Raspberry pi + ordinary switch: how to make lighting control?

Question

Raspberry Pi

There are a lot of articles on the Internet on how to use the raspberry pi to turn on and off the lighting (for example, a table lamp) remotely.
Unfortunately, I can not find an implementation so that in parallel it would be possible to turn on / off the same lamp from the button. For example, remotely turned on, and turned off the lamp with the button.
How can this be implemented? What should the diagram look like?

Answer 1

Connect button to pi. Catch the button click event.

Answer 2

Logically. Thank you. I think the issue has been resolved.
