Hello,

I’m rather at loss how to get a very simple text input and then send it on to a mqtt topic (json) in a Lovelace Card.

I have tried a number of solutions on the forums, just no joy, Including a blueprint.

Does someone have an example please.

Thank you

could you add a button and input text on the dashboard. have a script something like this ?

- action: mqtt.publish
    data:
      payload: |
        {{ states('input_text.xxxxxx')
      topic: topic

I don’t have anything to test with but may or may not help with what your after

Here is the card I have modified from an example I found. It looks like the payload

entities:
  - entity: input_text.message
    type: custom:text-input-row
  - action_name: Send Message
    icon: mdi:keyboard
    name: ' '
    service: mqtt.publish
    service_data:
      topic: home/pi1/test
      payload: |
        {"message": {{ states("input_text.message") }} }
    type: call-service
type: entities

this produces the mqtt message (MQTT EXplorer)

It looks like the payload is not being parsed, but just passed through as a string!

Most core cards don’t support templates.

Put your publish action in a script and call that from the tap action.

Also where is this special row element documented?

I have never seen it and can’t find it in the documentation.

Try this:

entities:
  - entity: input_text.message
    type: custom:text-input-row
  - type: button
    name: Send Message
    icon: mdi:keyboard
    tap_action:
      perform_action: script.publish_my_data
type: entities

Then your script:

script:
  publish_my_data:
    sequence:
      - service: mqtt.publish
        data:
          topic: home/pi1/test
          payload: >
            {"message": {{ states("input_text.message") }} }

Should be:

tap_action:
  action: perform-action
  perform_action: script.publish_my_data
