Kaku dimmer in smaller steps

[mlafeber]

Hi, I have about 10 Kaku dimmers in my house with an RFXCOM. Recently I switched to LED bulbs which have a smaller dimmer range. I can't get the dimmer steps down by 1% or logarithmic. I've checked the internet for some solutions, but I could not get it working. Is there anybody with a suggestion? Thanks in advance!

KAKU dimmers have 15 fixed steps, so steps of 6.66%
