There is currently support for the following device types within Home Assistant: - Sensor - Weather You need an API key, it requires a [subscription](https://openweathermap.org/api/one-call-3). The subscription has a free tier with 1000 calls/day. Consider setting the limit on the OpenWeatherMap website to stay under the threshold where API usage incurs a cost. This is done in the [Billing plans](https://home.openweathermap.org/subscriptions) page, under "Calls per day". ## ⚠️ Important Deprecation Notice ### OpenWeatherMap API V2.5 Deprecation OpenWeatherMap API V2.5 will be closed on October 7th 2024. After this date, you will need to use API V3.0. To continue using the service: - Visit the OpenWeatherMap website and activate the One Call subscription. - During activation, you will be prompted for a credit card, but you will not be charged unless you exceed the free tier limits. - Configure your OWM integration to select mode `v3.0`. - Note: Subscription activation may take up to 2 hours. For more details, set limits on your usage to avoid charges at [OpenWeatherMap Subscriptions](https://home.openweathermap.org/subscriptions). {% important %} If you register an new API key with OpenWeatherMap, it will be activated automatically, this typically takes between 10 minutes and 2 hours after your successful registration. Keep in mind when configuring this integration, that you new API key might not be activated yet. Recent policy changes limit the API access for new registered users with a free plan, they should select the `hourly` mode. The other modes require a paid subscription plan. Invalid API-key errors might occur if your API key is used with the other modes. {% endimportant %} {% include integrations/config_flow.md %} | Parameter | Value | | :-------- | :-------------------------------------------------------- | | API Key | API Key from the website | | Name | Name of the integration | | Latitude | Latitude for weather forecast and sensor | | Longitude | Longitude for weather forecast and sensor | | Mode |
  • `v3.0` (new API version) with daily forecast for 8 days, and 1-hour steps for 48 hours
  • `v2.5` (deprecated One Call API version), same forcasts as `v3.0`
  • `current` (current weather data only, no forecast)
  • `forecast` (forecast only, in 3-hour steps for 5 days, no current weather data)
    • | | Language | Language for receiving data (only for `sensor`) | A `sensor` entity will be created for each supported condition. Their IDs will follow the format: `sensor._` Sensors provide data in the language that was selected when configuring the integration. {% note %} The Weather entity provides data only in English. Home Assistant automatically translates it to the language configured for the frontend. {% endnote %} ## Supported Weather Conditions ### Current Weather Conditions | Condition | Description | | :----------------------- | :-------------------------------------------------------------------------------------------------------------------------------- | | `cloud_coverage` | Cloudiness, %. | | `condition` | [Weather condition](https://developers.home-assistant.io/docs/core/entity/weather/#recommended-values-for-state-and-condition). | | `dew_point` | Atmospheric temperature below which water droplets begin to condense and dew can form, ºC. | | `feels_like_temperature` | Temperature accounting for the human perception of weather, ºC. | | `humidity` | Humidity, %. | | `precipitation_kind` | The kind of precipitation (Rain, Snow, Snow and Rain, None) for the last hour. | | `pressure` | Atmospheric pressure at sea level, hPa. | | `rain` | Rain precipitation, mm/h. | | `snow` | Snow precipitation, mm/h. | | `temperature` | Temperature, ºC. | | `uv_index` | UV Index. | | `visibility` | Average visibility, m. | | `weather` | A human-readable description of the [weather condition](https://openweathermap.org/weather-conditions#Weather-Condition-Codes-2). | | `weather_code` | ID of the [weather condition](https://openweathermap.org/weather-conditions#Weather-Condition-Codes-2). | | `wind_bearing` | Wind direction, degrees (meteorological). | | `wind_speed` | Wind speed, meter/sec. | Details about the API are available in the [OpenWeatherMap documentation](https://openweathermap.org/api). ## Action `openweathermap.get_minute_forecast` This action populates [response data](/docs/scripts/perform-actions#use-templates-to-handle-response-data) with a mapping of