Hi
If I use wildcards in a subscribe can I somehow get a topic?

mqtt:
  id: my_mqtt
  on_json_message:
    - topic: ble2mqtt/#
      then:
      - lambda: |-
          if (x.containsKey("temperature")){
            ESP_LOGD("DEBUG", "Topic %s : Temperature  %.1f" , "how_to_a_get_topic?" ,(float)x["temperature"]);
          }

Hi,
I am also stumbling across that and I am wondering why there is so less information about that usecase out there!

This is my config:

mqtt:
  id: mqtt_client
  on_message:
    - topic: any/cool/topic/+
      then:
        - lambda: id(my_mqtt_topic) = **"how do I get the topic?!?"**

globals:
   - id: my_mqtt_topic
     type: std::string
     restore_value: no  # Strings cannot be saved/restored
     initial_value: '"123"'

Even without wildcards (afaik they have not been supported for long time anyway) I can not find a way to access the topic at all!

Thanks a lot in advance!

Hi,

I just wanted to bring up this question again. It has been around for some time now without any reaction…
