What
Workstation in Zaal 2. It has a barcode scanner which can be used for Partkeepr.
Auto shutdown
We want this machine to shutdown when space is closed. We check MQTT for this in a simple python script. We use paho, so let's install that:
apt-get install python-paho-mqtt
Normally the script would ask for a password to execute the shutdown command. We can avoid this with following line in /etc/sudoers (use visudo for this):
hark harktv =NOPASSWD: /bin/systemctl poweroff
Now we just run a cronjob every 5 minutes:
