 Description | The outputs are controlled with a PNP transistor. In this case the ESP signal logic is needed to be inverted programatically to get the supposed signal at the output. | The outputs are simply pulled up with a pull-up transistor. The ESP signal logic is inverted here too as well as the output signals which means the relay has to be used invertedly.

 The ESP8266 was not the best choice for solving this problem as it needs the aforementioned controlling circuit. With an ESP32 this whole project could have been solved more easily. The reason I carried on with the 8266 variant is the following: solving the problem looked a great learning experience which turned out to be true. Understanding how to control the relay and designing the PCB was a satisfying experience.
