Heatwave-Ready Room Automation with eMotion Ultra
eMotion Ultra combines 60GHz mmWave presence sensing, a temperature and humidity sensor cable, and built-in IR control. In Home Assistant, this lets one room device support presence-aware cooling, comfort monitoring, and local AC or fan commands.
- Presence: keep cooling active when someone is seated or still.
- Temperature and humidity: react to real comfort conditions instead of fixed schedules.
- Built-in IR: control AC, TV, fans, and other IR appliances from local room scenes.
eMotion Ultra FAQ
Which LinknLink device should I choose for Home Assistant automation?
Choose eMotion Ultra for 60GHz room presence, temperature and humidity data, and built-in IR control; eMotion Pro for presence sensing plus fall-detection use cases; eMotion Air for flexible battery placement; and eRemote HA or TV Kit Pro when your main goal is IR remote control via Home Assistant MQTT.
What is eMotion Ultra used for?
eMotion Ultra is a 60GHz mmWave presence sensor for rooms where standard motion sensors can miss people who are sitting still. It combines presence sensing, zone detection, IR control, light sensing, temperature and humidity data, BLE hub functions, and MQTT workflows for Home Assistant. For buying comparisons, see our guide to best mmWave presence sensors for Home Assistant.
Does eMotion Ultra require a separate hub?
No proprietary hub is required for the core setup. eMotion Ultra connects through 2.4GHz Wi-Fi, while Home Assistant, MQTT, BLE accessory, and voice assistant workflows depend on the integrations and settings you choose. If you also need a dedicated IR bridge, compare it with eRemote HA.
How many detection zones can eMotion Ultra support?
eMotion Ultra supports up to 4 customizable detection zones in the app, such as a sofa, desk, bed, or walkway. Actual performance depends on placement, room layout, interference filtering, and the automation rules you configure.
What is the detection range of eMotion Ultra?
The recommended maximum detection range is up to 6m / 20ft for moving presence and about 4m / 13ft for stationary presence when the sensor is placed with a clear front-facing view of the room.
Can eMotion Ultra control a TV or air conditioner?
Yes. The built-in 360-degree IR blaster can send commands to many compatible IR appliances, including TVs, air conditioners, and audio devices. For TV-focused setups, consider TV Kit Pro; for broader IR automation, read the best IR blasters for Home Assistant guide.
Is eMotion Ultra compatible with Home Assistant via MQTT?
Yes. eMotion Ultra is compatible with Home Assistant via MQTT, including presence, zone, light, temperature, humidity, and IR-related entities for local automations.
Which BLE sensors and accessories can pair with eMotion Ultra?
eMotion Ultra can act as a BLE hub for compatible LinknLink accessories. Common add-ons include EDS2 door/window sensor, ETH2 temperature and humidity sensor, and the THS temperature and humidity cable.
Is eMotion Ultra battery powered?
No. eMotion Ultra is USB-C cable powered and should be used with a certified 5V/2A power adapter.
