dim up / down to percentage

[KoBra]

I run this script to change up/down dim to a percentage but when it runs the logic machine goes in overload (100%) Is there another/better way?

Code:

dimmer = grp.getvalue('1/3/10') step = bit.band(dimmer, 0x07) if step ~= 0 then   addr = '1/4/10'   up = bit.band(dimmer, 0x08) ~= 0   value = grp.getvalue(addr)   if up then     newvalue = value + 5   else     newvalue = value - 5   end   -- clamp between 0 and 100   newvalue = math.min(newvalue, 100)   newvalue = math.max(newvalue, 0)   if newvalue ~= value then     grp.write(addr, newvalue)   end end os.sleep(0.2)
