Good evening I have installed a couple of Fibaro Dimmer 2 modules and I’m able to dim my lights when using a pushbutton. I use to group app to dim all my lights to 20% at a given time, this works fine if the lights are turned off and if I turn them on using the app or a pushbutton. (they are at the correct brightness) When the lights are already on, the brightness remains the same and does not go down. Is there a way to combine the 2 or should I create separate flows for this?

You can combine devices with the [\< group \>](https://homey.app/en-us/app/com.swttt.devicegroups/%3C-group-%3E/) app. ---

Hi @DirkG, thanks for your reply. I’m already using the \< group \> app and that is working fine but only when the lights are off, the lights don’t transition when they are on. ---

Sorry, I overread or misunderstood the words: > [@reyntjensw](#): > > I use to group app But then I don’t understand: > [@reyntjensw](#): > > Is there a way to combine the 2 or should I create separate flows for this? If I understand you correct, you want to change the brightness/dim level when the lights already turned on. And you want it by using the grouped devices? So this isn’t possible? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/2/22d802aac194a27793e7cd0ca0be9f201114f28d.jpeg) ---

Create a flow: ![Schermafbeelding 2021-06-10 om 09.29.36](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/2/020fa671b938027d59be9d5340473fbbd2068f1f.png) The “dim niveau” is of course the value of the dim level from the light that is being dimmed with the button (in the IF card). ---

Thanks for the examples, I managed to get everything working this way.
