I have 4 Philips dimmable led ligts and the fibaro bypass connected to one fibaro dimmer 2. I have calibrated the dimmer. For unknown reasons the dimmer can only dim in the lower part of its 100% range. At about dimming position 30% the lights are 100 lit. I have the dimmer connected to an up/down switch and N and L wired. The configuration works as expected except its non linear range. Any idea what this could be? ---

U might adjust the parameters in your dimmer settings in homey. If u calibrate it sets sometimes like 30% so you can adjust manually ---

Alex, this parameter is not available on the Fibaro. mvg Steef de Koning ---

[https://manuals.fibaro.com/document/fgd2-advanced-parameters/](https://manuals.fibaro.com/document/fgd2-advanced-parameters/) These parameters can be used in advanced settings -\> rough configuration parameters like this: 2,1,30 ---

Do you happen to know which parameter I have to change? Based on the descriptions I was not able to select the right parameter. mvg Steef de Koning ---

If you go on the settings inside homey on your dimmer 2 u can find the adjustment as u see on the top of my picture. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/6/461bf45f5b58fc755682f276747a23d9b2548d55.jpeg) ---

Thanks , I changed the brightness limits and indeed it is much better to control. mvg Steef de Koning
