Can't calibrate LED bulb

    I have a Shelly Dimmer 2 that has been connected to a halogen 70W bulb and been working fine. I tried connecting a new 9W LED dimmable bulb, but when I calibrate it, it gets to 13% and then the bulb starts flickering and the dimmer2 loses power every time so it can't complete.

    I set it to Leading Edge and it managed to calibrate but then every time I switch it on it turns off after about 5 seconds and the webpage says "wrong calibration".

    I think it's sending too much power and overloading the bulb, though I am far from an expert. Is there a way I can manually calibrate or some settings to try? I fiddled with debounce settings but I don't really know what I'm doing, none of my other dimmers are attached to LEDs.

    Thanks in advance!

    Is the Shelly Dimmer2 connected with neutral wire? If not, you’ll need to connect a bypass in parallel to the load, cause the minimum load für Shelly Dimmer2 without neutral wiring is 20W.
