SS Panel questions (UK based)

Morning
I’ve been reading up on the SN Panel and have a few questions:-

I am in the UK, can the US vertical NS Panel be used in the UK? Can it be made to fit into a standard uk wall patress? (Plasterboard patress). How deep does the patress need to be to support them?

Where I currently have a wall switch with 2 switches on, for 2 lights in the room, can one of these replace that and control both circuits as a direct replacement?

What do the physical buttons do? I have to be mindful of WAF and ensuring everything is easy to use (plus for visitors). Could one button simply operate light circuit 1 and the other 2? Simple press once to switch on, again for off and hold to dim? (Therefore operating almost same as old switches)

What sensors are built into these devices?

Are they powered from the lighting circuit? Do they therefore need live and neutral in each patress?

Can they be set to switch off or dim at night so they don’t keep people awake in bedrooms?

Sorry for the basic questions, I want to understand the limitations and flexibility before ordering one.
