The PIR Bottleneck in Home Assistant
We’ve all experienced the frustration of smart home automations failing due to traditional sensors. You’re sitting perfectly still reading a book, and the lights in your Home Assistant-managed room turn off because your PIR sensor thinks the room is empty. Or, even worse, the lights trigger erroneously because the sensor detected a shadow through a crack in the door.
Enter the 24GHz mmWave Radar
eMotion Air changes the game by utilizing 24GHz mmWave radar technology. Unlike PIR, which relies on large-scale movement, mmWave detects micro-vibrations—specifically, the rise and fall of a human chest while breathing. This means eMotion Air knows you are there, even if you are perfectly still.
Native MQTT for Local-First Speed
For the advanced Home Assistant user, speed and privacy are paramount. eMotion Air supports native MQTT, ensuring that presence data is streamed locally to your server with zero cloud dependency. This results in instant automation triggers—turning on lights the millisecond you enter, and holding them until you leave.
5-in-1 Data Stream
Beyond presence, eMotion Air provides critical environmental data points directly into Home Assistant:
-
Luminance (Lux): Perfect for zone-based lighting control.
-
Temperature & Humidity: Essential for smart HVAC management.
If you are looking to elevate your Home Assistant environment from basic automation to true smart intelligence, eMotion Air is the essential upgrade. Experience the precision of 24GHz radar and bring your home to life.
