If you are not familiar with bundling and you don’t need to make your dashboard available w/o internet, you can do:
import "https://cdn.plot.ly/plotly-2.4.2.min.js";
Or: you can use this plotly card instead
I made this plotly graphs card with some bells and whistles. It follows your HA color theme, updates the data on real time, allows you to go beyond to the past by scrolling, and some more features… It should generally just do what you’d expect. I hope it fits your needs
