Getting information about air quality from Sensor Community

Note! The following instruction is dedicated for the second generation of HTTP Gate module (FW: 1.1.11-2218B)!

If we want to use information about air quality in the system, we may use an external service for this purpose e.g.: https://sensor.community

According to the example on the website: https://github.com/opendata-stuttgart/meta/wiki/EN-APIs, the API request might look like this: https://data.sensor.community/airrohr/v1/sensor/apiID/

where: apiID it is a sensor marking visible after selecting it on the map: https://maps.sensor.community/#3/40.00/15.00

Below we describe how you can easily obtain this information from two different sensors:

Create the HttpRequest virtual object:
Set the following parameters in the HttpRequest virtual object:

where:
Host: https://data.sensor.community
Path: /airrohr/v1/sensor/61982/

Create another HttpRequest virtual object and set its parameters as follows:

where:
Host: https://data.sensor.community
Path: /airrohr/v1/sensor/61983/
In the next step, create user features of the number type:

Then prepare a script called resp_dust:

if(Gate_HTTP->sensor_dust->StatusCode==200) then

  local resp = Gate_HTTP->sensor_dust->ResponseBody
  Gate_HTTP->PM10 = resp[1].sensordatavalues[1].value
  Gate_HTTP->PM2 = resp[1].sensordatavalues[2].value
  
end

Assign the script to the OnResponse event in the HttpRequest virtual object named sensor_dust:

Then prepare a script called resp_air:

if(Gate_HTTP->sensor_air->StatusCode==200) then

  local resp = Gate_HTTP->sensor_air->ResponseBody
  Gate_HTTP->sens_temp = resp[1].sensordatavalues[1].value
  Gate_HTTP->sens_pressure = resp[1].sensordatavalues[2].value/100
  Gate_HTTP->sens_humidity = resp[1].sensordatavalues[3].value
  
end

Assign the script to the OnResponse event in the HttpRequest virtual object named sensor_air:

Send the configuration to the CLU.

After sending the configuration, in both objects call the SendRequest method.

After calling the script, the StatusCode feature in both objects should get the value of 200.

User feature values should get the appropriate values:
For comparison - responses to requests sent via the browser:
The obtained data can be displayed in the mobile application, on the Smart Panel or used to create logic in the system.
