Energy calculation and data saving

[admin]

Looks good to me. It can also be done without the third script by adding this to the end of the second script that runs every hour at 59 minutes:

Code:

-- run only on the last hour of the day
hour = os.date('*t').hour
if hour == 23 then
  total = energia_autoconsumata + grp.getvalue('32/1/16')
  grp.write('32/1/16', total)
end
