The lovelace basic I got configured relatively easily (shame your example uses _2 indexed units, mine are all _1, without that it would have worked just by changing the ps_id)
I couldn't find the images you have stored in /local though. So everything works once I installed the two front end addons canvas-gauge-card and mini-graph-card but the first status page doesn't give me the nice triangle view.
