If you're fine with having timer resolution in minutes not seconds, this should work:

Code:

mintimer = 1 -- minimum timer value in minutes
maxtimer = 30 -- maximum timer value in minutes

objects = {
  {
    output = '1/1/1',
    timer = '2/1/1',
  },
  {
    output = '1/1/2',
    timer = '2/1/2',
  },
  {
    output = '1/1/3',
    timer = '2/1/3',
  }
}

function dosleep(obj)
  local timer = grp.getvalue(obj)
  timer = tonumber(timer)

  if timer then
    if timer < mintimer then
      timer = mintimer
    elseif timer > maxtimer then
      timer = maxtimer
    end

    sleep(timer * 60) -- minutes -> seconds
  end
end

for _, item in ipairs(objects) do
  grp.write(item.output, true)
  dosleep(item.timer)
  grp.write(item.output, false)
end
