Timer - How to improve

[Fcs]

Hi everyone,

I'm using a script found on this forum, by Daniel, I believe, which I've modified a little to suit my needs. The only problem I'm having is that every time a READ passes on the bus, the updatetime value is updated, so my timer doesn't work as expected. Do you have any ideas? Thanks in advance

Code:

timers = {

  {
    name = 'TEST',
    input = '0/6/100',
    inputValueForTrigger = false,
    output = '14/0/202',
    outputValue = true,
    outputTimeMinutes = 6,
    writeInverseValue = true
  },

}


for _, timer in ipairs(timers) do     

  -- find required object
  obj = grp.find(timer.input)

  -- object exists and current state is "on"
  if obj and obj.data == timer.inputValueForTrigger then

    -- delta is in seconds   
    delta = os.time() - obj.updatetime
   
    -- switch when timer expires
    if delta >= timer.outputTimeMinutes * 60 then     
      grp.checkwrite(timer.output, timer.outputValue)
    end
   
  else
   
    if obj then
      if timer.writeInverseValue then
        grp.checkwrite(timer.output, not timer.outputValue)
      end
    end
   
  end
 
end
