The results are really awesome!
I have updated the Pi Lab Stats page to incorporate these dashboards.
If you are interested in how I set this up check out this GitHub repo. https://github.com/bhemar/raspberry-metrics.
Pi Lab Metrics Playlist
I have made some updates to the Pi Lab Metrics dashboard to include more graphs. I have also finally added the Pi-hole/OpenVPN Node to the dashboard.
I have created a Grafana Playlist to cycle through each node in Pi Lab.
