Linknlink eMotion Ultra: The 60GHz All-in-One Presence Sensor Your Smart Home Needs
If you want the ultimate presence sensor for Home Assistant, the Linknlink eMotion Ultra stands out as the undisputed leader. It’s more than a presence radar: it’s a full control hub combining 60GHz mmWave radar, infrared (IR) control, environmental sensors and even a Bluetooth hub.

VideoWhy the eMotion Ultra Beats the Competition
Unlike traditional PIR sensors that miss you when you stay still, the eMotion Ultra uses 60GHz mmWave radar. That lets it detect even breathing, preventing lights from turning off while you read or watch TV.
Key Features:
- 60GHz Radar: Greater accuracy than 24GHz models.
- Multi-person Tracking: Able to track live movement of up to 4 people simultaneously.
- 2D Zone Map: Lets you define specific areas (sofa, desk, door) to trigger different automations depending on where you are.
- Infrared (IR) Control: Replaces your TV, air conditioner and audio remotes.
- Built-in Sensors: Light (lux), temperature and humidity.
Unboxing and First Impressions
The eMotion Ultra package is surprisingly complete. Besides the main unit with its handy magnetic mount, it includes:
- A wired external temperature and humidity sensor.
- An additional Bluetooth thermo-hygrometer (BLE) that pairs directly with the eMotion Ultra thanks to its Bluetooth hub.
Home Assistant Integration via MQTT
This is where the eMotion Ultra shines for advanced users. Unlike the "MAX" model, the Ultra enables full integration via MQTT.
In the video 📡 60GHz Presence Sensor + IR + Temperature and Humidity we walk through the process step by step:
- We enable MQTT mode in the Linknlink app.
- We configure our broker settings in Home Assistant.
- Done! You’ll have all entities (presence, 2D map, sensors and IR control) available locally with lightning-fast response.
IR Control: Automate the "Non-Smart"
One of the biggest perks is its ability to control infrared devices. You can add your TV or air conditioner and operate them directly from your Home Assistant dashboards, removing the need for other hubs like Broadlink.
eMotion Ultra vs. eMotion Pro: Which to Choose?
While both are excellent, the Ultra justifies its price by including the 60GHz radar (versus the Pro’s 24GHz) and offering greater processing power for person tracking and zone management. It’s the recommended choice if you want to avoid false negatives and have total control.
