Legrand k4411C dimmer value

Hi Everyone,
I have linked through netatmo cloud the only dimmer i have in my house for now.
However, the value of the dimmer seems offset. when i go to the device, and i set to a value, the value in the google home app or app+control app is different. e.g. setting to 51% in homeassistant sets to 89% the dimmer.
How can i solve this issue? i was not able to find the config in order to change the value properly.
Thanks in advance for your help

seems that it is sending something different:
I set the value using the GUI but the log says:

There is no correlation between what i set in homeassistant and what the netatmo api is sending.
Is someone able to give me a tip where to look?
thank you
