HA not using configuration.yaml

Configuration
1

I have installed HA on a RPi4 and I have a lot of integration working “out-of-the-box” - like Philips hue and TP-link and others - but it seems that no matter what I put in the /config/configuration.yaml nothing changes. I have tried to add several different sensors with no luck. Nothing new shows up in the “Entity” list or anywhere else.
I have tried to add some very basic sensors directly from the documentation (copy/paste) still no luck.
Like:

sensor:
# My IP
  - platform: rest
    resource: http://ip.jsontest.com
    name: External IP

or

sensor:
  - platform: yr

I have validated the configuration, restarted the service and rebooted the server.
I have also tried to see if there is anything in the log files - but they are almost empty.
I have tried to add a mistage and it validated it with an error - so the system looks at the configuration file.

This is the complete file:

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

# Text to speech
tts:
  - platform: google_translate

group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml
#customize: !include customize.yaml

sensor:
# My IP
  - platform: rest
    resource: http://ip.jsontest.com
    name: External IP

Did you check in the Sidebar under Developer Tools -> States, if you can find the entity there?

Yes. I can find it under Dev tools. :no_mouth:
