This blueprint lets uses nordpool data to rank hours from cheapest to most expensive so you can select how many hours you want to count as cheap and you can in addition to that select where in the price span from cheapest(0%) to most expensive(100%) you count as cheap this way if you select that you want 12 hours of on time or below 50% of the price span as minimum the devices will be on for 12 hours but if the price is low most of the day but have a short peek price it may be enabled for more hours.
If you set start and end minutes to different values the devices will be on from start minute to end minute if the price is lower than Always off price that can be useful for when controlling heating that you want to run at least for a short time every hour to not let the temp drop to much if there is a long expensive period.
Parameters:
Start minute
Set the minute in hour to check if the price is low
End minute
If this is different than Start minute the turn on action will be performed by if price is lower than allways_off and on the end minute the turnoff action will be performed if expencive hour
Hours on
Set the minimum of hours per day that the devices should be on
Hour percent
Max percent between minimum and maximum price of the day to turn on devices
Always on price
if the price is below this the device is always on (ignoring Hours on and Hour percent)
Always off price
if the price is above this the device is always off (ignoring Hours on and Hour percent)

Be nice to me this is my first attempt at creating a blueprint 
, but sadly with time frame ( from 22.00pm to 6.00am light always should be off) blue print not working. Perhaps I don´t know how to setup properly.
