Hi,
unfortunatelly porting is not that easy, since the ethernet library does not exists for ESP32. Anyway, I started porting to ESP32 – based on Ja.Carer’s work. Code compiles, but did not have the time to test it (yet) on my custom board; so any volunteers for testing are welcomed 🙂
Code is here: https://github.com/V1pr/OpenSprinkler-Firmware-ESP32
Please read the readme! Moreover, I’m not sure, if the bug in the Arduino-ESP32 library has been updated in platrofmio (bug with the F() macro calling).
