Cannot define any - platform statement behind sensor:

Configuration
#1

Hi guys,
I am fairly new to HA and after countless futile attempts and days of google research I ask you now.
I try to define the systemmonitor according to the official documentation like this:


mqtt:
 device_tracker:
   - name: "NodeMCU SZ"
     state_topic: "ac0bfbd67288/state"
     unique_id: nodemcuszstate

 
 sensor:
   - platform: systemmonitor
     resources:
       - type: disk_use_percent
         arg: /

   - name: Raspi4 Nodes
     state_topic: "raspi4mqtt/sensor"
     unique_id: raspirpi

Unfortunalety that does not work.
The HA configuration checker says:

Invalid config for [mqtt]: [platform] is an invalid option for [mqtt]. Check: mqtt->mqtt->sensor->0->platform. (See /config/configuration.yaml, line 56).

Is the documentation wrong, or am I making a mistake?

Any hint appreciated.

What file is this in?

And are you sure the indentation shown above reflects what is in your file exactly?

  1. It’s in configuration.yaml
  2. Yes - I did a copy/paste from VSCODE into the post.

btw. Any “- platform” ( below the sensor: ) leads into an error. Even the command platform.

My environment:
Home Assistant 2023.2.5
Supervisor 2023.01.1
Operating System 9.5
Frontend 20230202.0 - latest

running on hassio on an Odroid XU4

As the error message states, platform is not a valid configuration variable for the mqtt platform… I suspect you are trying to do something like the following:

mqtt:
    device_tracker:
      - name: "NodeMCU SZ"
        state_topic: "ac0bfbd67288/state"
        unique_id: nodemcuszstate
 
    sensor:
      - name: Raspi4 Nodes
        state_topic: "raspi4mqtt/sensor"
        unique_id: raspirpi

sensor:
    - platform: systemmonitor
      resources:
        - type: disk_use_percent
          arg: /

Sensors that are not based on the MQTT platform cannot be added to the same list as those that are. You need a top level sensor configuration key.

@ Didgeridrew:
as you can see in my first post, I definitely have only one sensor key as described in the HA documentation.
If I put the sensor statement on the same level as mqtt I get
Invalid config for [sensor]: required key not provided @ data[‘platform’]. Got None. (See /config/configuration.yaml, line 68).

Just tried to define the systemmonitor on the mqtt level


systemmonitor:
   - platform: systemmonitor
     resources:
       - type: disk_use_percent
         arg: /
mqtt:
.
.
.

but that don’t work either:
Setup failed for systemmonitor: No setup or config entry setup function defined.

In your first post you have 0 top-level sensor keys. You have 1 sensor child key with mqtt as the parent. Under that you have a configuration stanza for 1 MQTT sensor, and 1 non-MQTT sensor.

As shown in the example I posted above. Your MQTT-based sensors must be children of the top-level mqtt key… non-MQTT sensors must be children of a top-level sensor key.*

That is not what I showed above…

YAML for non-programmers

*Note: Other top-level keys can also have sensor children, but sensor is the most common parent key for sensor integrations.

#7

Finally!
I’m not sure I’ve got the configuration guidelines right now, but as you suggested above, I’ve defined an additional top-level sensor statement after my other sensors and - it’s working now.
You are my hero of the day.
Thank you very much!
