Re: MMM-Tabulator - A demo module for using Tabulator to convert JSON data into a dynamic table
I’m using https://github.com/E3V3A/MMM-Tabulator
to download in Rasberry PI4 and trying to run .
as soon as i add following in config , it does not work , just shows Rasberry screen.
{
module: ‘MMM-Tabulator’,
header: ‘Tabulator Demo’,
position: ‘top_left’,
config: {
//fileUrl: “demo.json”, // The local filename or URL to JSON source
updateInterval: 180, // [seconds] Read the file every 3 min
