Ok fantastic. Thanks very much. I have been running my v3 ESP8266/DC very successfully. Great features:)
The reason I was mentioning an EEPROM as it looks to be a new hw resource v3, and was just interested in any thoughts about it.
The schematic I found on github – https://github.com/OpenSprinkler/OpenSprinkler-Hardware/blob/master/OS/3.0/Master/os33_master.png
has a device 24C02 and there is a reference to detecting it in the code a
OpenSprinker.cpp:
// revision 2 and 3
if(detect_i2c(EEPROM_I2CADDR)) { // revision 3 has a I2C EEPROM
hw_rev = 3;
} else {
hw_rev = 2;
}
