Choose eMotion Pro if you want presence detection plus IR control in one room
eMotion Pro is the practical pick for rooms where people sit still, watch TV, work at a desk, or need AC/TV automation. It combines 24GHz mmWave presence sensing, WiFi + MQTT for Home Assistant, light sensing, and built-in IR control in one compact device.
| Need | Recommended LinknLink choice | Why it helps |
|---|---|---|
| Battery-powered placement | eMotion Air | Fast setup where wiring is hard. |
| One room with presence + IR appliances | eMotion Pro | Practical choice when one device should sense presence and control AC/TV scenes. |
| Higher-precision 60GHz sensing | eMotion Ultra | Choose when you want a premium multi-sensor room control path. |
Why eMotion Pro fits Home Assistant presence automation
eMotion Pro combines a 24GHz mmWave presence sensor, built-in IR emitter, light sensing, WiFi, and MQTT support in one compact device. It is designed for local Home Assistant workflows where presence can trigger lights, climate, media, and appliance control without adding a separate IR hub.
- Built-in IR emitter: control AC, TV, and other IR appliances from the same presence device.
- Direct WiFi + MQTT: connect to Home Assistant workflows without a required hub.
- 100% local control: keep automations private and responsive without cloud dependency.
The zone feature on eMotion Pro is designed primarily for easy indication, and zone detection may not always be highly precise. For more accurate zone-based detection and triggering, we recommend using our 60GHz presence sensors - eMotion Ultra.
Frequently Asked Questions
Choose eMotion Air for flexible battery placement, eMotion Pro for presence sensing plus IR room control, eMotion Ultra for higher precision 60GHz sensing, and eRemote HA for local IR control through Home Assistant MQTT.
Yes. eMotion Pro integrates with Home Assistant through MQTT workflows and the LinknLink local integration for presence-based automations.
eMotion Pro uses 24GHz mmWave radar with approximately 5-6m detection range and a wide coverage angle. Actual performance depends on room layout and placement.
No separate proprietary hub is required for the core Wi-Fi and MQTT automation path. It can be used with Home Assistant workflows for local control.
eMotion Pro can detect still presence more effectively than a basic PIR motion sensor, helping keep lights or scenes active while someone is sitting, reading or working.
Sensitivity can be tuned to reduce unwanted triggers from small pets. Results depend on room layout, pet size and placement.
