THIS IS THE NEW QUARTER-HOURLY VERSION This QuickApp calculates the cheapest prices for using appliances based on the hourly Tibber energy prices.  This QuickApp is especially useful for appliances (like charging your car and washing the dishes) that need to run once a day, within a timeframe and during some hours.  You can use more than one instance of this QuickApp if you need more than one appliance to start in the cheapest hour but not within the same timeslot.    IMPORTAN
