Just using Node-RED since some months and building some flows for home automation.
For example: I am using some cast nodes (e.g. node-red-contrib-castv2) to send latest images from webcam to my Google Nest Hub via Chromecast.
Today I found https://cast.home-assistant.io/
A service that casts the Home Assistant Dashboard to any Chromecast device. The special "magic" is the support of the user interactions on touch devices like Google Nest Hub (no browser embedded in Google Things!). You can click on switches and sliders and the interaction is recognized. MAGIC!
Here you can find a video from Home Assistant:
Would it be possible to have it in Node-RED?
