dim up / down to percentage

[admin]

Use an event script with execution mode set to "Last instance only".

Code:

out = '32/0/25'

dimmer = event.getvalue()
step = bit.band(dimmer, 0x07)

if step == 0 then
  return
end

up = bit.band(dimmer, 0x08) ~= 0

vstep = up and 5 or -5
value = grp.getvalue(out)

while true do
  nvalue = value + vstep
  nvalue = math.min(nvalue, 100)
  nvalue = math.max(nvalue, 0)

  if nvalue ~= value then
    grp.write(out, nvalue)
    value = nvalue

    os.sleep(0.2)
  else
    break
  end
end

What do you mean by everything gets slow? The script sends 5 telegrams per second which is not a high load. You can lower this by increasing the sleep time. You might need to adjust the step size to keep the dimming speed the same as before.
