Post: Hi The problem you are having is most likely caused by a conflict between the IO Pi and the RTC. Linux will periodically communicate with the RTC. When this happens the I2C bus is blocked from all other communication so if you try to access the IO Pi at the same time you will get a Remote I/O error. The easiest way to get around this problem is to use a try/except around the write_pin function call in python code and if an error occurs wait for a few milliseconds and try repeating the write_pin call. The other option would be to disable the i2c-rtc and ds3231 overlays and write a python program to manually get the date and time from the ds3231 and update the system time when the Raspberry Pi boots.
