Home Assistant

Weather

The weather platforms gather meteorological information from web services and display the conditions and other details about the weather at the given location.

Building block integration

The weather integration cannot be directly used. You cannot create your own weather entities using this integration. This integration is a building block for other integrations to use, enabling them to create weather entities for you.

For a list of weather integrations, on the integrations page, select the weather category.

Home Assistant currently supports free web services some of which require registration.

State and state attributes

A weather entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service.
[Learn more]’s state is used to indicate the current overall conditions, e.g. ‘cloudy’ or ‘sunny’.

Condition mapping

The weather entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service.
[Learn more] can provide the conditions listed below as its state:

  • ‘clear-night’
  • ‘cloudy’
  • ‘fog’
  • ‘hail’
  • ‘lightning’
  • ‘lightning-rainy’
  • ‘partlycloudy’
  • ‘pouring’
  • ‘rainy’
  • ‘snowy’
  • ‘snowy-rainy’
  • ‘sunny’
  • ‘windy’
  • ‘windy-variant’
  • ‘exceptional’

State attributes

Detailed weather conditions as well as the unit of measurements used for the conditions are indicated by state attributes.

Service weather.get_forecast

Weather integrations which support weather forecasts expose the forecast using services. The services provided by weather entities are described below, and you can also read more about Service Calls.

Some integrations may not support the weather.get_forecast service, but instead expose weather forecasts as a state attribute named forecast. This behavior is deprecated and will be removed in a future release of Home Assistant Core.

This service populates Response Data with a weather forecast.

Service data attribute Optional Description Example
type no The type of forecast, must be one of daily, twice_daily or hourly. daily
