Event script that gets the target level and adjusts the output object in small steps. Adjust as needed:

Code:

output = '1/1/4'
step = 5
delay = 0.5

target = event.getvalue()
current = grp.getvalue(output)

if target == current then
  return
end

while true do
  if current < target then
    current = math.min(current + step, target)
  else
    current = math.max(current - step, target)
  end

  grp.write(output, current)

  -- stop when target is reached
  if current == target then
    return
  end

  os.sleep(delay)

  -- stop when targed changed, another script is running
  if grp.getvalue(event.dst) ~= target then
    return
  end
end
