VMBDMI master+slave not behaving right

Hi VEL450

Yes, I am using 10.9.6
I only have one master dimmer in my project… this was the first time I have tried to use this feature.

I have figured out that the problem is to do with minimum dim values. Before setting up master slave I need to set minimum dim values for ALL lamps so that they behave the same.

The problems here arise from the other issue I reported here :-

https://forumtest.velbus.eu/t/vmbdmi-r-for-dim-value-is-not-same-range-as-for-minimum-dim/17187

With MIN DIM=0% my Lobby and Porch chandelier LED lamps start to operate at 60% dim. BUT the correct MIN DIM value is not 60%, it turns out to need 25%.
ie. MIN DIM=0% and my lamps illuminates from 60% to 100%
but MIN DIM=25% and my lamps illuminates from 1% to 100%

Similarly, with Aurora Mpro downlights
MIN DIM 0% and my lamps illuminate from approx 40 to 100%
but MIN DIM=12% gets me a good range form 1% to 100%.

So I have learned that it is important to set min DIM correctly for ALL lamps in a master/slave setup BEFORE trying to operate them together.

Most importantly the % used for MINIMUM DIM is NOT THE SAME as the % used in dimming. This makes it very difficult to setup… only by trial and error. I hope you can do something about this as it makes finding suitable minimum dim values quite difficult.

My velbuslink project file is attached FYI.
The Master in this case is US-LOBBY-Pendant (a chandlelier with several LED filament lamps)
The slaves are US-PORCH-Pendant (a smaller chandlier with same lamps)
and US-MainStair-DL, and Aurora MPro fire-rated downlight assembly.
