doesn't always start and if it has started it fails after a while the log always writes

Unhandled exception. System.Collections.Generic.KeyNotFoundException: An index satisfying the predicate was not found in the collection. at Microsoft.FSharp.Collections.ArrayModule.loop@722-39[T](FSharpFunc2 predicate, T[] array, Int32 i) in D:\a\_work\1\s\src\fsharp\FSharp.Core\array.fs:line 723 at Microsoft.FSharp.Collections.ArrayModule.Find[T](FSharpFunc2 predicate, T[] array) in D:\a_work\1\s\src\fsharp\FSharp.Core\array.fs:line 725 at <StartupCode$EnergyAssistant>.$Program.main@() in /src/src/EnergyAssistant/Program.fs:line 224 /run.sh: line 4: 78 Aborted (core dumped) dotnet exec EnergyAssistant.dll /data/options.json

hope the message makes sense

think it's after an update of home assistant

I have updated to version 0.66. Today was a mess, data wise as EnergiDataService was down and carnot.dk was testing the new algorithm.

There is some robustness lacking from the code (result of 1 hour here and there programming on it) - but if it fails for me, I do fix it as I rely on it to keep my electricity costs down.

The update has added a isPrediction field to the hourPrices, allowing for better confidence in the numbers.

If you are using ApexChart, you can change the data_generator to return [new Date(start["hour"]).getTime(), entity.attributes.prices[index]["isPrediction"] ? 0 : entity.attributes.prices[index]["price"]]; to show only the confirmed prices from EnergiDataService (public API for accessing Nord Pool data legally).

Please reopen, if you issue persists - I will take a look, just not until later this week.

I am now seeing your problem. Hold for a few more minutes.

To get HA to see the update as soon as possible, you need to open the Store (blue button, bottom right on the add-ons page), then click the three dots up right and search for updates.

Will post, when it is fixed in mine, at least.

V0.67 is working on mine.

I need to add some failure handling, such as when energidataservice.dk is down.

However, today I added a failover to Nordpool, when Energidataservice is down, which seems to be the case every other weekend. Hopefully that keeps working, until I get around to a bit more extensive refactoring and stabilization.

Just to be clear:

• Carnot.dk data forms the basis
• Energidataservice.dk spotprices are used to replace data from Carnot.dk, where available
• If Energidataservice.dk returns no result, then Nordpool data is fetched directly for the current day only
