What Is the Motion Sensor R1 and What Does It Do?
The Motion Sensor R1 from ThirdReality is a battery-powered Zigbee motion sensor that uses mmWave radar technology for detecting human movement. It solves issues with traditional PIR sensors by avoiding false triggers from heat or sunlight, providing reliable detection up to 9.5 meters with adjustable sensitivity via physical buttons. Commonly used for home security, energy-saving automations like light control, and notifications, it runs on three AA batteries for up to three years of operation. The device measures 65x65x30mm and requires no wiring, allowing flexible placement on shelves or walls.
What Does the Motion Sensor R1 Work With? (Compatibility and Integrations)
The Motion Sensor R1 requires a Zigbee 3.0 hub for operation and offers direct native integration with Zigbee hubs like Echo (4th Gen), Echo Plus, Echo Studio, Echo Show 8 (3rd Gen), Echo Show 10, Echo Hub, Eero 6, Eero Pro 6, SmartThings (2015/2018), Aeotec, Hubitat, Homey Bridge, Homey Pro, and Third Reality Hub Gen2 Plus. Ecosystems like Apple HomeKit and Google Home require the separate Smart Bridge MZ1 for indirect integration, while Amazon Alexa needs a smart speaker. It operates locally over Zigbee with no cloud dependency once paired, but setup involves pairing mode via button hold. Limitations include manual sensitivity adjustment only and no native Wi-Fi or Bluetooth support.
Does the Motion Sensor R1 Work With Home Assistant?
Yes, the Motion Sensor R1 works with Home Assistant via the ZHA or Zigbee2MQTT integrations, requiring a Zigbee coordinator stick. Both integrations operate locally, exposing motion detection, battery level, voltage, and link quality entities; Zigbee2MQTT also shows occupancy and supports OTA updates with recent versions (2.2.0-1 or later). Typical functionality includes binary motion sensors for automations, though cooldown time adjustment is via developer console in Zigbee2MQTT. It does not support static presence reliably despite mmWave tech.
