your question is about interfacing the e-paper display ... why does your program contain code relating to weather and to wifi? ... reduce the code to minimum required to display something on the e-paper display – jsotola Jun 28 '20 at 19:23
Maybe I have the same problem on a ESP32 NodeMCU with a waveshare 1.54 inch display. Did you solve the problem? – monok Nov 6 '20 at 8:03
