Sorry Greg, should have mentioned that I already tried running it with
sudo, with interesting results. Here's what I get, running without sudo,
then with sudo...
. . .
weewx@weewx:~ $ wee_device --clear-memory
Using configuration file /home/weewx/weewx.conf
Using Vantage driver version 3.2.1 (weewx.drivers.vantage)

During handling of the above exception, another exception occurred:

weewx@weewx:~ $ sudo wee_device --clear-memory
[sudo] password for weewx:
sudo: wee_device: command not found
So how do I add the user to the dialout group? Is that like the sudoers
group? (not sure how to do the sudoers group either).
