It seems to me from your post that you are unqualified to do stuff with mains electricity, therefore I would suggest you should not go near it without a qualified electrician to do it for you. If you have one who will help you there are ranges of equipment that can be installed inside/instead of light switches, plugs. etc that your pi will talk to by wireless means (safely!). You could then use HA (or other home automation) software on a Pi or similar to control your lights, plugs, etc. If you don't have an electrician then an alternative would be to buy light bulbs or plugs that talk to HA via the Zigbee wireless protocol (for example). Try to keep to a protocol and products that are pretty universal (and avoid things that only work with one manufacturers products).
Please do some research on home automation hardware and software before going further.
The consequences of unqualified work with mains electricity could make your home insurance invalid, and, in the event of an error kill you or someone else by electrocution or fire. If I have misinterpreted your post/intentions/qualifications please forgive me.
