Delay script

[KoBra]

Resident script with 0 sleep time. Single script can be used for multiple timers by adding more entries to the timers table at the top of the script.

Code:

if not client then
  timers = {
    ['1/1/1'] = {
      output = '1/1/2', -- binary output
      delayon = 10, -- on delay time (seconds)
      delayoff = 0, -- off delay time (seconds)
    }
  }

  grp.sender = 'tm'

  client = require('localbus').new(0.1)
  client:sethandler('groupwrite', function(event)
    local timer = timers[ event.dst ]
   
    if timer and event.sender ~= grp.sender then
      local value = tonumber(event.datahex, 16) or 0
      local state = value > 0 and 'on' or 'off'
     
      if timer.state ~= state then
        timer.state = state
        timer.ticks = timer['delay' .. state]
      end
    end
  end)
end

client:loop(1)

for _, timer in pairs(timers) do
  if timer.ticks then
    timer.ticks = timer.ticks - 1

    if timer.ticks == 0 then
      grp.checkwrite(timer.output, timer.state == 'on')

      timer.state = nil
      timer.ticks = nil
    end
  end
end

I use the script above when the input becomes 1 the output becomes 1 10 seconds later. If the input becomes 0 the output stays 1 not going back to 0. What is the problem?
