Hi people, I hope this hasn’t been already answered in another topic. I m looking for a way to create a flow making slowly dimmer some connected mural lights in my lounge or some lights in my garden. As an exemple : - Is there any function or variable I can use to make a connected light cycle from 10% to 100%, then back, within 2mn per cycle or user set time ? - Is there any variable I can add to this flow to slightly vary the cycles time within 10% or a user set percentage ? Thank you by advance for any answer. Cedrick. ---

The chronograph app has cards that support that. Andy ---

Thanks a lot for this answer, Andy. I’m gonna work on this 🙂 By the way, I guess I can also you the Chronograph app to set some lights to gradually dimmer from 0 to 100 each time I switch them on? ---

Hi Cedrick, Something like this ? > [@The Flow Exchange(r) - Exchange Your Flows with Others!](https://community.homey.app/t/the-flow-exchange-r-exchange-your-flows-with-others/68981/47): > > When you want, say, a light / lights to gradually dim up/down to a certain level over a longer period of time. > Like a wake-up light, or sleep-in light. > > ![Screenshot from 2022-12-19 05-08-03](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/c/0cdd8f692b8b0e929a302d80af2744945b21fa78.png) The dim-time range can be from seconds to days, very flexible. ---

My pleasure. It"s important to know the dim range in flowcards is 0 to 1 Like, 0.15 stands for 15%. And don’t use comma’s, only dots. ---

@Peter_Kawa Isn’t this standard in Homey these days? ![1000016354](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/1/8144c4ac90e021d7433ff26983800004c1c5b63a.jpeg) ---

Hi Tom, as far as I know this is only available for certain lights / apps, unfortunately it’s not a generic option. ---

Ah, okay. I didn’t know that.
