Hello, I got my node-red flow connected with mqtt broker to switch relays with my weimos d1 mini and modbus relay board. When upload my code to esp8266 it doesn't show anything on my serial port COM4 - 115200 : It should show if it connected correctly to my WIFI etc and everything written in my code…

Esp8266 no serial prints / connecting to WiFi and MQTT Broker problem
