In Home Assistant 2024.4, this note was in the “Backward-incompatible changes” section of the release announcement
The previously deprecated
forecast
attribute of weather entities, has now been removed. Use theweather.get_forecasts
service to get the forecast data instead.

I had a heck of a time finding docs on this, so I have compiled what I did here.
Base weather integration
I am using the Tomorrow.io integration to get forecasts, but what I have done should work with any weather provider.
Current Conditions from Weather Station
I have made a custom weather entity that pulls current conditions from the weather station in my back yard and forecast data from the Tomorrow.io integration. The integration is known on my system as weather.tomorrow_io_leaky_cauldron_daily
.
Custom Sensors
To make this work, I first needed to make sure my configuration.yaml
contains this line:
template: !include templates.yaml
I then edited templates.yaml
and added this:
- trigger:
- platform: time_pattern
minutes: /15
action:
- service: weather.get_forecasts
data:
type: hourly
target:
entity_id: weather.tomorrow_io_leaky_cauldron_daily
response_variable: hourly
- service: weather.get_forecasts
data:
type: daily
target:
entity_id: weather.tomorrow_io_leaky_cauldron_daily
response_variable: daily
sensor:
- name: Weather Forecast Hourly
unique_id: weather_forecast_hourly
state: ""
attributes:
forecast: ""
- name: Weather Forecast Daily
unique_id: weather_forecast_daily
state: ""
attributes:
forecast: ""
This creates two sensors: one with the hourly forecast data and one with the daily forecast data.
Custom weather entity
Next, I needed to return to configuration.yaml
and add this:
weather:
- platform: template
name: "Home + Tomorrow.io"
unique_id: home_plus_forecast
condition_template: ""
temperature_template: ""
temperature_unit: "°F"
humidity_template: ""
attribution_template: "Home weather station + Tomorrow.io"
pressure_template: ""
pressure_unit: "inHg"
wind_speed_template: ""
wind_speed_unit: "mph"
wind_bearing_template: ""
forecast_hourly_template: ""
forecast_daily_template: ""
The parts of this that have weather.tomorrow_io_leaky_cauldron_daily
in them are pulled from the Tomorrow.io integration while the parts that start with sensor.outdoor_weather_station
are pulled from the Ecowitt integration that equates to my weather station.
The result of this is shown below:
