Resident script pump circulation - Domoticatorino - 07.03.2018

Hi,
I did a resident script that every minute checks the status of 2 valves and when one of them goes ON, a pump has to be start after 5 minutes.

Instead if valves are both OFF pump has to be stop immediately.

Considering that I have to use a os.sleep() command, I would like to avoid to run many script in parallel.

What do you suggest?

Thanks.

yHi,

Resident scripts don’t run in parallel, only event based do that.

BR,

Erwin

Do you mean that if script starts every minute and inside it there's a os.sleep() of 5 minutes, the second script doesn't start? Thanks

Scripts never block each other. You can safely use os.sleep in resident scripts. Though for larger delays I recommend using scheduled scripts.

RE: Resident script pump circulation - Domoticatorino - 08.03.2018

Hi Admin,
You're right but I cannot use a scheduled script. Otherwise I risk to want 10 minutes before starting the pump.
I need to don't run a script if the previous one is running. What do you suggest??
Thanks.

1. Add tag valve to your valve objects. Create an event script that is mapped to valve tag:

Code:
-- get OR'ed value of all tagged objects

value = false

objects = grp.tag('valve')

for _, object in ipairs(objects) do

  value = value or object.value

end

if value then

  -- save pump timer if timer has not been started yet

  time = storage.get('pump_on_time', 0)

  if time == 0 then

    storage.set('pump_on_time', os.time())

  end

else

  -- turn pump off

  storage.set('pump_on_time', 0)

  grp.checkwrite('pump', false)

end

2. Create either a resident script with large sleep time or a scheduled script that runs every minute:

Code:
-- turn pump on when time delta >= 5 minutes

time = storage.get('pump_on_time', 0)

if time > 0 then

  delta = os.time() - time

  if delta >= 5 * 60 then

    grp.checkwrite('pump', true)

  end

else

  grp.checkwrite('pump', false)

end

In both scripts replace pump with pump object name or group address.

RE: Resident script pump circulation - Domoticatorino - 08.03.2018

Code:
-- check if previous script needs to be killed

script_pompa_circolazione_notte = 'Pompa_circolazione_notte' 

pompa_notte_pid = storage.get(script_pompa_circolazione_notte)  

if pompa_notte_pid == nil then 

    pompa_notte_pid_os = os.getpid()

    storage.set(script_pompa_circolazione_notte, pompa_notte_pid_os)

else

    pompa_notte_pid_os = os.getpid()   

    storage.set(script_pompa_circolazione_notte, pompa_notte_pid_os)  

    os.kill(pompa_notte_pid, signal.SIGKILL) 

end

-- put here your script with os.sleep

Valvola_zona_notte = grp.getvalue('2/0/106')

os.sleep(0.5)

Valvola_bagno_zona_notte = grp.getvalue('2/0/105')

if Valvola_zona_notte or Valvola_bagno_zona_notte == true then

    os.sleep(360) -- attendi 360 secondi poi avvia la pompa di zona

grp.write('2/0/3', true)

else

  grp.write('2/0/3', false)

end

-- end of your scrript

-- clean up storage

storage.delete(script_pompa_circolazione_notte)

Surfing on the forum I found an instruction to avoid to add running script. Here above what I did.

It seems working. What I would like to do is kill the os.sleep time (360 seconds) if in the meanwhile logic OR is false.

I hope I have been cleared.

Thanks.

RE: Resident script pump circulation - admin - 09.03.2018

You script is not fully correct. Each telegram sent to valve objects will reset wait timer. In some egde cases pump can never be turned on.

RE: Resident script pump circulation - Domoticatorino - 09.03.2018

Hi Admin, you,'re right. In fact this morning pump did not srart. Can you suggest me how to update the script?
Thanks.

RE: Resident script pump circulation - buuuudzik - 09.03.2018

You can do it also as resident and use tag 'circulation_pump' for valves:

Code:
valveStatesTag = 'circulation_pump'

pumpGA = '1/1/10'

opened, first_timestamp = false, 0

valveStates = grp.tag(valveStatesTag)

for v = 1, #valveStates, 1 do

  valveState = valveStates[v]

  if valveState.value then

    opened = true

    if first_timestamp > 0 then

        if first_timestamp > valveState.updatetime then first_timestamp = valveState.updatetime end

    else

        first_timestamp = valveState.updatetime

    end

  end

end

if opened then

    opened_5_minutes = (os.microtime() - first_timestamp) >= 600

    if opened_5_minutes then

        grp.checkwrite(pumpGA, true)

    else

        grp.checkwrite(pumpGA, false)

    end

else

    grp.checkwrite(pumpGA, false)

end

RE: Resident script pump circulation - Domoticatorino - 09.03.2018

Thank you. Which resident time do you suggest?

