Web UI for easy viewing of entity states

[mKeRix]

The iOS companion app has received an instance browser, which in its current version serves as a way of viewing live entity data. This is quite useful to e.g. fine-tune the maxDistance and minRssi settings, since you can follow the current state live while moving your device around.

It would be cool to have this available on the web, to have a platform-agnostic way of seeing this data. It would also improve UX in general. For the first iteration entity data should be enough imo, but more things can then be added on top later on.

@mKeRix - I like it!

It's pretty simplistic, but before Instance Browser, this was an easy way to get an overview as walked the house with my tablet running Home Assistant mobile and Node Red.
