Why do I usually get this error on the console?
After the second or third attempt the info is listed?
sudo wee_device --info

You need to stop WeeWX before running wee_device - according to the log extract you posted both WeeWX and wee_device are competing to talk to the console. wee_device happens to work sometimes if it tries to communicate with the console when WeeWX is not.

Yes, that's how it works without mistakes, thank you.
Is this in the documentation, or do you just know this?

If you look in the logs, you'll see:
