LUA help, how to get top 4 values?

[rovrell 0]

Hi!

I'm trying to control electrical load and divert load like heating the house during the time when the electricity is cheap.
I'm getting the pricedata in a textfile with the prices for each hour on a separate row (24 rows). Example:
500
510
520
530
540

 

I then want to analyze this data and be able to tell the LUA script that I want to stop running certain loads during this 4 most expensive hours for example.

I do not know how to write this code in LUA though. Could anyone point me in the right direction?

1) you can't upload a file to HC2

2) so, according to #1 you should have own http server for getting data in LUA scene in HC2

Thanks for quick reply!

I'll look a little bit more on Monday when I have some time;) I didn't think I would get such a quick response.

I will get the data from "https://elen.nu/timpriser-pa-el-for-elomrade-se3-stockholm" a friend of mine will fix an api for this site. As I will be able to read.

Yours sincerely, Robert

my code does not provide auth for the site. so. please provide what authorization used this site.  is it basic auth?

There is no authorization yet. The API is not created, will probably last a week before the buddy had time to fix it.

I attempted "wrapapi" just to test:
"Https://wrapapi.com/use/rovrell/nordpool/dygnspris/latest?wrapAPIKey=upgNUlLJVe1Q4OD4wjDCWg3wwWQJxIBp"

 

But will get the data better when he does it
