Rather than relying on motion alone, the R3 senses micro-movements to tell if a person is actually present, and it communicates status through a programmable RGB ring while also reporting ambient light and TVOC data where supported. It connects via Zigbee 3.0 for broad smart-home compatibility and runs continuously from a USB-C power source.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the 60 GHz mmWave radar improve presence detection?\u003c\/h3\u003e\n\u003cp\u003eThe millimeter-wave radar detects tiny movements such as breathing and small posture shifts that traditional PIR sensors miss. This reduces false off events in quiet spaces and maintains lighting or automations while someone is stationary.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDetects micro-movements including breathing for true presence recognition.\u003c\/li\u003e\n\u003cli\u003eAdjustable detection distance to avoid false triggers from adjacent rooms.\u003c\/li\u003e\n\u003cli\u003eWorks reliably in darkness and through some non-metal barriers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat does the RGB light do and how can it be used?\u003c\/h3\u003e\n\u003cp\u003eThe integrated RGB ring provides visual cues for occupancy, automation states, or alerts, making system status visible at a glance. You can assign colors or brightness levels to different conditions, and the light will also flash for air-quality warnings if configured.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAmbient illumination and programmable status colors for quick room feedback.\u003c\/li\u003e\n\u003cli\u003eFlashing red when TVOC levels indicate poor air quality (platform dependent).\u003c\/li\u003e\n\u003cli\u003eUses light as a presence indicator so lights stay on while someone remains in the room.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich smart home platforms and devices is the R3 compatible with?\u003c\/h3\u003e\n\u003cp\u003eR3 uses Zigbee 3.0 and integrates with popular hubs and ecosystems including Home Assistant (ZHA \u0026amp; Z2M), SmartThings, and many Echo devices with built-in Zigbee. It also functions as a Zigbee repeater to strengthen your mesh network.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWorks with Home Assistant via ZHA and Zigbee2MQTT for local control.\u003c\/li\u003e\n\u003cli\u003eCompatible with SmartThings and Echo hubs (multiple generations).\u003c\/li\u003e\n\u003cli\u003eActs as a Zigbee repeater to improve network range and reliability.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat environmental data does the R3 provide and how reliable is it?\u003c\/h3\u003e\n\u003cp\u003eThe device reports ambient light (lux) and TVOC air-quality readings when the connected platform exposes those sensors. Availability of these readings and alert behaviors depends on the hub or software you use.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLux sensor supports automations based on room brightness.\u003c\/li\u003e\n\u003cli\u003eTVOC reporting enables simple air-quality alerts where supported.\u003c\/li\u003e\n\u003cli\u003eIndicator light can signal dangerous TVOC levels if your platform honors the alert.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe R3 is USB-C powered for continuous operation without batteries, making it suitable for always-on monitoring. It targets bedrooms, bathrooms, offices, and any quiet indoor space where presence must be detected reliably without motion triggers. Combined with Home Assistant, SmartThings, or Echo hubs, R3 is ideal for smarter, more human-aware automations that keep lights, HVAC, or privacy-related functions aligned with actual occupancy.\u003c\/p\u003e\n\n\u003cp\u003eWho this is for: Installers and smart-home enthusiasts who need accurate, always-on presence detection in quiet rooms; homeowners seeking stronger Zigbee mesh and straightforward visual status; and anyone wanting lux and TVOC sensor data to feed automations. The R3 is not a medical device but a home automation sensor best used to improve comfort, convenience, and energy efficiency where traditional motion sensors fail.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does R3 work with Home Assistant?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
