Landscape lighting

I am about to get my yard landscape in the back and our landscaper suggested 12v landscape lights to high light some steps, trees and other areas of our yard. I am sure I can put a system myself by other than off an on and wiring multiple relay for multiple zone is this pretty basic. Anyone done anything like this and hooked it in to HA>

I recently installed 12v dumb lights to light up the tricky path to our spa pool. I have just bought a smart power strip to be able to turn on/off from ha.

I did the same - 12v lighting on a transformer and just put a smart switch on it
