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
