Resident script pump circulation

[buuuudzik]

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.
