Hourly weather forecasts no longer work after updating to Home Assistant 2023.8

[jaydeethree]

The problem

I have tested this with both custom components and core integrations, and it looks like Home Assistant 2023.8 broke hourly weather forecasts. Here's an example using the built-in National Weather Service integration - this is the entity that's created:

This entity contains a forecast for each hour. However Home Assistant is no longer able to display the hour for each forecast, it only displays the day:

And this is how it looks using the built-in weather card - again, hours are missing and only the day is displayed:

My best guess is that some part of this commit is the root cause, as it seems like that made significant changes to weather forecasting.

What version of Home Assistant Core has the issue?

core-2023.8.0

What was the last working version of Home Assistant Core?

core-2023.7.3

Hey there @home-assistant/core, mind taking a look at this issue as it has been labeled with an integration (weather) you are listed as a code owner for? Thanks!

Code owner commands

Code owners of `weather` can trigger bot actions by commenting: - `@home-assistant close` Closes the issue. - `@home-assistant rename Awesome new title` Renames the issue. - `@home-assistant reopen` Reopen the issue. - `@home-assistant unassign weather` Removes the current integration label and assignees on the issue, add the integration domain after the command.

Yep - tested with Pirate Weather and OpenWeatherMap, also multiple display cards, same on all.

I see this on all hourly weather forecasts, including OpenWeatherMap, National Weather Service and Weatherflow.

Confirmed it also happens with AEMET integration (https://www.home-assistant.io/integrations/aemet/)

Too maybe point in the right direction (or totally not) :) if I go into developer tools for the openweather entity and change the value of the first datetime entry to tomorrow (or somewhere in future it might) all values show up with a time again. so seems that after the update HA does not like it that the first found value is historical and forecasting??? No expert

Didn't make any difference for me. I found the first value was already at a future time, changed it anyway but still showing (Day) on the forecast card.

I think this issue is related with these: https://github.com/bremor/bureau_of_meteorology/issues/181 https://github.com/home-assistant/frontend/issues/17472

And, apparently they should be fixed with https://github.com/home-assistant/frontend/pull/17486 It will be included in frontend version 20230802.1 (https://github.com/home-assistant/frontend/releases/tag/20230802.1) expected to be included into 2023.8.3 (https://github.com/home-assistant/core/pull/98623) 🤞🤞

Confirmed, for me the update has resolved this issue and it displays hours again. Thanks!

It looks like the same issue, or a similar one has arisen after the update to 2024.4.0. When I check the service Weather: get.forecasts it shows today plus 5 days future forecast but when I run Get States for it, I only get today's forecast. Also, previous templates referencing forecast do not work.

@jlrosssc this was intentional: https://github.com/home-assistant/core/pull/110764 https://github.com/home-assistant/architecture/discussions/781

[jlrosssc]

I'm not clear how to now create this combined forecast showing hourly and daily. If I create Weather: Get forecasts service, and select daily or hourly, I get a daily or hourly forecast shown but neither shows when I select them in the States or reference in a card.

[hettinger77]

The 'Example template sensor that contains the hourly forecast' doesn't work for me using met.no. Forecasts were working and then broke recently. :-/

[MatthewFlamm]

I'm removing the nws label from this as multiple people have chimed in with other integrations and forecasts were changed in the built-in weather model.
