Dimmer 2 turn on led

Hi to all, yesterday night i noted a strange behaviour of dimmer 2.

(I have connected dimmer with neutral cable on 230v - italy).

The problem is that during the night the light went on by itself.

Nobody turn on by the app / physical switch /other methods.

The strange thing is that in the app this events don't appears but on home assistant appear like a somebody push physical switch....

What could have happened??

Ok but if in the app that event there aren't i think that the response of that API will contain the last status before..

however if it happens again I'll try to see
