Just in the middle of moving my Home Assistant from a Pi3 to a Pi4 and it seems i2c isn’t working on the Pi4.
Just tested the same USB stick called CONFIG with the relevant folder and two files (following these steps here on a Pi3, it works fine - i2c enabled on reboot. On a Pi4, it doesn’t do anything.
Traceback (most recent call last): File "/usr/local/lib/python3.7/site-packages/smbus/smbus.py", line 81, in open self._fd = os.open(path, os.O_RDWR, 0) FileNotFoundError: [Errno 2] No such file or directory: '/dev/i2c-1'
Has anyone come across this yet?
