MQTT Sensor and Switch configuration

Configuration
1

Hi all,

I’m trying to update my MQTT platform config from an old HA version to the latest. But I must be doing something wrong. Can’t seem to see where I’ve gone wrong.

This is the original 2021 version config (doesn’t work any more with the latest HA version):

  - platform: mqtt
    name: "Outside Temp"
    state_topic: "outside/waterheater/tele/SENSOR"
    unit_of_measurement: '°C'
    value_template: "{{ value_json['AM2301'].Temperature }}"

switch Water_Heater:
  name: "Water Heater"
  platform: mqtt
  qos: 2
  state_topic: "outside/waterheater/stat/POWER"
  command_topic: "outside/waterheater/cmnd/POWER"

I’ve tried updating it to the current version but I suspect I have something slightly wrong here?

mqtt:
  - sensor:
      name: "Outside Temp"
      unique_id: outside_temp
      state_topic: "outside/waterheater/tele/SENSOR"
      suggested_display_precision: 1
      unit_of_measurement: "°C"
      value_template: "{{ value_json['AM2301'].Temperature }}"

  - switch:
      name: "Water Heater"
      unique_id: water_heater
      state_topic: "outside/waterheater/stat/POWER"
      command_topic: "outside/waterheater/cmnd/POWER"
      qos: 2
      payload_on: "1"
      payload_off: "0"

Why? What makes you think that?

Using Quick Start from the Developer tab I get this error:

Cannot quick reload all YAML configurations because the configuration is not valid: Invalid config for [mqtt]: expected dictionary for dictionary value @ data[‘mqtt’]. Got [{‘sensor’: {‘name’: ‘Outside Temp’, ‘unique_id’: ‘outside_temp’, ‘state_topic’: ‘outside/waterheater/tele/SENSOR’, ‘suggested_display_precision’: 1, ‘unit_of_measurement’: ‘°C’, ‘value_template’: “{{ value_json[‘AM2301’].Temperature }}”}}, {‘switch’: {‘name’: ‘Water Heater’, ‘unique_id’: ‘water_heater’, ‘state_topic’: ‘outside/waterheater/stat/POWER’, ‘command_topic’: ‘outside/waterheater/cmnd/POWER’, ‘qos’: 2, ‘payload_on’: ‘1’, ‘payload_off’: ‘0’}}]. (See /config/configuration.yaml, line 444).

Choosing to restart throws this usual message this is indicative of an invalid config file.

When I remove the above config, restart is fine.

OK a lot of trial and error and I worked it out. Here’s what I’m using:
NOTE: The specs in the documentation don’t seem right to me. Their examples don’t work in my latest HA version. Note the grouping, dash and indentation differences.

mqtt:
  sensor:
    - name: "Outside Temp"
      unique_id: outside_temp
      state_topic: "outside/waterheater/tele/SENSOR"
      suggested_display_precision: 1
      unit_of_measurement: "°C"
      value_template: "{{ value_json['AM2301'].Temperature }}"

    - name: "Outside Humidity"
      unique_id: outside_humidity
      state_topic: "outside/waterheater/tele/SENSOR"
      unit_of_measurement: "%"
      value_template: "{{ value_json['AM2301'].Humidity }}"

  switch:
    - name: "Generator"
      unique_id: generator
      state_topic: "energy/generator/stat/POWER"
      command_topic: "energy/generator/cmnd/POWER"
      qos: 2

    - name: "Generator 1Hr"
      unique_id: generator1hour
      state_topic: "energy/generator/cmnd/POWERAuto"
      command_topic: "energy/generator/cmnd/POWERAuto"
      qos: 2

Odd, the specs in the docs work fine for me, and others:

mqtt:
  - sensor:
      name: "Outside Temp"
      unique_id: outside_temp
      state_topic: "outside/waterheater/tele/SENSOR"
      suggested_display_precision: 1
      unit_of_measurement: "°C"
      value_template: "{{ value_json['AM2301'].Temperature }}"
  - sensor:
      name: "Outside Humidity"
      unique_id: outside_humidity
      state_topic: "outside/waterheater/tele/SENSOR"
      unit_of_measurement: "%"
      value_template: "{{ value_json['AM2301'].Humidity }}"

  - switch:
      name: "Generator"
      unique_id: generator
      state_topic: "energy/generator/stat/POWER"
      command_topic: "energy/generator/cmnd/POWER"
      qos: 2
  - switch:
      name: "Generator 1Hr"
      unique_id: generator1hour
      state_topic: "energy/generator/cmnd/POWERAuto"
      command_topic: "energy/generator/cmnd/POWERAuto"
      qos: 2

Definitely does not for me. I’m getting this error:

Invalid config for [mqtt]: expected dictionary for dictionary value @ data[‘mqtt’]. Got [{‘sensor’: {‘name’: ‘Outside Temp’, ‘unique_id’: ‘outside_temp’, ‘state_topic’: ‘outside/waterheater/tele/SENSOR’, ‘suggested_display_precision’: 1, ‘unit_of_measurement’: ‘°C’, ‘value_template’: “{{ value_json[‘AM2301’].Temperature }}”}}, {‘sensor’: {‘name’: ‘Outside Humidity’, ‘unique_id’: ‘outside_humidity’, ‘state_topic’: ‘outside/waterheater/tele/SENSOR’, ‘unit_of_measurement’: ‘%’, ‘value_template’: “{{ value_json[‘AM2301’].Humidity }}”}}, {‘switch’: {‘name’: ‘Generator’, ‘unique_id’: … (See /config/configuration.yaml, line 443).

Can you confirm it definitely works for you? I’m convinced either the docs are incorrect or I have a magic different version that nobody else does? What is happening?

Which was built from the docs, however, here’s an interesting thing… it looks like they changed the YAML for MQTT.

I suspect you’re not on 2023.8.
