Some news on my side, the first TTGO version boards (v1) came and they are running fine with a modified code from the ja.charer fork. I had to do some small bug fix for the rtc and need still need to change one diode to allow proper current measurement with the ESP32 (the ADC is worse than the ESP8266 one). Attached you can find the pictures. Soon I will get the version 2 produced and start working on the LoRa driver to remotely control the irrigation system w/o need of internet.
From this version 1 (TTGO based) I have 5 boards, but will need just 2 of them. In case of interest in any of the 3 remaining boards please let me know.
