Hi!
I’d like to create a library to use a class that controls the Yeelight Smart lights. I’ve got the code that sends the commands working so that is not an issue. Then I created the class within the main sketch and it worked perfectly.
Finally, when I try to move the class to a new library I can’t get it to compile. I’ve been trying all kind of things I’ve seen online for hours but nothing seems to work!
I’m using the ESP8266-ESP12E.
The error message is:

The code Yeelight.ccp:
#include "Yeelight.h"

}
void Yeelight::begin(IPAddress lightIP, int lightPort)

_lightIP = lightIP;
_lightPort = lightPort;
}
void Yeelight::toggle()

Any help will be much appreciated!
Thank you!
