help please with using a pir, dimmer and scene!

Pulling my hair out on this.

Pretty sure its my lack of knowledge in scenes rather that a config issue with my qubino dimmer module.
Ok I have a Qubino dimmer (new plus type) powering outside lights on a scene after sunset at 15% dimming…works perfectly as it should.

I have wired outside pir’s that send a switched live to the qubino module. (new type modules take live at there Inputs as aposed to neutrals on the old versions)
I want a scene that when a pir is tripped, it will run the dimmers up to 100% for x amount of time then revert back down to the original 15%, and reset so that if tripped again it will do the same.

I have tried connecting the pir switched live to input 1 (which is the control overal of the dimmer i believe) and input 2 which is basically a on off. im getting mixed results and i think i need help!

Thank you in advance

Chris
