It might be that we’re talking about this issue to further our understanding of HomeyScript, for which I absolutely support that. However, if we’re concretely discussing how to relatively dim some lights based on input, it feels better to just use flow cards? ![relative dim](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/9/998d59768f088eba547f7e856174787f039e1925.png) ---

Hi Articate, In normal cases your card would probably be fine. Since this is about two plafonds with three lamps each my dimming ‘algorithm’ needs to do more than a simple fixed value dimming. The 20% I used was more of a testing value and not evident in my test code above. Good call though. ---

So you’re going to scale a max dim for each individual plafond or something? Like, that some plafond can go to 100%, but others only to 70%? and then if you dim 20% from 100% that’s 80%, but 20% from 70% would be 56% instead of 50%, is that what you want to achieve? ---

I need to experiment a bit to see where I will land with how the dimming algorithm will work in the end. Since each plafond has 3 ikea lamps there is lots of room for how to execute the dimming. In my last dimming step only one of the 3 lamps is lit 5% (ikea lamps turns off lower than that) and that is a perfect level for movie nights or similar where only a guide light is necessary. On the other hand the 3 lamps in the plafond at 100% each serves its purpose as well. Everything between those levels and number of lamps will take some time to figure out since I only want to deal with no more than 4-6 levels to work with. I have two of these plafonds in my living room but only one is ‘smart’ at the moment and since they each cover half of the room I want to come up with something smart in the end. I’m also considering replacing one of the lamps with its rgbw version to get a bit more variety at night. Time will tell… ---

Hi @Joka I just thought of the fact the [Papertrails](https://community.homey.app/t/app-pro-papertrails-log-advanced-logging-and-log-management-v0-6-3/40) app, can log time in ms; so no stopwatch or timestamp-script-cards are needed for measuring flowcards or scripts 🙃 ![Screenshot from 2022-07-14 16-27-36](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/0/20002de209c2b5ea5e41f5d9ae886d2b84988ead.png) . log: ```auto 2022-07-14 16:04.43.430 TurnLightOn start (script-monitor) 2022-07-14 16:04.43.937 TurnLightOn_FilterDevices - runtime (script-monitor ) 2022-07-14 16:04.45.053 TurnLightOn_LoopOverDevices - runtime (script-monitor ) ``` ---

That’s true but especially for this case I like to get a notification directly with the calculated runtime. [Previous page](https://community.homey.app/t/getting-the-device-by-its-id-takes-a-long-time/65621.md?page=1)
