@jhillairet the modules will have to agree on the chartjs version used. pick one and change the others version number in package.json then npm install that one again after the change

@jhillairet I get all the data and format/filter in the node_helper, then send to the modulename.js to display. as I support multiple instance the messages have the module indentifier to keep the data separated

@jhillairet Hey, i would recomend you to do all in javascript. I love python, but what you’ve planed is perfectly doable in javascript. See chart.js for example. As long as it’s possible to write a project in one language, i would never combine more languages.