minute-by-minute precipitation forecasts (rain or snow) for the next hour. **Note:** Minute forecast is available only when the OWM integration mode is set to `v3.0`. The action will fail if the mode is set to `current`, `forecast`, or `v2.5`. ```yaml action: openweathermap.get_minute_forecast target: entity_id: - weather.openweathermap response_variable: weather_forecast ``` The response data field is a mapping of `forecast` fields. `forecast` is a list of 60 forecasted precipitation levels; one for each minute of the next hour: | Response data | Description | Example | | ---------------------- | ----------- | -------- | | `datetime` | The time of the forecasted conditions. | 2024-10-19T18:59:00+00:00 | | `precipitation` | The precipitation amount in mm/h. | 1.25 | ## Examples {% details "Example action response" %} ```yaml weather.openweathermap: forecast: - datetime: "2024-10-19T18:59:00+00:00" precipitation: 5.46 - datetime: "2024-10-19T19:00:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:01:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:02:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:03:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:04:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:05:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:06:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:07:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:08:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:09:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:10:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:11:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:12:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:13:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:14:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:15:00+00:00" precipitation: 5.62 - datetime: "2024-10-19T19:16:00+00:00" precipitation: 5.79 - datetime: "2024-10-19T19:17:00+00:00" precipitation: 5.96 - datetime: "2024-10-19T19:18:00+00:00" precipitation: 6.14 - datetime: "2024-10-19T19:19:00+00:00" precipitation: 6.31 - datetime: "2024-10-19T19:20:00+00:00" precipitation: 6.48 - datetime: "2024-10-19T19:21:00+00:00" precipitation: 6.68 - datetime: "2024-10-19T19:22:00+00:00" precipitation: 6.89 - datetime: "2024-10-19T19:23:00+00:00" precipitation: 7.09 - datetime: "2024-10-19T19:24:00+00:00" precipitation: 7.29 - datetime: "2024-10-19T19:25:00+00:00" precipitation: 7.49 - datetime: "2024-10-19T19:26:00+00:00" precipitation: 7.72 - datetime: "2024-10-19T19:27:00+00:00" precipitation: 7.95 - datetime: "2024-10-19T19:28:00+00:00" precipitation: 8.18 - datetime: "2024-10-19T19:29:00+00:00" precipitation: 8.42 - datetime: "2024-10-19T19:30:00+00:00" precipitation: 8.65 - datetime: "2024-10-19T19:31:00+00:00" precipitation: 8.65 - datetime: "2024-10-19T19:32:00+00:00" precipitation: 8.65 - datetime: "2024-10-19T19:33:00+00:00" precipitation: 8.65 - datetime: "2024-10-19T19:34:00+00:00" precipitation: 8.65 - datetime: "2024-10-19T19:35:00+00:00" precipitation: 8.65 - datetime: "2024-10-19T19:36:00+00:00" precipitation: 8.91 - datetime: "2024-10-19T19:37:00+00:00" precipitation: 9.18 - datetime: "2024-10-19T19:38:00+00:00" precipitation: 9.45 - datetime: "2024-10-19T19:39:00+00:00" precipitation: 9.72 - datetime: "2024-10-19T19:40:00+00:00" precipitation: 9.98 - datetime: "2024-10-19T19:41:00+00:00" precipitation: 10.29 - datetime: "2024-10-19T19:42:00+00:00" precipitation: 10.6 - datetime: "2024-10-19T19:43:00+00:00" precipitation: 10.91 - datetime: "2024-10-19T19:44:00+00:00" precipitation: 11.22 - datetime: "2024-10-19T19:45:00+00:00" precipitation: 11.53 - datetime: "2024-10-19T19:46:00+00:00" precipitation: 11.89 - datetime: "2024-10-19T19:47:00+00:00" precipitation: 12.24 - datetime: "2024-10-19T19:48:00+00:00" precipitation: 12.6 - datetime: "2024-10-19T19:49:00+00:00" precipitation: 12.96 - datetime: "2024-10-19T19:50:00+00:00" precipitation: 13.31 - datetime: "2024-10-19T19:51:00+00:00" precipitation: 13.31 - datetime: "2024-10-19T19:52:00+00:00" precipitation: 13.31 - datetime: "2024-10-19T19:53:00+00:00" precipitation: 13.31 - datetime: "2024-10-19T19:54:00+00:00" precipitation: 13.31 - datetime: "2024-10-19T19:55:00+00:00" precipitation: 13.31 - datetime: "2024-10-19T19:56:00+00:00" precipitation: 13.73 - datetime: "2024-10-19T19:57:00+00:00" precipitation: 14.14 - datetime: "2024-10-19T19:58:00+00:00" precipitation: 14.55 ``` {% enddetails %}
