Delay script

[admin]

Previous version did not handle zero timer values. Try this one instead:

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'

  function set(timer)
    grp.checkwrite(timer.output, timer.state == 'on')

    timer.state = nil
    timer.ticks = nil
  end

  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

        local ticks = timer['delay' .. state]
        
        if ticks > 0 then
          timer.ticks = ticks
        else
          set(timer)
        end
      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
      set(timer)
    end
  end
end
