Contract start date

[Eric-AppSys]

Hey,

First off, thx for the excellent work!
I might be wrong, but when adding the integration, you can select the contract you have, but there's no startdate asked?
If this is added, you can get the correct prices for the contract as for now I think the latest contract price is calculated?
My contract is from nov 25, which is cheaper then the same contract name now.
Maybe also add the end date, so reminders can be pushed also via other automations?

Following up on this: the feature is implemented and ships in v0.10.0.

You were right that the integration priced every contract at the current card. It now accepts an optional contract start date, and prices your contract from there:

• Fixed and dynamic contracts are billed at the rate you locked in your signing month, for suppliers that keep an online archive of past cards (Bolt fix, Eneco, Mega). Only the commodity price is frozen to that month; the regulated network tariffs and taxes still track the current month, and the year-to-date cost re-bills each past month at your locked rate.
• Variable contracts whose card exposes a numeric index formula are re-priced by freezing your signing month's formula coefficients and re-applying them to the current month's mean, since a variable rate re-indexes monthly. This is exact for Cociter; for the RLP-indexed cards (EBEM, Eneco, Mega) the arithmetic monthly mean approximates the residential-load-profile weighting to within a few percent, which I have documented rather than hidden.
• For suppliers without an archive, or a start date older than the archive reaches, the setup flow offers an optional field to type the rate you signed at; leave it blank to keep using the current card.

There is also an optional contract end date, exposed as a timestamp sensor so you can build a renewal-reminder automation, exactly as you suggested.

Thanks for the well-reasoned report.
