Price calculation is wrong when using a template. Time shift?

[MrOzzOnline]

Some taxes changed so I added the Entso-e sensor again with a new config. I noticed the following:

If I don't choose the option "I want to set VAT, template and calculation method (next step)" I'm getting te price without VAT or any additions. It's the exact price as listed in the entso-e website.

If I choose to use the template and set VAT to 0.0, I should get the same price. But I don't.

Configuration:

Results:

No template set (correct values):

Using the option to set VAT and template, but using 0.0 VAT and no template (incorrect values):

1. Please confirm you are using version Versie 0.7.1
2. Can you try/check the following:

• reconfigure the Item with template, where you set vat = 0
• I think you will find the period is set to PT60M.
  (Hypotesis: It looks like the period selected on the first screenshot is not correctly used/saved, and on the initial configuration (screenshot 2) where you can define the VAT and template you cannot configure the Period-->Period is set to the default of PT60M)
• Set it to PT15M, and submit
• Check if the values are now correct

I checked, double and triple checked it. I still see the error.
Version is 0.7.1

By the way, you cannot edit the sensor configuration if you've set it using the UI. You can't even see the used configuration.

I'm not fully sure we understand each other, so let me try again.
Go to http://<your_HA_hostname>/config/integrations/integration/entsoe

Locate the integration where you set a template. Now press the configure icon at the right side of it.
Here you can re-configure your configuration.
(That is why I don't understand your remark 'By the way, you cannot edit the sensor configuration if you've set it using the UI. You can't even see the used configuration.').

In this screen, what is the period currently set? I suspect it is set a PT60M.
Set it to PT15M, and press submit (at the bottom).

Next, locate the "No_template" item and press the configure item.
Check the period is set to the same value as you set in the item "with template" (so PT15M if you followed the previous instructions).
Press submit.

Both the template item and the no_template items should now have the same period set.
Now compare the prices of both integrations.
For me, both items now show the same prices.
(Before I changed the 'with template' item period from PT60M to PT15M they showed different prcies.)

I'm sorry I got confused with the Nordpool configuration - which you are unable to reconfigure.

Anyway, you are correct. The period was set to PT60M. Changing it fixed it.

But

When setting up a configuration for this integration you can choose PT15M or PT60M in the first screen and add a template in the second. The config seems to reset tot PT60M without notice.

Thanks for confirming the problem is fixed when you changed the period to PT15M.
Yes, agreed, there is a problem with the config flow for this integration. As far as I can see, the problem is that the period is not part of the 2nd screen, and not configured in that case.
