How to start Grafana dashboard on Linux MiniPC (LRO-PC-09) for my UKRAA Cosmic Watch muon detectors

Muon detectors x2, one on top of other, linked by 3.5mm audio cable, and USB cable plugged into BOTTOM detector and going to MiniPC rear USB port – tested and works with USB to left of VGA monitor port looking from back of MiniPC.
Turn on MiniPC. Connect to home network via LAN cable. The dashboard runs whilst machine turned on & connected via LAN.
(Service to collect muon data has been set up by Rhys to automatically start, so does not need to be separately started by user.)
On Linux MiniPC, dashboard can now be edited by opening browser and navigating to http://127.0.0.1:3000/
(Note in above it is http:// and NOT https://)
The public dashboard can be viewed at https://cosmicwatch.astronomy.me.uk
