Thank you for purchasing Skyen Optimize, and thank you for choosing a better indoor climate for yourself and your surroundings.
With SKYEN Optimize, you have 30 days of data storage and access to a dedicated dashboard where you can gain insights into your indoor climate data.
What is SKYEN?
SKYEN is ÅBN's indoor climate sensor, which measures your indoor climate and provides a quick overview at a glance.
What does SKYEN measure?
SKYEN records five important factors:
- CO₂
- Temperature
- Humidity
- Light level
- TVOC
- Sound level
What does the light mean?
SKYEN uses a discreet colored light to indicate the CO₂ level in the room:
- Blue light: CO₂ is below 1,000 ppm → the air is fresh.
- Red light: CO₂ is above 1,000 ppm → ventilate within approx. 30 min.
When CO₂ drops below 800 ppm, the light turns blue again.
After the device has been installed for 10-20 minutes, it will start sending data to the platform.
Step 1
- Open the camera on your phone or tablet
- Scan the QR code on your device
- Your dashboard will now open, and you can access your indoor climate data.
Step 2
The Indoor Climate Label:

The indoor climate affects our health, well-being, and concentration, but it can be difficult to assess its actual state.
ÅBN's indoor climate label makes it easy. It provides an overall rating from A (very good) to G (very poor), so you can quickly see how your indoor climate performs.
The blue letters (A → D) indicate a good indoor climate.
Red areas (E → G) should be improved, as they can affect health and well-being.
