From what I see, the items are updated on start and after that every hour but not on the hour. This means that, when the first update (after restart) happens on hh:58, all other updates are done on :58. Therefor all the entsoe based items are 58 minutes behind.
if this is correct, @furieux’ question is legit. Maybe @gitMiguel elaborate on this (if he’s still onboard) ?
