event script e os.sleep

[Frank68]

Hello
I am trying with an event-based script when the value of a byte changes, to send mail, the byte can have value 0,1,2 my problem ache inside the script I should delay sending the mail for a time and re-read the value, as it takes time to pass between the various values, I tried with os.sleep () and to read the value after the time but it doesn't work, is there another way to do this function?

thanks a lot

Are you using event.getvalue()? You should use grp.getvalue(event.dst) after sleep.

Hi

I use grp.getvalue(event.dst) this is my code

Code:

-- INDICAZIONI COMUNI
-- get current data as table
now = os.date('*t')
TS=' del '..now.day..'/'..now.month..'/'..now.year..' alle '..now.hour..':'..now.min..':'..now.sec..'.'

-- recupero indirizzo mail e telefono principali
DestGen  = grp.getvalue('32/1/1')
NumTel  = grp.getvalue('32/1/2')

-- INDIRIZZI MAIL SECONDARI
DestMail1  = grp.getvalue('32/1/10')
DestMail2  = grp.getvalue('32/1/11')
DestMail3  = grp.getvalue('32/1/12')
DestMail4  = grp.getvalue('32/1/13')
DestMail5  = grp.getvalue('32/1/14')
DestMail6  = grp.getvalue('32/1/15')

-- NUMERI TELEFONO SECONDARI
NumTel1  = grp.getvalue('32/1/20')
NumTel2  = grp.getvalue('32/1/21')
NumTel3  = grp.getvalue('32/1/22')
NumTel4  = grp.getvalue('32/1/23')
NumTel5  = grp.getvalue('32/1/24')
NumTel6  = grp.getvalue('32/1/25')

-- recupero tag per destinazione
FLT_TAG1 = grp.getvalue('32/1/30')
FLT_TAG2 = grp.getvalue('32/1/31')
FLT_TAG3 = grp.getvalue('32/1/32')
FLT_TAG4 = grp.getvalue('32/1/33')
FLT_TAG5 = grp.getvalue('32/1/34')
FLT_TAG6 = grp.getvalue('32/1/35')

id=event.dst
-- wait forseconds
os.sleep(15)
--recupero  STATO INTERUTTORE
value = grp.getvalue(id)
-- recupero descrizione
name = grp.alias(id)
------- retry TAGS for mailing dest
tbl = grp.gettags(name)
strTAGS = table.concat(tbl, ', ')
-- last val memory
OldVal=grp.getvalue('32/1/55')
-- setc current val to OldVal object
grp.write('32/1/55', value)
-- cambio del valore rispetto giro precedente
if(value~=OldVal) then
--casistica valori
  if (value==1) then
    log('valore 1')
    subject = 'Commutazione selettore UTI'
    message = 'Stato  ID  - '.. id .. ' - ' .. name  ..'  Posizione 1  ' .. TS
    mail(DestGen, subject, message)

    alert(message)
    ALM = false
  end
    
  if (value ==2) then
    log('valore 2')
    subject = 'Commutazione selettore UTI'
    message = 'Stato  ID  - '.. id .. ' - ' .. name  ..'  Posizione 2  ' .. TS
    mail(Dest1, subject, message)

    alert(message)
    ALM = false
    end
    
  if (value ==0) then
    subject = 'Commutazione selettore UTI'
    message = 'Stato  ID  - '.. id .. ' - ' .. name  ..'  Posizione Sconosiuta  ' .. TS
    mail(Dest1, subject, message)
    log( 'valoer 0')

    alert(message)
    ALM = true
    end
end

------------------------------------------------------------------------------------

in my code I would like, if possible, that only after a certain period, depending on the value 0,1,2, delel actions were performed, but unfortunately seeing from the log ('value n'), 0 is always also executed without taking into account the time 15 cesondi, in this period the value has changed state and is no longer 0, in practice only if I have 0 after a certain period I have to perform an action.

available for clarification

thanks

You have this check: if(value~=OldVal) then but you say you want to execute a certain action only when a value has not changed in the past 15 seconds.
I think an event script is not a ideal solution here because each value change will trigger another script. How often does this value change? You can try a resident script that checks the object value every second and resets/increases a timer variable depending whether the value has changed or not.
