Sounds like a python 2/3 mismatch to me. What version of python does WeeWX run under? Check the WeeWX log during startup, it may be different to the version invoked by the ‘python’ command from the bash prompt. How did you install smbus2? With pip or pip3? If WeeWX is running under python 3 and you installed smbus2 using pip and not pip3 WeeWX/python will not be able to find smbus2.
