Dimmer extension correction values don't behave as expected.

[Gast]

Default the Dimmer extension correction values are:
Input Value 1: 0
Target Value 1: 0
Input Value 2: 100
Target Value 2: 100

I'm using Philips Dimtone LED lights. As mentioned in my previous post the "leading-edge" setting is used to get them working stable.

Using the smartphone app I can now change the brightness of the LEDs. However the LEDs only start to light up at 40% en go to full brightness at 100% (as seen in the app).

To correct for this I did make the following changes in the correction values:
Input Value 1: 0
Target Value 1: 40
Input Value 2: 100
Target Value 2: 100

The behavior in using the app stays the same?

with that correction, your lamps will be getting 40% power when off in loxone - this is going to waste a lot of power

do you have the perception correction on? if so, it stretches out the usable dimming range so that there is finer control between 0-30% - if your lamps are not lit at this level, it leaves a lot less of the interface range to actually adjust the brightness which may be part of the problem

i know you swapped to leading edge, but most leds will dim over a much wider range when used with trailing edge.

as an experiment, try trailing edge with perception correction turned off, and see if the leds will come on at a lower % and have a smoother dimming range.

its frustrating to try to get leds that are:
1) compatible with the dimmer at all
2) wide range of dimming
3) dont flicker
4) have a decent light quality - high cri and high R9 for red output
