I see that some of you tried to run the hardware with a NodeMCU which is based on ESP8266. Mmaybe someone can help me with my questions.
I´ve compiled the code which is on a NodeMCU v3 now.
But I do not know, how the outputs are connected to the esp8266. Is there a shiftregister (74HC595) like for the OSPi?
Also how is the rainsensor connected?
