Hello Guys I have a little problem, my aeotec nano dimmer wont dim, the only thing is on/off. It is connected to a dimmable led driver as the picture and that is connected on a led strip. Maybe it is a parameter or something, i exclude and include different times but nothing work also i dont notice the calibration wont start. So does anyone have a suggestion? Thanks for youre time again 😉 ![20210401_194356](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/b/dba6bea15865e4fbf9c2fe3f309cca2fbb6b9991.jpeg) ![20210401_194337](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/d/8ddd35ce19b0a9e5dac78d90e4ec98bfb00e436a.jpeg) ![20210401_194359](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/1/71e0607f2ec4c22d5f1f887bb2e39883ab829c02.jpeg) ![Screenshot_20210401-220123_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/8/78b979f58dc28523e3ac1d0c89ffb70c5b39b243.jpeg) ![Screenshot_20210401-220139_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/7/77b55d7cfbd9801dd298f0d61ed9f91a6cf97036.jpeg) ![Screenshot_20210401-215657_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/0/10e9dc266d5a9b397d972a5e8066f313387b8a55.jpeg) ![Screenshot_20210401-220145_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/5/f52931f0125e1b679443a8d7cb181529036c0df7.jpeg) ![Screenshot_20210401-220131_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/5/55d6289aea23054edfe5c8d660832265f3684fa7.jpeg) ---

Your led transformer can be dimmed by the (separated) 0-10 Volt DC input (the one on the right, with DIM on it), **not** by your 230V power (input) like the Aeotec nano dimmer does, even says it on the transformer itself “Dimming with:”. ---

I think it can baceuse on my driver is the text Leading edge-trailing edge. The picture is the schematic of the driver. As far as my knowledge reaches it has to work, I am not sure if I have it right. ![-67912657627139732](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/b/3b91fc9dc1bf510c40a843905bc182b9f09de026.jpeg) ---

Then this is the first transformer i’ve seen that can do both dim on 0-10V and triac on the power input. Further I can’t find much information about this transformer at all, their own website has only a constant current one (for 230V), which doesn’t seem to be the same as you have which is constant voltage (12v only). ---

The manufacturer says it can do both. I tested the 0-10c with a battery and that works fine. ---

Now it works, it a bit buggy to setup. After hours of trying I switched the leading edge and trailing edge and again back to leading edge. Then I noticed that the lights are dimming but the led was not very bright. Then I changed the measurement off load to never when on switched on. And then I put the Max brightness to 30 and backup. En Tada it works. So I am glad that it works and @Caseda you learn that there is a driver with both options. Anyway thanks for youre time and comment.
