Delay script

[admin]

Create user library named timers:

Code:

return function(timers)
  if not client then
    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
end

Resident script:

Code:

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

require('user.timers')(timers)
