homebridge-airly-v2-nubzor

Homebridge plugin presenting information about air quality, temperature, humidity and pressure from Airly API.

By default measurement values are interpolated by averaging measurements from nearby sensors (up to 1,5km away from the given point). The returned value is a weighted average, with the weight inversely proportional to the distance from the sensor to the given point.

If you live outside of Poland or in case when the default approach to getting measurements won't work it's highly recommended to use nearest option to get measurements for an installation closest to a given location.

You can control the size of the area that will be scanned for the nearest installation by providing maxDistance (number, double, kilometers) in the config file.

However, if for some reason you want to get measurements from particular location you should provide locationId (number, integer) in the config file. You can obtain the locationId by going to the Airly Map. The easiest way to find the location's id is to select particular location, clicking on "Add widget to your site". At the bottom of the panel you can find "Generated code" section. You can find the location's id out there.

You shouldn't have nearest set to true and locationId at the same time as it may cause unexpected side effects.

Second (>= 2.00) version of the plugin works world-wide, please keep in mind that Airly coverage is slightly worse outside of Poland.

Instalation

1. Install Homebridge using: (sudo) npm install -g --unsafe-perm homebridge.
2. Install this plugin using: (sudo) npm install -g homebridge-airly-v2-nubzor.
3. Get API Key from Airly. Login here https://developer.airly.eu/login and generate it.
4. Decide on the how you want to get the data, following options are available
   • Default - Find out your coordinates (latitude and longitude). Based on that information Airly will show measurements from nearest sensor. You can use this page https://www.latlong.net/,
   • Nearest - First, follow the Default steps, then set nereast true and control maxDistance to get measurements from the closest device to your position,
   • From particular locationId - Find out the locationId, you can use the tips from the first section of README.
5. Update your configuration file like the example below.

This plugin is returning data such as: AQI (Air Quality Index), PM2.5, PM10, temperature, humidity and pressure.

Please, be advised that pressure is a custom characteristic which means it won't be present neither in Homebridge nor Home app. It's available in the apps which supports custom characteristics like Eve or Controller.

Configuration

Example config.json

"accessories": [
    {
          "accessory": "Air",
          "name": "Airly Air Quality",
          "apikey": "YOUR_API_KEY",
          "latitude": "YOUR_LATITUDE",
          "longitude": "YOUR_LONGITUDE",
          "nearest": false,
          "maxDistance": 5,
          "locationId": 0,
          "characteristics": {
            "PM25": true,
            "PM10": true,
            "temperature": true,
            "humidity": true,
            "pressure": true
          }
    }
]

Config file

Fields:

• accessory must be "Air" (required).
• name Is the name of accessory (required).
• apikey API key from Airly Developers (required).
• latitude String with your latitude e.g. "52.229676". Required for the default and nearest approach to obtaining measurements.
• longitude String with your longitude e.g. "21.012229". Required for the default and nearest approach to obtaining measurements.
• nearest Default false. Boolean (true/false) to change the approach to obtain measurements.
• maxDistance Default 5. Number (integer, value in kilometers). It controls the size of the area that will be scanned for installations. The closest one to your lat/lng will be choosen.
• locationId Default 0. Providing any positive number will turn on obtaining measurements through the location's id.
• characteristics an object that represents available characteristics (PM25, PM10, temperature. humidity and pressure). Use it to control which one you want to have present in the accessory. By default all are turned on.

Additional information

This project is based on Homebridge-airly-v2 made by andrzejf1994 it contains several improvements as the original project seems to be abandoned

Project is based on homebridge-airly and homebridge-weather and homebridge-arinow.

The difference between the base version is:

1. A valid npm package with works with Airly API v2 - as it doesn't work on Andrzej's version (issue)
2. Removed dependency on request library as it becomes deprecated - using built-in https module instead
