A Homebridge plugin for Airthings air quality monitors via the Airthings Consumer API.
- Homebridge
- One or more supported Airthings air quality monitors
- At least one Airthings SmartLink Hub (Hub, View Plus, View Pollution, View Radon)
| Airthings Device | Serial Number |

Air Quality Sensors are supported and implemented using standard Apple-defined services. Air Quality in this plugin is a composite of Radon, Particulate Matter (PM2.5), Volatile Organic Compound (VOC), Carbon Dioxide (CO₂), and Humidity sensors, depending on the sensors supported by your device and your plugin configuration. Air Quality values (Good, Fair, Poor) are based on Airthings-defined thresholds for each sensor.
| Sensor | 🟢 Good | 🟠 Fair | 🔴 Poor |
|---|---|---|---|
| Radon | <100 Bq/m³ | ≥100 and <150 Bq/m³ | ≥150 Bq/m³ |
| Particulate Matter (PM2.5) | <10 μg/m³ | ≥10 and <25 μg/m³ | ≥25 μg/m³ |
| Volatile Organic Compounds (VOCs) | <250 ppb | ≥250 and <2000 ppb | ≥2000 ppb |
| Carbon Dioxide (CO₂) | <800 ppm | ≥800 and <1000 ppm | ≥1000 ppm |
| Humidity | ≥30 and <60 % | ≥25 and <30 % ≥60 and <70 % |
<25 % ≥70 % |
Notes:
- Radon measurements are not visible in the Apple Home app, but are visible within some third-party HomeKit apps, including Eve and Home+. See the below section for more details on Radon sensors.
- This plugin converts Volatile Organic Compound (VOC) measurements from ppb (units Airthings devices report) to µg/m³ (units expected by Apple HomeKit).
Radon Sensors are not natively supported by Apple HomeKit. However, by default, Radon is used as a factor in the Air Quality Sensor (see above).
This HomeBridge plugin optionally supports a Radon Sensor by implementing a Leak Sensor, which is a standard Apple-defined HomeKit service. To enable this, specify a value for the optional radonLeakThreshold configuration property. Note this value is in Bq/m³, not pCi/L. This will be the Leak Detected threshold for the sensor in HomeKit, which can be used for Notifications and within Automations. The Radon measurement itself will not be visible in the Apple Home app, but is visible within some third-party HomeKit apps, including Eve and Home+.
Air Pressure Sensors are implemented using a custom HomeKit service that is supported by some third-party HomeKit apps, including Eve and Home+. Air Pressure Sensors are not natively supported by Apple HomeKit and therefore not visible in the Apple Home app.
Carbon Dioxide Sensors are supported and implemented using standard Apple-defined services. The Carbon Dioxide Detected threshold is ≥1000 ppm by default and customizable via the co2DetectedThreshold configuration property.
Temperature & Humidity Sensors are supported and implemented using standard Apple-defined services.
