Template sensor not showing as entity

Configuration
1

hey everyone so i hope you can help me out :).

I´m trying to add an offset to one of my temperature sensors. The sensor is a tasmota flashed Wemos D1 and the sensor is a ds18b20.

So i used a template sensor but it´s not showing up nowhere. I tried with the tempalte sensor given in the docs (maybe i got a typo or something) but that is not showing up either.

I searched and tried for like 4 hours so you guys are my last resort :).

here is my configuration.yaml:

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

and here is my sensors.yaml:

  - platform: systemmonitor
    resources:
      - type: disk_use_percent
        arg: /home
      - type: memory_free

  - platform: template
    sensors:
      fernwaerme_ruecklauf_korrigiert:
          value_template: "{{ states('sensor.heizungs_ueberwachung_ds18b20_3_temperature') | float + 20 }}"
          friendly_name: "Fernwärme Rücklauf Korrigiert"

The systemmonitor is working but the template sensor is not showing up anywhere. If you need more information i will provide it. I´m very new to Home Assistant and i´m learning by doing :).

PS.: My wake on lan switch isn´t working too buts that´s another question :D.

Indentation. Use 2 spaces per level consequently.

Take a look at the example.

I did changes to my YAML files but still no template entities. Looked up in developer tools too.

sensors.yaml:

- platform: systemmonitor
  resources:
  - type: disk_use_percent
    arg: /home
  - type: memory_free

- platform: template
  sensors:
    fernwaerme_vorlauf_korrigiert:
      value_template: "{{ states('sensor.heizungs_ueberwachung_ds18b20_5_temperature') | float + 20 }}"
      friendly_name: "Fernwärme Vorlauf Korrigiert"

Changed the sensor too but no changes.

No errors in the logs. The wake on lan issue we keep for later :slight_smile:

Just got solved with the guys over in the Discord channel.

Problem was that my restart button in the gui did not really restart my home assistant (running on a raspberry pi).

So i had to manually restart it with the console command ha core restart

I have a theory why that might be happening but I would need you to perform a simple test.

Execute Configuration > Server Controls > Check Configuration.

Let me know if reports “Configuration valid!” or an error message.
