Hey, sometimes i get the following error. It happens maybe 2 times per week. Is there a solution to restart the usb device if it isnt reachable?

I think you have an older version of my app. On the newer version I am catching these errors, so it runs without issues. You can check it by comparing the file run.py on line 113.

is there an easy way to update?

bkbilly commented 2 months ago

Yeah, you can just go to the installation directory, download the new code and restart:

cd /opt/mqtt_fingerprint_pi
git pull
sudo systemctl restart mqtt_fingerprint_pi.service
