Shelly dimmer not dimming

Hi all,

I just flashed a shelly dimmer 2 with esphome, since the device is now supported after some time. I followed the esphome documentation: Shelly Dimmer — ESPHome, and used the suggested configuration. All is working fine, except the dimming. The dimming function is showing in home assistant, but nothing happens when i move the slider. I can turn the light on and off but can not dim it. Any suggestions?
