Template based on tomorrow's temperature

Configuration
1

Hello, I want to create a sensor to further use it in automation. I need to get tomorrow’s temperature and I am almost in the end with

  • platform: template
    sensors:
    forecast_tomorrow:
    friendly_name: “Tomorrow temperature”
    unit_of_measurement: ‘C’
    value_template: “{{ state_attr(‘weather.domov’, ‘temperature’) }}”

The only thing I need to obtain temperature from tomorrow (forecast: temperature). As you can see below. How to substitute “temperature” then?

You need to grab the forecast list, index into it, and grab the value of the temperature key:

{{ state_attr('weather.domov', 'forecast')[0].temperature }}

I have seen some changes in HA, looks like this method its not working anymore. Can someone explain where did i get wrong?

I have tried with the [0] also, same error.

You need to enclose the line with ".

value_template: "{{.....}}"

Not sure your .0. will work. I think it has to be as posted above in the thread.

It’s actually a standard way to index JSON (it’s the same as [0]). I did a quick test and it works in the template editor.

It’s #1 here: Templating - Home Assistant

I recommend checking out the others, too :slight_smile:

This has stopped working in 2024.4
Can’t figure out how to make a template with the newer weather service.

Any ideas/ suggestions?

where were you using it?

I created a template sensor in Yaml (although now it’s easier to do with helper)
It was like this :
“{{ state_attr(‘weather.home_gw’,‘forecast’).0.wind_speed }}”

It gave me the wind speed for tomorrow as a sensor. K had the same for tomorrow’s temperature. It was pretty convinent to have it. But now this doesn’t work anymore ? How can I create a template sensor now that shows me the value of tomorrow’s wind or temperature. ? Is it even possible with new changes ?

Thank you :slight_smile:

I had this as a TTS to give me the forecast for tomorrow in an evening report. Its not working now of course, how do I accomplish the same using the Weather: Get Forecasts service?

    Tomorrow, it is expected to be {{ state_attr("weather.home_2", "forecast")
    [1].temperature  }} and {{ state_attr("weather.home_2", "forecast")
    [1].condition  }}

awesome, Thanks.
Much simpler than I was thinking it was.

Hi! I would like to create an automation where every evening I get a notification if the temperature is forecasted to fall below a specific value (for example below the freezing point). Could someone please help me get started? I tried testing the script posted above in the template editor but I get an error stating: “None has no element 1”

I used this: “{{ state_attr(“weather.home.”, “forecast”) [1].temperature }}”
