motion detection. It solves the problem of manual activation for smart home routines by automatically detecting movement up to 30 feet away. Commonly used to trigger lights, alerts, or custom Alexa messages like “Welcome Home,” it supports pet-friendly detection to minimize false alarms from animals. Key hardware includes two AAA batteries lasting up to two years and simple wall mounting. Setup takes seconds via voice command on compatible hubs. It focuses on reliable, low-maintenance security and automation.
What Does the THIRDREALITY Motion Sensor Work With? (Compatibility and Integrations)
A Zigbee hub is always required for operation, with no direct Wi-Fi or standalone connectivity. Native integrations include Echo devices with built-in Zigbee hubs like Echo 4th Gen, Echo Plus, Echo Studio, Echo Show 8/10, Echo Hub, Eero 6/Pro 6, and Third Reality Hub Gen2 Plus. It works with SmartThings (2015/2018), Home Assistant, Aeotec, Hubitat, Homey Bridge/Pro via Zigbee bridges. Indirect support for Apple HomeKit, Google Home, and additional Alexa/SmartThings features requires the separate Smart Bridge MZ1. Voice control via Alexa enables routines for lights and notifications; local control depends on the hub, but cloud reliance occurs with Alexa. Limitations include indoor-only use and no native Matter or Z-Wave support.
Does the THIRDREALITY Motion Sensor Work With Home Assistant?
Yes, it works with Home Assistant via Zigbee integrations like ZHA or Zigbee2MQTT. It operates locally once paired to a compatible Zigbee coordinator. Exposed functionality includes binary motion sensor states, battery level, and link quality. No advanced features like adjustable sensitivity appear in standard integrations.
