Calculate Daily, Monthly, and Yearly Energy from Trend

[Fahd]

Instead of making one script per trend you can use a single script for multiple trends:

Code:

mapping = {
  { trend = 'energy A', output = '0/0/1' },
  { trend = 'energy B', output = '0/0/2' },
  { trend = 'energy C', output = '0/0/3' },
}

require('trends')

dates = {}
dates['start'] = os.date('*t')
dates['end'] = os.date('*t')
dates['end'].day = dates['end'].day + 1

for _, map in ipairs(mapping) do
  sum = 0
  values = trends.fetch(map.trend, dates)

  for _, value in ipairs(values) do
    sum = sum + (value or 0)
  end

  grp.checkupdate(map.output, sum)
  os.sleep(1)
end

One trend per meter , so it will be 40
