Am I doing this right? Configuration doesn't seem to be applied

Hello. Last month I had a card on my overview with grouped lights. Now they are gone, and I have no clue why, I never added them manually they appeared after integrating with IKEA trådfri.

I Want them back in the overview so that I can easily turn on/off all my lights in my living room. I have tried various things but no success…

I tried this: https://www.home-assistant.io/integrations/light.group/

So my configuration.yml end up looking like this:

# Configure a default setup of Home Assistant (frontend, api, etc)
default_config:

# Uncomment this if you are using SSL/TLS, running in Docker container, etc.
# http:
#   base_url: example.duckdns.org:8123

# Text to speech
tts:
  - platform: google_translate

group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml

# Example configuration.yaml entry
light:
  - platform: group
    name: Living Room Lights
    entities:
      - light.loft_1
      - light.loft_2
      - light.symfonisk
      - light.stand

This is how my overview look before and after adding the “light:” to the configuration and restarting.

I have gone through just about all the files in my config folder, and non of them seem to define this overview that I am seeing in my browser, and nothing changed since I added that light group. Are there another configuration.yml somewhere else that I am missing, and are currently touching the wrong file?

I’m thinking that Im following guide that matches other version of HASSIO, or that I am touching wrong files… I also haven’t been able to find a “known devices” anywhere, I would really like to locate this file to assign better names, icons etc to stuff…

This are the files I have available in the config folder:
Untitled

I’ve also tried various youtube video guids, but that seems to lead to more frustartion as the UI has changed a lot and for a newbie like me it is impossible to figure out which buttions/sections/pages in my current UI that matches the UI in the youtube videos.

Please tell me what I am doing wrong.
Thanks!

Bonus info, I am running HASSIO on a raspberry pi wired connection. (HassOS 2.12)

Correct. It is using LOVELACE to display things. If you haven’t taken control of your Lovelace then it should show things by default, automatically.

Are you sure your lights are still connected to Home Assistant? Open developer tools, states, and look for your lights. If they show up then just go back to the overview, click on the 3 dot menu in upper right, and CONFIGURE UI, take control, and add a light card with your lights.

If you aren’t using official documentation, you aren’t following current guides.

Because it is deprecated and is only still used by a handful of device trackers.

That’s not how you do it.

You use the CUSTOMIZE option in your CONFIGURATION page.

Don’t

Thats some pretty sharp direct answers. Thanks a lot man!

First thing I did was following my intuition before even starting to google stuff. So I actually already clicked the three dots then the plus button, but i could not find a “light group” instead I see an option for a single “light”

And when clicking that the next step in the setup give me the possiblility to select just one of my lights listed in the entity drop down.

This is certainly better than nothing, but it is not how my previous light card looked like., it had multiple lights in it, to be precise, all the lights in my living room was in it and with one click i could turn off all of them. Is that somehow still possible to setup?

Also… are this overview saved to some file that i can look into? Or is it stored in a db not readable for humans and can only be edited through the UI now ?

You are wanting an “ENTITIES” card then.

They are stored in JSON files in a hidden .storage directory in your config directory. You don’t edit these while the system is running, and is generally frowned upon to edit these files.

Sweet. I think I am able to proceed from here. Again, Thanks a lot.
