    Automate your devices based on dynamic Nordpool electricity prices. 
    This blueprint automatically adapts to both hourly and 15-minute price intervals. 
    It calculates the true cost by allowing you to add custom grid fees for different time-of-use tariffs (e.g., day and night).
    Thank you @MikaelUlvesjo for inspiration, this is a re-work from your original blueprint.

    You can turn on devices during the cheapest periods by defining a total number of 'on' hours, setting a relative price percentage threshold, 
    or using an absolute low-price trigger. An 'always off' price threshold ensures devices stay off during the most expensive peaks.
