What is the bug?

When using the popular DWD weather integration (German weather forecast - the prime forecast available here) there is no forecast.

https://github.com/hg1337/homeassistant-dwd

But the forecast data appears to be there - even hourly:

Steps to Reproduce

No response

Your Panel's YAML

Happy to provide additional information but so far I haven't seen anything unusual in the logs. :/

In your Home Assistant, could you please go to,Developer Tools, tab States, then filter by your weather entity and please.let me know what is displayed for both the column state but also the column attributes?
It's OK if you hide the sensitive info before sharing, I'm more interested in understand how the balões are provided than in the values itself. 😉

[andreas-bulling]

No problem - there is no sensitive information in here as far as I can see. The station is a general one for Stuttgart

Is this what you are looking for?

[andreas-bulling]

I found something in the HomeAssistant logs:

[edwardtfn]

Great. This is what I need.
I'm not at home right now, but will jump at this as soon as possible.

[andreas-bulling]

Suddenly it shows a forecast - but only for the next day. I didn't change anything - no idea why this is /(partly) working suddenly.

[andreas-bulling]

@edwardtfn Any update on this if I may ask?

[andreas-bulling]

Hi @edwardtfn - sorry to be a bit pushy but is there any update on this issue? It would be fantastic if DWD was supported - it's THE weather service people in Germany use. That is, adding support for it would potentially benefit a very large number of people. Thanks a lot!

[edwardtfn]

Unfortunately I've been totally out of time in the past weeks, but I will.look at this.

[yazz007]

@edwardtfn DWD sends null for uv_index sometimes, so you can avoid error by:

{{ states(accuweather_sensor_prefix ~ "uv_index" ~ accuweather_sensor_sufix) | default("unknown") 
   if accuweather 
   else (
      forecast_day | selectattr("uv_index", "defined") | rejectattr("uv_index", "eq", "") 
      | map(attribute="uv_index") | map("float", default=0) | list 
      | max | round(0) if (forecast_day | selectattr("uv_index", "defined") | rejectattr("uv_index", "eq", "") 
      | map(attribute="uv_index") | map("float", default=0) | list | count > 0) else 0
   )
}}

@andreas-bulling If you can't wait just edit the blueprint file located in: config/blueprints/automation/Blackmas/nspanel_blueprint.yaml:

uv_index: >
                                        {{
                                          states(accuweather_sensor_prefix ~ "uv_index" ~ accuweather_sensor_sufix, rounded=true) | default("unknown")
                                          if accuweather
                                          else
                                            (
                                              forecast_day
                                              | selectattr("uv_index", "defined")
                                              | rejectattr("uv_index", "eq", "")
                                              | map(attribute="uv_index")
                                              | map("float", default=0)
                                              | list
                                              | max
                                              | round(0)
                                              if
                                                forecast_day
                                                | selectattr("uv_index", "defined")
                                                | rejectattr("uv_index", "eq", "")
                                                | map(attribute="uv_index")
                                                | map("float", default=0)
                                                | list
                                                | count > 0
                                            )
                                        }}

and add default=0 to map("float") like above

NSPanel_HA_Blueprint/nspanel_blueprint.yaml

Line 10216 in 0c0be2d

| map("float")

NSPanel_HA_Blueprint/nspanel_blueprint.yaml

Line 10225 in 0c0be2d

| map("float")

[andreas-bulling]

Thanks a lot - will give it a try. I opened an issue for the integration as this needs fixing on their side.

[andreas-bulling]

Do you have a different version? I can't find the lines that you are referring to....

Keep looking for "uv_index"

[andreas-bulling]

This is what I have (already with the default=0)

uv_index: "{{\n  states(accuweather_sensor_prefix ~ \"uv_index\"
                      ~ accuweather_sensor_sufix, rounded=true) | default(\"unknown\")\n
                      \ if accuweather\n  else\n    (\n      forecast_day\n      |
                      selectattr(\"uv_index\", \"defined\")\n      | rejectattr(\"uv_index\",
                      \"eq\", \"\")\n      | map(attribute=\"uv_index\")\n      |
                      map(\"float\", default=0)\n      | list\n      | max\n      | round(0)\n
                      \     if\n        forecast_day\n        | selectattr(\"uv_index\",
                      \"defined\")\n        | rejectattr(\"uv_index\", \"eq\", \"\")\n
                      \       | map(attribute=\"uv_index\")\n        | map(\"float\", default=0)\n
                      \       | list\n        | count > 0\n    )\n}}\n"

But it still doesn't work.

[yazz007]

That is a bit strange, as it's not in repository. I guess you added it somehow ;-) You need to change something in automation to refresh display. It worked for me.

Sorry, I use this hacs addon: https://github.com/FL550/dwd_weather

[andreas-bulling]

What do you mean with "it's not in repository"? Which integration are you talking about?

I am using the same HACS DWD addon.

[andreas-bulling]

I had restarted the panel yesterday but without effect. Today, the panel suddenly started working, i.e. showing the forecast. No idea what has changed...
