It is not like the sudoers. It is just a group.
Look here:
https://www.techrepublic.com/article/how-to-create-users-and-groups-in-linux-from-the-command-line/
It will show you how to add the group to the user.
If the sudo wee_device comes back with command not found then that means it
is not in the path and then you will have to usr the absolute path to run
the command.
E.G If the wee_device is in /home/weewx/bin then you would have to run:
sudo /home/weewx/bin/wee_device
