I don’t know what more you are expecting here… copying others code is generally acceptable here, but don’t pass it off as “yours”… [SOLVED] Turn on and off relay with blynk button and/or physical button - #36 by dutchman
Many people purposely leave code for others to use, but you still need need to learn how to understand it in order to modify it and eventually write your own code.
