I created a YAMon webapp:
Create a file /usr/share/turris-webapps/10_yamon.conf
:
URL="/yamon"
NAME="YAMon - Usage Monitoring by Device"
ICON="yamon-logo.png"
Go to the webapps icon directory
cd /www/webapps-icons
Grab the yamon-logo.png from the YAMon site:
wget https://usagemonitoringcom.ipage.com/current/images/yamon-logo.png
Reload your main interface.
