I would be very grateful if someone could give me an example on how “set relative dim-level” works. I have a light switch with the option to “long-press” and would like to use it to dim the lights gradually. If I understand the function correctly, relative dim-level is what I need? Or if someone has a better option that’s fine too. Thanks ---

Check out this recent thread:[Relatief dim niveau](https://community.homey.app/t/relatief-dim-niveau/10955/2) Its in dutch, but goole might help you translate. It also shows example flows. ---

So I’ve understood how it works according to the previous messages but for some reason it only works once, what might I be doing wrong? If I turn my light off it’s “shining” at 0% correct? So if I choose relative dim level 20%, it should shine 20% brighter than 0. So far so good. Now if I run the same flow again, I assumed it should change from 20% to 40%, however this does not happen, it keeps shining at 20%. I know I have chosen relative dim-level because if I manually dim a light to let’s say 50% and run the flow, it goes to 70%. But if I run the flow again, nothing happens. Any idea? ---

Just tested this. With another trigger or with the test button like Roy stated it works like a charm. Can u try another trigger or, like @RoyWissenburg mentioned, try the test button to see what happens? ---

I just tried “dim to” and set it to 20% and its actually not as bright as when usin relative dim to 20% from zero…so I guess that’s where the issue is… No difference if I press the test button… ---

In Holland we say: Meten is weten. Like “not as bright” can mean a lot of things. ---

Well basically if I turn the light off and then use relative dim 20%,the light dims to about 80%.whereas if I use basic “dim to” and 20%, the light actually dims to 20% which is a lot less bright than 80% ---

Same behavior. It’s the relative dim that refuses to work in my flow… It just dims to the same value every time and stays there… ---

Interesting. I tried what you said. If I use the dim to value first and set it to 20% and after that I use the relative dim and set it to whatever like 10% it works, both with the physical button and the test button. However if I turn the light off and press the relative dim it goes all the way to about 80% so its only from when the light is off that it doesn’t work. ---

Got it, I will fix my flow accordingly 😊 Thanks for the help! ---

Are you using LEDs? LEDs are hard to dim at the lower %, It is related to very low load they have (thats why fibaro has a bypass in case you use leds) (“This Dimmer Bypass makes it possible to dim light sources with minimum power consumption, such as e.g. single 0,5Watt LED”) I have 4 philips led spots connected to the same dimmer. When I switch it on absolute to 15%, 2 of the leds go on, 2 just stay off. When I switch it on absolute to 20%, 2 of the leds go on, 2 sometimes go on right away, sometimes it takes a few seconds and then they pop on too. My advice: test your flows at higher dim %, if it works fine lower the percentage. ---

Yeah maybe you’re right, Its similar to my ikea spots, I have 8 of them and they behsve very randomly as well. Thanks for the tips I’ll test it out!
