Simple Examples needed

I have just installed Home-Assistant and basically it works fine. But I just have a whole bunch of small icons at the top (except for the ‘lights’).

Are there some basic examples, e.g.

  • how to show one (or more) MQTT message(s) in a card?
  • how to decode the json of a MQTT payload and show the strings in a card?
  • how to show the net-atmo values that are shown when clicking one of the icons in a card?

It seems I missed the documentation for that somehow…

Thx

Thx for the link.

Do you know how to get multiple values at once? Or do I need to create a sensor for every value?

And what do I need to do to show the values in a card (e.g. as string)

  • battery
  • location

To get a map and stuff, I guess I need to create a python script; or can I do that on the frontend using Javascript?

thx
