if you want to use ESP 8266 EEPROM library (4kbytes in the flash mem.) you have to use ModAfterUpload branch.
Then you can go on just with ESP8266+RTC. Have a look to proto 2 in the pins.h file for the #define
Anyho have a look to the OpenSprinkler web site to have an idea of the hw components necessary for operation of the Open Sprikler station: 3 buttons, an LCD 16x2 + or a shift register cip or an extender like PCF8574
It is possible to use the components you like and the GPIO you prefer as long as you put the right define in the pins.h file.
If you want to look to one of my prototypes there is schematic png file in the github
