ACCESS_TOKEN, Widget

[RonnyWinkler]

• Added possibility to use an ACCESS_TOKEN in env.json for local test
  Changes in driver.compose.json (added loading pair screen to check ACCESS_TOKEN
  Added token usage in api.ts

• Added Homeys widget for Home and Pulse device
  Added API function in app.ts
  Added realtime events in home and pulse device to send updates to the widget
  Widget folder with widget definition and html elements

When you add a field ACCESS_TOKEN to env.json, this is used. If this is not set (official Tibber version, the pais screen should continue with the oAuth screen. Please check this before publishing the app (I tested without access token and client id and the oAuth screen was shown).

The widget can show energy data from Pulse device (assign the Pulse device in widget settings):

The widget can show price information with or without chart (assign home device in widget settings):

The widget offers several options

• show/hide chart
• zoom chart (yAxis)
• show simple line or colored chart
• color options for: color based on price level, color based on price range (1/5 of corrent range), vertical area color bases on price level.
