Lovelace Pie Chart Card

This card will display a doughnut chart based on your specified entities. This was based on https://github.com/cheelio/power-usage-card.

Usage

  1. Add plugin .js as a module:
- url: /local/pie-chart-card.js
  type: module

----iPa64 13.12.2020
About the bug with color not displayed, added the workaround proposed by MACscr (disabled auto update), not perfect but better than the original issue. Added attributes: chart_type: doughnut or pie display_legend: false or true Size modified, 150

Need to do: define size by attribute
