Send notification email after change value (delay)

1. Check that you have "Execute on group read" enabled. It might cause the script to run. Enabled logging for the mapped object to see where the value write or read comes from.

2. Set script "Execution mode" to "Last instance only" and use this code:

Code:

curr_value = event.getvalue()
prev_value = storage.get('prev_value')

if curr_value == prev_value then
  return
end

storage.set('prev_value', curr_value)

os.sleep(10)

if curr_value then
  subject = 'Main switch = ON'
  message = '\nState: Normal'
else
  subject = 'Main switch = OFF'
  message = '\nState: ALARM!!'
end

mail('1234@yyyyyyy.ww', subject, message)

1. I already disabled "Execute on group read". In "Object logs" it turns out that the signal from the controller (in this case a very old JUNG unit) is checked and the SL responds ("14/2/188 decoded value 1" and it hasn't changed), and after that script is running.
2. Thanks for the code - everything works. But I probably defined the problem inaccurately - the script should work ONLY if the value of the group has changed and remained for at least 10 seconds. (the script should not work if there is a fast switching ---> from 1 to 0 and back (within 3 sec for example).
Currently, the last value after switching is sent.
