Hi. I'm looking for help with trying to figure out how to combine two separate boards nodemcu and esp32 4-relay board in one sketch for use via blynk. can anyone tell me how to? I keep getting an error saying "Compilation error: ESP8266WiFi.h: No such file or directory"~ a conflict error. because the sketch needs to include both for esp8266 and esp32, but for some reason it cant.
Here's my code:

*************************************************************
This example runs directly on ESP32 chip.
Note: This requires ESP32 support package:
https://github.com/espressif/arduino-esp32
Please be sure to select the right ESP32 module
in the Tools -> Board menu!
Change WiFi ssid, pass, and Blynk auth token to run :)
Feel free to apply it to any other example. It's simple!

The BLYNK_WRITE(V4) and BLYNK_WRITE(V5) is being used by the nodemcu as sliders for pc fan speed control at 1023 variable.
Please help. Thanks.
