Subject: [PATCH] Filter null badges (#3645)

* Convert weather-forecast to LitElement

Part of https://github.com/home-assistant/home-assistant-polymer/issues/2095

Not sure how RTL works and how to apply it.

Also, thinking I should update if the forecast changes and not just the state. Input?

* Revert "Convert weather-forecast to LitElement"

This reverts commit e1893b0a83f5973df7a28e5d30c3d4d0496155a1.

* Filter out null badges

Closes https://github.com/home-assistant/home-assistant-polymer/issues/2974

* address review comments

* Update hui-view.ts
