Outdoor AirQuality Monitor
Know the air pollution levels, in near real-time, at many locations in the world.
Add one or multiple virtual outdoor air quality monitors to Homey. The information is made available free of charge by a number of services. Depending on the service and station you select, the following parameters are provided:
- O3 (Ozone)
- SO2 (sulfur dioxide)
- NO2 (nitrogen dioxide)
- CO (carbon monoxide)
- BC (black carbon, only available with OpenAQ in certain countries)
Air Quality Monitor Device setup
When adding a device, you can choose which service provider to use. Deciding on which service to use depends on your personal preferences, and mostly if the the service has monitoring stations nearby. Check the different coverages for your own location in the maps below.
By default the virtual monitor will be ‘installed’ at the location of your Homey. If you choose the @Homey station, Homey will always search the nearest source of data. If you select any of the other discovered stations, Homey will always use that particular station as data source. If you want to add a station anywhere else in the world, just add a local station first, and change the lat/lon in the device settings.
This free service provides government and research grade sources in over 60 countries. This service provides the easiest setup. Data is usually updated every hour.
This service provides government and research grade sources in over 90 countries. It has better coverage then OpenAQ, but it needs an API key. You can get a free API key here.
Luftdaten is dedicated to fine dust measurement with the Citizen Science project luftdaten.info. Thousands of citizens around the world installed self-built sensors on the outside their home. The data is limited to only show PM2.5 and PM10, but has a very high update rate up to once every minute.
Manually changing device settings
After adding a new monitor device, you can change the device settings.
Creating a flow
You can trigger a flow on every change in value:
The measured data is available as token cards:
