Prices not always updated after day change

[Floppe]

Version of the custom_component

0.0.7

Homeassistant version

2022.7.4

Describe the bug

Sometime when day changes then the prices are not updated. Have started to happen more frequent these days.

This is logged every hour until I restart HA and it starts to work again.

Debug log

2022-08-09 09:00:00 ERROR (MainThread) [homeassistant.util.logging] Exception in check_stuff when dispatching 'nordpool_update': ()

During handling of the above exception, another exception occurred:

Perhaps related to #127 ?

I've had the same problem for about a week. Tried to reinstall too but with no luck.

edit: Thinking that could be same issue as #125

Same problem here

At midnight, there are only (wrong) values ​​for the first hour for both days. The rest of the fields are empty. A restart of HA is required.

This is very likely closely related to https://github.com/custom-components/nordpool/issues/125 which has apparently been fixed in https://github.com/custom-components/nordpool/pull/127 almost half year ago but somehow that fix has still not been merged to master.

One approach could be just using https://github.com/custom-components/nordpool/tree/fix-1 branch until it gets merged.

Fixed for me in: Home Assistant 2022.10.1
