Airthings monitors track indoor air quality including radon, CO2, humidity, and VOCs. This guide covers common setup and accuracy issues.
Device Won't Connect
Pairing and connectivity issues:
- Bluetooth range: Stay within 10 feet of device during setup
- Hub required: Wave devices need Airthings Hub for WiFi/cloud - View Plus has built-in WiFi
- Fresh batteries: Most Wave devices use AA batteries - ensure they're fresh
- App permissions: Grant Bluetooth and location permissions to Airthings app
- Reset: Remove batteries for 30 seconds to reset Bluetooth pairing
Readings Seem Inaccurate
Sensor calibration and accuracy:
- Warm-up period: Radon sensors need 7 days for accurate long-term readings
- CO2 calibration: CO2 sensors auto-calibrate - need exposure to fresh air periodically
- Placement: Keep away from windows, vents, and direct sunlight
- Height: Mount at breathing height (3-6 feet) for relevant readings
- VOC baseline: VOC sensors establish baseline over time - readings improve
Radon Readings Fluctuating
Understanding radon measurements:
- Normal variation: Radon naturally fluctuates daily and seasonally
- Long-term average: Focus on weekly/monthly average, not hourly
- Ventilation: Opening windows temporarily lowers readings
- Weather: Air pressure changes affect radon levels
- Baseline: Initial readings stabilize after first week
Hub Connection Issues
For Airthings Hub users:
- 2.4GHz WiFi: Hub only connects to 2.4GHz networks
- LED status: Solid green = connected, blinking = trying to connect
- Device range: Hub communicates with devices via SmartLink radio
- Multiple devices: One hub can connect multiple Wave devices
- Placement: Central location for best coverage to all devices
Smart Home Integration
Connecting to other platforms:
- IFTTT: Connect Airthings to IFTTT for automations
- Home Assistant: Use official Airthings integration with API credentials
- Alexa: View readings via Alexa skill
- Google Home: Limited integration available
- Webhooks: Pro subscription enables webhook notifications
