Get prices from webpage via Excel

[Jørn]

Code:

now = os.date('*t')
pickhour = (now.hour + 1)

require('json')
require('ssl.https')

res = ssl.https.request('https://www.nordpoolgroup.com/api/marketdata/page/23?currency=NOK')
values = {}

if res then
 res = json.pdecode(res)

 if type(res) == 'table' then
   for _, row in ipairs(res.data.Rows) do
     cols = row.Columns
     value = cols[ 1 ].Value:gsub(',', '.')
     values[ #values + 1 ] = tonumber(value)
   end
 end
end

log(values[pickhour])

This seems to work, run it as a scheduled script 1 minute over every hour.
But with the current link in there, it looks like it's getting prices for the next day`?
