Nexa in-the-wall MWMR-251

Hi all, I just bought my first Homey (Pro 2023), so pardon the perhaps newbie question.
I am trying to add all my older in-the-wall Nexa devices but I have little luck.
I have a large number of the dimmer/switch MWMR-251, a very convenient little thing that also allows me to control and sim the lights with a regular switch.
I just can’t seem to add it to my Homey. I have tried as advised from an older post here but using the Trust Smart Home app and the settings for ACM 250, but no luck.
I can not get it to copy from the Nexa remote either. What am I doing wrong?
Tips anyone?
