Mqtt Sensor but on diferent file than config.yaml

Configuration
,
1

After updating my Home Assistant core, the old mqtt syntax will be deprecated, so i need to move to the new one.

My old config was in this configuration:

switch:
  - platform: mqtt
    state_topic: 'bla bla bla'
light:
  - platform: mqtt
    state_topic: 'bla bla bla'

sensor: !include sensors.yaml

Here on a different file (sensors.yaml)

#Here is directly, no need to put "sensors: at the top" (this line is not readed)
  - platform: mqtt
    state_topic: 'bla bla bla'

On my case i have a lot of sensors with mqtt, wich i dont want to add it on my config.yaml, otherwise i will create a very large file.

On my case i have updated the swtches and lights on this way

mqtt:
  switch:
    - name: "bla bla bla"
      state_topic: "bla bla bla"
  light:
    - name: "bla bla bla"
      state_topic: "bla bla bla"

#And here is my issue, how i include the sensors.yaml file under that chain

Hope you guys could help me, thanks in advance

mqtt:
  sensor: !include sensors.yaml

should work (assuming you updated the MQTT sensors to the new config format)

Clever, thank you very much!

Finally got it with this syntax

mqtt:
  switch:
    - name: "bla bla bla"
      state_topic: "bla bla bla"
  light:
    - name: "bla bla bla"
      state_topic: "bla bla bla"
  sensor: !include sensors.yaml

On the file sensors.yaml i continue with my sensor list (obviusly with the new format).
