I have upgraded my homey to v2. Rc4 but now my din rail dimmer start at 100%. Even when my flow is putting them on dim 20% as worked before the upgrade. I tried the qubino beta version and removed all dimmers and installed them again but no changes in the start. The light is so bright on starting up now I need to wear my sunglasses :)🕶 . Any thoughts ? ---

Definitely I have thoughts, send an issue to athom 😉 [https://support.athom.com/hc/requests/new](https://support.athom.com/hc/requests/new) And tell them `setOnDim` is being ignored ---
