How can I create monthly changing energy tariffs for my variable energy contract


I’m struggling to keep my Energy dashboard up-to-date with the current prices.
Every 15th of the month my energy provider e-mails me the prices for the next month.
How can I pre-provision these prices in entities so they are enabled at the right time?
I’ve been searching the forum’s but haven’t found a solution that fits. Any help is highly appreciated!


my provider changes every month the current price, how can we do that?
