Never looked before but it seems that it should be possible - they have info here Publishing Air Quality Data: on the aqicn.org / waqi.info map
Hi,
I succesful send data to WAQI.
I use Home Assistant to do that.
I have the Airgradient firmware with the MQTT set up
I retreive the data in HA by setting a sensors in the config yaml file.
mqtt:
sensor:
- name: "AirGradient Outdoor"
state_topic: "airgradient/readings/<id of the AG>"
value_template: "{{ value_json.pm02 }}"
unit_of_measurement: "µg/m3"
json_attributes_topic: "airgradient/readings/<id of the AG>"
I use pm02 as main value cause, I can calculate US AQI after that (not provided in MQTT stream (could be a nice improvment))
→ It will create a sensors with PM02 as main value and all the other data are attributes to that sensors
Then I setup a node red flow inside Home Assistant to send data to WAQI via the json api
Here the code to import in Node Red (you can delete weather data as I send my Davis Vantage data)
You have to set your lat long in the function box and also your Token from WAQI (works like a charm)
→ You can remove Weatherlink box and AQI box too
