Please update web.py, where port 5000 is hardcoded.

It's not hard-coded, that argument is just a default, and gets overwritten with whatever is in this configuration setting: https://github.com/projecthorus/radiosonde_auto_rx/blob/master/auto_rx/station.cfg.example#L473

I got it working by removing the .pyc files. Indeed, it works.
