Hi peeps. There are two things I don’t understand here: 1. I’m expecting this flow to trigger when the light “Taklampe gangen” is turned on. I turned the light on via the homey app, but it does not trigger the flow. If I have used the “Turned on” card wrong, please advice on how it is supposed to work. 2. If i test the flow the light is not dimmed at the value in the given variable. If I remove the variable and enter a value it works fine. Also noticed now that the dim card things all my variabled are empty(they are not). ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/e/ce4c12f2766d8206e38b2352818c73c9e0ebd8ba.png) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/b/0be239d957b9f84677beb468711a09c32b7b07be.png) ---

I figured out why the dim variable don’t work(there’s a hint in the second screenshot I posted). It’s supposed to be a value between 0-1. I used a value between 0-100.
