eMotion Ultra 60GHz mmWave Radar Presence Sensor - Precise Stationary

In this review of the eMotion Ultra, the bottom line is simple: this is a sensor for people who want far more than old PIR motion detectors. The eMotion Ultra uses a 60GHz mmWave radar to detect subtle stationary presence, including breathing and minimal movement, and combines that with brightness, temperature, humidity sensing and a 360-degree IR blaster. It is best for smart-home enthusiasts and Home Assistant users who want local MQTT integration, multi-zone tracking and an extensible BLE hub rather than a basic occupancy switch.

Key Features

• Stationary human detection: Detects very small motions such as breathing or heartbeat when facing the sensor, letting automations stay active while someone is sitting or sleeping.
• Anti-interference controls: App-configurable interference zones and height filtering remove false triggers from curtains, plants or pets for more reliable presence events.
• Multi-zone positioning: Draw up to four custom zones in the app and assign separate automations so a single device covers sofa, bed, desk and other areas.
• Local Home Assistant integration: Operates locally via MQTT so presence, brightness, temperature and humidity are available as entities for fast, private automations.
• Built-in IR and environmental sensors: A 360 IR blaster controls AV and climate gear up to about 15m and the on-cable sensor reports ambient light, temperature and humidity for contextual rules.
• BLE hub and cloud export: Acts as a BLE hub for up to 20 accessories and stores three years of cloud history with CSV export for review or analysis.

Who It's For

The eMotion Ultra suits smart-home tinkerers and users who value accurate, privacy-friendly presence detection and tight Home Assistant or MQTT control; its local operation is a major advantage for those who want low latency and offline capability. It is also useful for households where pets or moving objects trigger traditional PIR sensors, because the interference zone and height filtering help avoid false positives.

It is less appropriate for someone who needs a simple, battery-powered motion detector or a low-cost, single-purpose occupancy sensor; eMotion Ultra requires a certified 5V/2A power adapter and is intended as a mains-powered hub-style device with a bit more setup involved.

Pros & Cons

Pros

• Extremely sensitive stationary detection that senses micro-movements for reliable presence tracking.
• Flexible multi-zone setup and live tracking of up to four people without capturing images, preserving privacy.
• Local MQTT/Home Assistant support and BLE hub function make it extensible and suitable for advanced automations.
• Integrated IR blaster plus brightness, temperature and humidity sensing reduce the need for extra sensors.

Cons

• Requires a certified 5V/2A power adapter and mains power, so it is not ideal for battery-only installations.
• Detection range is limited compared with larger systems (max about 6m moving, 4m stationary), so placement planning matters.

Our Verdict

The eMotion Ultra is a strong choice for advanced smart-home users who want accurate stationary presence detection and local MQTT/Home Assistant control, bundled with an IR blaster and environmental sensing. It offers excellent value when you need privacy-friendly, multi-zone detection and BLE accessory support, provided you can power it from a certified 5V/2A adapter and plan placement within its range.

Frequently Asked Questions

Does it work with Home Assistant?
Yes. The device operates locally and exposes entities via MQTT for Home Assistant integration.

Can it ignore pets or curtains?
Yes. You can define interference zones and set height filtering in the app to reduce false triggers from pets or moving objects.

Is the IR blaster powerful enough for TVs and AC?
The built-in 360 IR blaster supports universal control up to about 15m and can control TVs, air conditioners and AV gear.
