Hello, I had to modify the Arigata project from ESP32 to ESP8266 because I couldn’t compile the software, and I have a few questions. Under which GPIO pins are the buttons B1, B2, and B3 located? the sensors Sens1 and Sens2?
Can such an analog sensor as shown in the picture be connected?
The pins defines are all in the firmware code defines.h: https://github.com/OpenSprinkler/OpenSprinkler-Firmware/blob/master/defines.h#L388
assuming you have OpenSprinkler version 3.2 (previous versions use different pins, and they are all defined in the file as well). IO_EXP + ? means it’s pin number ? on the PCA9555 IO expander.
