Finde das war eine super Eselsbrücke.
Das vergisst man nie.

A correctly dimensioned driver solved the problem.
Thanks for the hint.

Thanks, I'll try.
The calculations helped ao lot understanding the issue.

Thanks fot the reply.
Did you try out all possible combinations of the dimming settings (e.g. leading vs. trailing edge, autodetect yes/no, running calibration) of the Shelly Dimmer 2?
Yes I tried every combination possible.
I hope you are using a real LED "driver" and not some (potentially old or reused) "transformer"? Exact make/model information and detailed technical specs of the new LED driver ("transformer") would be helpful.
I assume the new LED driver is also a constant current (CC) driver with 350 mA? Otherwise this is not expected to work. Especially constant voltage (CV) drivers will not work for your scenario.
Yes, I bought a dimmable constant current driver.
A bit oversized though.
pasted-from-clipboard.pngI attached 3 LEDs for the test (serial), so 9W.
So I can't see anything wrong.
The DALI thing confuses me, as I know, Hera can be controlled via DALI.
But shouldn't that matter?
It may well be the dimming from the original setup was DALI.
This is the controller that came with it:

I tried to use the "old" driver without the upper receiver.
But that didn't work either, this is stated here, nevertheless I tried:This is kinda frustrating.
Anybody has a constant current driver working with shelly dimmer 2?

Hi there,
I've got constant current LEDs
powered by this
and controlled and dimmed by this
The dimming with this system works flawlessly, but I want to control those LEDs with a shelly, to integrate them into the house system.
So I dumped the receiver and attached the transformer to the shelly.
LEDs blink all the time and calibration doesn't change anything.
So I bought another transformation, which was announced dimmable.
Same issue here.
Can anybody help me with this?
Thanks
