This is what ChatGPT has to say, but my question is how did you get ostrom to home assistant?:
The issue here seems to stem from the data_generator syntax. Specifically, there are some minor syntax errors in the JavaScript code, and the code structure could be adjusted to ensure the data_generator returns the values correctly in a format that ApexCharts expects.
Here’s a breakdown of what’s likely causing issues and a potential fix:
Issues
Incorrect syntax in entity.[index]: The extra dot (.) before [index] is incorrect. It should just be entity[index].
Possible issue with entity.map usage:map might not work as expected on entity if entity is not already an array of timestamps and values.
Solution
We’ll adjust the data_generator code to make sure it’s correctly mapping each value with the right timestamp.
Modified Code
Here’s the corrected data_generator code:
type: custom:apexcharts-card
graph_span: 25h
span:
offset: '-1h'
now:
show: true
label: Jetzt
all_series_config:
unit: cent
header:
show: true
show_states: true
colorize_states: true
title: Preis Forecast
series:
- entity: ostrom.price
data_generator: |
// Get the timestamp for the current hour and adjust based on index
const startTime = new Date().setMinutes(0, 0, 0);
return entity.map((value, index) => {
return [startTime + index * 3600000, value]; // Increment by hours in milliseconds
});
Explanation of Changes
Timestamp Calculation: We define startTime to be the beginning of the current hour using setMinutes(0, 0, 0).
Time Increment: We then increment the time for each value in the entity array by adding index * 3600000 milliseconds (1 hour in milliseconds).
Mapping Values: return [startTime + index * 3600000, value]; associates each value with the correct timestamp.
Additional Notes
Make sure that:
ostrom.price is returning an array of values as expected.
The formatting within the data_generator aligns with ApexCharts’ requirements for data points (array format with [timestamp, value]).
This should help resolve the issue and display the forecast data correctly in the apexcharts-card.
