UK no-neutral light switch installation questions

Hey there all,

I have a no-neutral smart light switch that I'm looking to install, before I do so I just wanted to check 2 things, would be grateful for any help:

1. My current dumb switch is metallic and has what I assume is an earth wire (yellow and green) attached to it, the new plastic switch has no place for this, what should I do with it?
2. My current switch has two other wires: blue / L1 and brown / com. My new switch has two slots: L1 and Lin, I assume the brown cable goes to Lin and the blue cable goes to L1? (this might seem obvious, but I just want to sanity check)

Thanks,

DW

1. If you have a metal back box, then there should be a screw for you to put the earth into

2. yes 

hope this helps

Thank you!!
