Is there an app with DAT (Day Ahead Temperature) values like the beautiful PbtH (Power By The Hour) has DAP (Day Ahead Pricing)?

The weather is not really good to expect. 😉

For the Netherlands you can look to this api.

> **[Weer API KNMI live en verwachtingen | Het Weer in Nederland - Weerlive.nl](https://weerlive.nl/delen.php)**
>
> Het weer in Nederland: temperatuur, windsnelheden en verwachting. Én de grafieken voor de komende 24 uur: hoe gaat het weer zich het komende etmaal ontwikkelen? Je leest het hier.

There is a demostation link with data form Amsterdam.

Hourly temp for the day and 5 days incl. today = (0)

_Back to topic for me._

If you’d like to use flows, you can use these flowcards (there’s several weather apps out there):

With [Insights Graphs](https://homey.app/en-nl/app/nl.mennovanhout.insights-graphs/Insights-Graphs/) you can create these kind of graphs  
Use a virtual cam device to have them showed in the device settings, or Homey Dashboard, like the price graph from PbtH:

Indeed I would like to use the max and min values for the next day in an Advanced Flow (in this case for my heat pump: why heating in the night if the next day is getting (very) warm?).

Especially in this period of the year you see rather cold nights but warm in the day (and even more warm due to the sun).

The KNMI flowcards, where do you see them? I can’t find the Homey Pro app.

Before I asked it in the PbtH-app I searched a lot. I got a ban for the off-topic message but luckely the system placed it back. I see so many off-topic messages, do they all get banned?

EDIT:  
It seems rather simple: just search for KNMI.  
I found 2 apps. At first glance they look rather identical to me. I’ll give it a try.

Cool!

Idk about posts being banned for being off-topic. Weren’t they just moved to an other or new topic?  
You can use the tag [@moderators](https://community.homey.app/groups/moderators) to ask what happened with a post, and or why.

You can use OpenWeather app. You can add a location for current weather and then add devices for forecasts (daily, hourly).

I received an email from the moderator explaning that at least one forum user has flagged my post. But they, after reading my post, unbanned my post (and moved it to a new thread which is ok).

Great!! This one doesn’t show up when searching …  
The search engine in the app shop is not very intuitive …

I’ll give it a try too. THANKS !!

Ah I see. “Banned” is not the word imho, the post gets temporary hidden until a mod has decided what happens next.  
Mods are volunteers and not (always) 24/7 available, sometimes it can take a while.

Just to be clear… For OpenWeather you need an API key with subscription (credit card), but 1000 calls free a day (ans you can set a limit). So safe to try.

It’s not the world’s finest 😬

A while ago I was advised we’re ought to use this link to the app search bar, because the search bar at the top is meant for articles and such. Little did I know… The bar at the top returns many apps, but not all.

 ![1000049156](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/2/42a57c5839b1061cbdbb5efbc2a4975923df1998.jpeg)

This one returns OpenWeather as well

For scandinavia below was easy to start with:  
[Weather Forecast from SMHI App for Homey | Homey](https://homey.app/en-fi/app/se.swefa/Weather-Forecast-from-SMHI/)

Still using it for simple staff (back-up for failing sensor), but…

When started to need up to 10 days FC, moved to raw-JSON source using web fetch from:

```auto
'https://api.spot-hinta.fi/PostalCodeTemperatures/' + postalCode + 'HomeAssistant=true';

```

where postalCode is e.g. (postal code itself has no meaning when coordinates given)

```auto
'00000?longitude=20.0000&latitude=60.00000&'

```

YR is another app option, to get a forecast x hours in the future.

For the Dutchmen here, there is a website ned.nl  
This site predicts the sun-power over a week ahead.  
The information is available for everyone using an API.

Interesting …

Edit: there is already a thread in this user forum about NED: ([Nationaal Energie Dashboard](https://community.homey.app/t/nationaal-energie-dashboard/126609?))

I can’t manage to get that info using the API. Do you have a way?

> Hoi Mark, Johan, Na het ‘tegenkomen’ van ned.nl vond ik dit topic. Nu heb ik het voor elkaar gekregen om gegevens zoals ‘type’ e.d. op te vragen via de [API handleiding](https://ned.nl/nl/handleiding-api). Dit scriptje hieronder zou hetzelfde moeten doen uit dat API voorbeeld, maar ja maar ja… Ik ben dus erg benieuwd hoe je bijv. de zonverwachting opvraagt. // API page: https://api.ned.nl/v1#/ // https://ned.nl/datacatalogus // https://ned.nl/nl/handleiding-api const myAPIKey = 'abc123'; // change into personal API key here …