RE: Resident script pump circulation - buuuudzik - 09.03.2018

For such think I like use 1 minute interval but if you want better reaction you can set less time like 30 or 15s oryou can adjust further this script e.g. you can choose Resident 0s and create auto adjusting the time for next calculation like below:

Code:
valveStatesTag = 'circulation_pump'

pumpGA = '1/1/10'

opened, first_timestamp = false, 0

valveStates = grp.tag(valveStatesTag)

for v = 1, #valveStates, 1 do

  valveState = valveStates[v]

  if valveState.value then

    opened = true

    if first_timestamp > 0 then

        if first_timestamp > valveState.updatetime then first_timestamp = valveState.updatetime end

    else

        first_timestamp = valveState.updatetime

    end

  end

end

if opened then

    opened_5_minutes = (os.microtime() - first_timestamp) >= 300

    if opened_5_minutes then

        grp.checkwrite(pumpGA, true)

        nextCalculationAfter = 30

    else

        grp.checkwrite(pumpGA, false)

        nextCalculationAfter = 301 - (os.microtime() - first_timestamp) -- run a little after possible change

    end

else

    grp.checkwrite(pumpGA, false)

    nextCalculationAfter = 301

end

log('Next calculation after: ' .. nextCalculationAfter .. 's.')

os.sleep(nextCalculationAfter)

You can also disable this script if heating controller is off.

RE: Resident script pump circulation - Domoticatorino - 10.03.2018

Cool, in which way I can disable the script?

Thanks

By use such command:

Code:
script.disable(script_name)

RE: Resident script pump circulation - Domoticatorino - 10.03.2018

Obviously in a different script?

Yes, but you can also take all script in 1 if statement and check the status of controller. Enjoy?

RE: Resident script pump circulation - Domoticatorino - 10.03.2018

Code:
valveStatesTag = 'pompa_circolazione_giorno'

pumpGA = '2/0/1'

opened, first_timestamp = false, 0

valveStates = grp.tag(valveStatesTag)

for v = 1, #valveStates, 1 do

  valveState = valveStates[v]

  if valveState.value then

    opened = true

    if first_timestamp > 0 then

        if first_timestamp > valveState.updatetime then first_timestamp = valveState.updatetime end

    else

        first_timestamp = valveState.updatetime

    end

  end

end

if opened then

    opened_5_minutes = (os.microtime() - first_timestamp) >= 120

    if opened_5_minutes then

        grp.checkwrite(pumpGA, true)

    else

        grp.checkwrite(pumpGA, false)

    end

else

    grp.checkwrite(pumpGA, false)

end

Hi, I use this script above and it seems does not work. I use 120 sec to check without loosing too time. Unfortunately Pump does not start.
What do you think?
Thanks.

RE: Resident script pump circulation - buuuudzik - 10.03.2018

Please check the updated version.

RE: Resident script pump circulation - Domoticatorino - 10.03.2018

It is a Schneider HL 2.0.1

I mean updated version of above script Wink

I've adjusted it to be more universal, added new variables:

Code:
valveStatesTag = 'circulation_pump'

pumpGA = '1/1/10'

openingValveTime = 300 -- time for fully open the valve (maximum time for next calculation)

minInterval = 30 -- minimum offset for next calculation

opened, firstTimestamp = false, 0

valveStates = grp.tag(valveStatesTag)

for v = 1, #valveStates, 1 do

  valveState = valveStates[v]

  if valveState.value then

    opened = true

    if firstTimestamp > 0 then

        if firstTimestamp > valveState.updatetime then firstTimestamp = valveState.updatetime end

    else

        firstTimestamp = valveState.updatetime

    end

  end

end

if opened then

    fullyOpened = (os.microtime() - firstTimestamp) >= openingValveTime

    if fullyOpened then

        grp.checkwrite(pumpGA, true)

        nextCalculationAfter = minInterval

    else

        grp.checkwrite(pumpGA, false)

        nextCalculationAfter = openingValveTime + 1 - (os.microtime() - firstTimestamp) -- run a little after possible change

    end

else

    grp.checkwrite(pumpGA, false)

    nextCalculationAfter = openingValveTime + 1

end

log('Next calculation after: ' .. nextCalculationAfter .. 's.')

os.sleep(nextCalculationAfter)
