Help with two UK Light switches - Trying to make smart!

Hi all,
Just wondering if anyone could give any pointers. The first switch I have controls the garden lights. It appears to be a fused switch. Here are some photos.

The second is for the lights in the garage. There is a switch by the garage door, and then another at the other end by the rear entrance to the garage. Here are a few photos:

What do you think would be the best way to do this? Would a Shelly2 be the best option?
