How to delete all Things at once

I just started using this project on my RPi3 a few days ago. Mostly just experimenting. Now I want to delete all my found Things and do a full rescan. Is it possible to do this? If not, can I manually just delete the db.sqlite3 file? I don’t want to lose my login credentials by doing a full reinstall. Any ideas are welcome.

You can do it manually.

sqlite3 ~/.mozilla-iot/config/db.sqlite3 "DELETE FROM things"
sudo systemctl restart mozilla-iot-gateway

Super! Thank you for this info.
