1 month ago +1, would be interested in a solution as well. I read https://github.com/njanik/hayward-pool-heater-mqtt/issues/15 but that doesn't solve it for me. I'm using a Wemos D1 mini. Adding a return true; solves it for me, but I'm afraid that is not correct. However the error message seems valid to me, it's a non-void function without return value. @njanik

Hi there,
I have similar issue as Nicolas during the compilation of the code: E:\Arduino\hayward-poolheater-mqtt\hayward-poolheater-mqtt.ino:5:23: warning: extra tokens at end of #include directive 5 | #include "my_config.h"; | ^ E:\Arduino\hayward-poolheater-mqtt\hayward-poolheater-mqtt.ino: In function 'char modeToString(byte)': E:\Arduino\hayward-poolheater-mqtt\hayward-poolheater-mqtt.ino:65:16: warning: ISO C++ forbids converting a string constant to 'char' [-Wwrite-strings] 65 | return "HEAT"; | ^

I understand I need to install the Arduino Core. But I think I am lost with that part. Is this the ESP8266 package from the board manager menu that I need to install? Or any other Library/package needed? Also, is there any specific version to use?
I am also newbie with this and I am trying to learn!
