This software stopped working after 30 July 2016 when Habitica's deprecated API v2 was removed.
Information about the API change can be found at Application Programming Interface.
- Download httpful.phar and put it somewhere convenient (/usr/local/share/php/httpful.phar)
- Download the habitrpg_* files into your munin installation. (I usually store external plugins in /usr/local/share/munin/plugins/)
- Edit the downloaded files and include your Habitica information (path to httpful, uuid, key and optionally username)
- Link the plugins into your munin plugin dir (ln -s /usr/local/share/munin/plugins/habitrpg_* /etc/munin/plugins/)
- Restart munin-node
