RoomSense IQ multi-zone presence detection mapping showing multiple tracked zones in a room.
Smart automation

mmWave radar and PIR sensors detect real presence — not just motion. RoomSense IQ knows when you're in the room, where you are, and what you're doing, so your home can respond intelligently without a single tap.

True privacy

RoomSense IQ processes all data locally on-device. No camera, no audio, no cloud dependency. Your presence data stays in your home and is never shared with third parties unless you explicitly choose to.

Works anywhere

Ceiling or wall mounted, RoomSense IQ covers up to 60 m² with configurable detection zones. One device handles an entire room — including tracking multiple people simultaneously with sub-zone precision.

Open ecosystem

Native Home Assistant integration via MQTT and BLE. Works with Alexa, HomeKit, and Google Home. No vendor lock-in — RoomSense IQ speaks the protocols your smart home already uses.

Smart Presence Detection

RoomSense IQ allows smart-home enthusiasts to automate household infrastructure based on their physical presence. It makes your heating, cooling, ventilation, lighting, entertainment, air-filtration, home-security, and emergency-alert technology — among other essential services — smarter, easier to manage, and more efficient. Create a truly harmonious living environment that knows where you are, and has a pretty good idea what you're up to, but does not share that information with a third party unless you tell it to. You remain in control without having to manage so many…controls.

SightSense web-based dashboard

Introducing SightSense, our Web-Based Dashboard

SightSense is a web application that adds a whole new layer to the RoomSense IQ ecosystem — giving you an intuitive interface to manage all your sensors. Unlike platforms that are too complex or too limited, SightSense offers both basic and advanced configuration options.

Features include CalSense for baseline calibration, MoveSense for movement classification, ProxiSense for proximity-based automation, and BedSense for sleep optimization. All together, these give you exceptional control over the spaces you inhabit.

RoomSense IQ Home Assistant MQTT integration

Works with Your Existing Smart-Home Ecosystem

RoomSense IQ is fully compatible with Home Assistant's MQTT auto-discovery protocol, giving you flexibility, customization, and support for a wide range of devices through the world's most popular open-source smart-home platform.

RoomSense IQ also plays well with Amazon Alexa, Apple HomeKit, and Google Home through IFTTT. Multi-zone deployment is fully supported — monitor multiple rooms from a single dashboard.
