Script help

[svetoslavp]

Modify as needed, make sure that step value is the same as script sleep time (at least 5 seconds, can be more if the wait time is larger).

Code:

temp = grp.getvalue('1/1/1')

-- temp limits
temp_low = 20
temp_high = 30

-- time in seconds
time_low = 20
time_high = 40

step = 5 -- script sleep time in seconds

if temp < temp_low then
  timer_high = nil

  if timer_low then
    if timer_low < time_low then
      timer_low = timer_low + step

      if timer_low >= time_low then
        grp.write('1/1/2', true)
      end
    end
  else
    timer_low = 0
  end
elseif temp > temp_high then
  timer_low = nil

  if timer_high then
    if timer_high < time_high then
      timer_high = timer_high + step

      if timer_high >= time_high then
        grp.write('1/1/2', false)
      end
    end
  else
    timer_high = 0
  end
end

Thank you very much!
