Sensor.Community
luftdaten
The Sensor.Community integration brings readings from the Sensor.Community open data air quality network into Home Assistant. Sensor.Community (formerly known as luftdaten.info) is a global citizen science project that maps air quality and environmental data from thousands of do-it-yourself (DIY) sensor stations around the world.
In Apple Home through HomeKit Bridge
What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.
| Entity | Shows up as | Note |

What people report
Sensor.Community stations are read-only and fetched from the public cloud API every 10 minutes.

| Device | In Home Assistant | In Apple Home | What they said | Source |
|---|---|---|---|---|
| Sensor.Community (Luftdaten) station | Works Cloud | Read-only particulate and climate data from public API, 10 min pollingSaved copyLimitations: The integration is read-only and relies on data that Sensor.Community stations upload to the public API. If a station stops uploading, the sensors become unavailable. Each Sensor.Community station usually has separate sensor IDs per sensor type. To track particulate matter and temperature from the same station, set up the integration once per sensor ID. The 10-minute polling interval is fixed and matches the upload frequency of most stations. Polling more often does not give you fresher data.

| Luftdaten sensors | Partly works | Partly in Home No longer shown as air quality sensor without device_class pm25 | Needs pm25 device_class customize to appear as air qualitySaved copy… 0.83.0 or newer Last working Home Assistant release (if known): 0.82.1 Operating environment (Hass.io/Docker/Windows/etc.): Docker Component/platform: Luftdaten Description of problem: Before 0.83.0, Luftdaten sensors were exposed to HomeKit as air quality sensors. Problem-relevant `configuration.yaml` entries and (fill out even if it seems unimportant): Not applicable as config flow is used starting 0.83.0. Traceback (if applicable): Not applicable. Additional information: I've tried starting HomeKit with a delay, it doesn't help. Excerpt saved from GitHub on 2026-10-23. | Issue #20941 · 2019-02 |
