Hi,
All depend how much you want to spend, and which solution do you have in mind, and which one can be possible or not and also the visual design that you have implemented at home.
In case that you have places with switch and plug, maybe you don’t want to change the design, with 2 devices, and you want that all continue as you have, but behind the switch you have the smart electronic.
In my case i also want to make turn automate some switchs at home, but i don’t want chage the visual design, so i was testing with ESP8266 + relay and i will implement this solution. Here you have a little example with 2 relay, 2 lamps and 2 switched.
In that case, i’m using a ESPEasy firmware, and needed to make a little code, to synchronice the switch with relay, and how the state in home assistant.
