trend export via csv

[PassivPluss]

hi
Earlier you had a example of how to export trends via ftp server as csv but now this doesnt work due to latest firmware.

Is it possible to get an working update for this?

require('socket.ftp')
require('genohm-scada.trends')

time = os.time()

date = {
  stime = time - 86400,
  etime = time,
}

values = trends.fetch('Effektforbruk lys', 'hour', date)

buffer = {}

count = 0
average = 0
resolution = 60 -- in minutes

row = string.format('%q,%q', "Tid", "Watt")
  table.insert(buffer, row)

for _, data in ipairs(values) do
  count = count + 1
  average = average + data[ 2 ]
  if count == resolution then
    date = os.date('%d.%b %H:%M', time -86400)
    value = average / resolution
    row = string.format('%q,%q', date, value)
    
    table.insert(buffer, row)

    time = time + 60 * resolution

    count = 0
    average = 0
  end
 
end
     
if #buffer > 0 then
  data = table.concat(buffer, '\n\r')
  res, err = socket.ftp.put({
    host = 'example.no',
    user = 'example@example.no',
    password = 'knfvkdnkd',
      argument = 'trend_dag_lys.csv',
      source = ltn12.source.string(data)
  })
end
