Luftdaten.info local API sensors

There is an sensor for HASS called luftdaten, it queries the cloud based API and creates sensors in HASS.
The air quality open source sensor project is based upon a NodeMCU (ESP8266) and a SDS011 particle sensor.

You can if you want query the your local ESP8266 instead of the cloud API.

Access the local sensor is done via HTTP and the output is JSON. http://ip.adress/data.json is the URL to query.

More info can also be found (in german) on www.luftdaten.info and Swedish on www.luftdata.se

While you are technically correct, why not contribute to the Luftdaten info and register your sensor at their platform?

Done both, of course … Sorry for not being clear on that.

Love crowd sourced such as this one! <3

In the meantime I have built my own Luftdaten sensor, and have experimented with different ways of integrating this into HA without making a detour through the cloud, and decided to go with InfluxDB instead of rest.

If you are interested in reading more about this, take a look here:

Little late to answer but thanks for the tip! I was getting fed up with data not being fetched from the Luftdaten website, somehow the PM10 and PM2.5 rarely went through.

I would like to fetch sensor data as well but my sensor (data) is not available in hassio and also have error with “This entity does not have a unique ID” Can someone provide updated config in yaml please?
My JSON

{"software_version": "NRZ-2020-133", "age":"118", "sensordatavalues":[{"value_type":"SDS_P1","value":"37.28"},{"value_type":"SDS_P2","value":"13.68"},{"value_type":"BME280_temperature","value":"4.74"},{"value_type":"BME280_pressure","value":"99404.13"},{"value_type":"BME280_humidity","value":"86.27"},{"value_type":"samples","value":"5017387"},{"value_type":"min_micro","value":"28"},{"value_type":"max_micro","value":"20570"},{"value_type":"interval","value":"145000"},{"value_type":"signal","value":"-74"}]}

Hi,

This is exactly what I am looking for, locally polling and retrieving the Lufdaten sensor data. As I am new to HA and have no programming skills I need a bit of help.
My temperature sensor is a BME280 so also does air pressure.
How do I add the air pressure to the code? Just copy and paste and then update to:

  - platform: command_line
    name: "Luftdata Air pressure BME280"
    command: 'curl http://192.168.x.x/data.json'
    value_template: "{{ value_json.sensordatavalues[4}.value | round(2) }}"
    unit_of_measurement: hPa"

Then the big question is where do I place this YAML code? In /homeassistant/configuration.yaml or do I need to make a file (lufdaten.yaml) and place it somewhere?

Thanks for pointing me in the right direction. really appreciated :slight_smile:

Bernard

Please do not put the same question in two places. This thread is very old (6 years to be exact), and most likely the example no longer works. Look here for more recent examples how to get the data:
