# OpenWeatherMap Input Plugin

Collect current weather and forecast data from OpenWeatherMap.

To use this plugin you will need an [api key][] (app_id).

City identifiers can be found in the [city list][]. Alternately you can
[search][] by name; the `city_id` can be found as the last digits of the URL:
https://openweathermap.org/city/2643743

### Configuration

```toml
[[inputs.openweathermap]]
  ## OpenWeatherMap API key.
  app_id = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

  ## City ID's to collect weather data from.
  city_id = ["5391959"]

  ## APIs to fetch; can contain "weather" or "forecast".
  fetch = ["weather", "forecast"]

  ## OpenWeatherMap base URL
  # base_url = "https://api.openweathermap.org/"

  ## Timeout for HTTP response.
  # response_timeout = "5s"

  ## Preferred unit system for temperature and wind speed. Can be one of
  ## "metric", "imperial", or "standard".
  # units = "metric"

  ## Query interval; OpenWeatherMap weather data is updated every 10
  ## minutes.
  interval = "10m"
```
