One I get this up and running, I'd be more than willing to post my process as the setup is already documented. I've shutdown the RPi and am about to image what I have so far, restore an image of Buster installed and updated with my WD setup, and then try to reinstall the Node-Red/InfluxDB/Grafana again using the influx repo.
I re-read the Hubitat > NodeRed > MySQL > Grafana (LONG READ) thread and made a few notes on how to try and get it setup once the required components are installed and tested. How hard would that portion be to script out?
