Airthings Wave monitors track radon, CO2, and air quality. This guide covers connectivity and accuracy issues.
Not Connecting to App
- Wave uses Bluetooth for phone sync
- Enable Bluetooth and location on phone
- Stand within 3 feet of device
- Wave in front of device to wake it
- Remove and re-pair in Airthings app
Hub Connection (Optional)
- Airthings Hub enables cloud sync
- Hub connects devices to WiFi/cloud
- Extend range with multiple hubs
- Hub required for continuous monitoring
- Without hub, manual sync via app needed
Radon Readings (Wave Plus)
- Radon sensor needs 7 days for accurate readings
- First readings may fluctuate significantly
- Place device in lowest lived-in level
- Avoid near windows, doors, or HVAC vents
- Radon varies daily - look at long-term average
CO2 Readings Seem Wrong
- CO2 sensor auto-calibrates over time
- Needs exposure to fresh air periodically
- Place away from people breathing directly
- Baseline is ~400 ppm outdoor air
- Indoor 1000+ ppm indicates poor ventilation
Home Assistant Integration
- Use Airthings BLE integration for direct connection
- Requires Bluetooth proxy (ESP32) for range
- Alternative: Airthings Cloud integration via API
- Cloud API has 5-minute update delay
- BLE provides near real-time updates
Battery Replacement
- Wave uses 2x AA batteries
- Wave Mini uses 3x AAA batteries
- Battery life is 1.5-2 years typical
- Low battery warning in app
- LED color indicates air quality (green/yellow/red)
