Covert outdoor lights from timer to smart

[jimmybond007]

I have outdoor lights that are controlled by dusk sensor and then timer (for OFF) on the right of the picture. The switch to the left of the box powers off the entire fusbox therefore I cannot change that as I have other things I keep on). What do I need to buy (switch/plug?) to swap the old timer out to then make my lights smart (I dont get care about losing the dusk function).

Thanks
