This did work, thank you very much. The template node needed to be set to Output as Parsed YAML, and the "msg": string needed to be in quotes. So like "msg": "{{payload}}",. That worked like a charm.
The only issue now is getting each sensor to output to its own section in the array. I was able to get them to display their own separate values on their own line with a change node, but its causing the display to just alternate between the values displayed on each line; it's not able to show everything at once.
This may be an issue to try to ask the developer of the lcd node, but I'd very much appreciate some ideas to make this more efficient. But your idea there, Andrei, put me way closer to a solution, thank you very much.
