MQTT messages

[odroegehorn]

Hi again,
I have a question about the MQTT-messages the code is sending:

I got in my Broker:

soyosource_line1_c8c9a30bcac6:soyosource-line1/debug:.* debug
soyosource_line1_c8c9a30bcac6:soyosource-line1/binary_sensor/soyosource-line1_fan_running/state:.* state

soyosource_line1_c8c9a30bcac6:soyosource-line1/sensor/soyosource-line1_operation_status/state:.* state

These are state-requests, I guess ... so it's send out periodically (refresh-rated) to report the state. OK?

Then I got also something with "status" ...., what's that?

soyosource_line1_c8c9a30bcac6:soyosource-line1/status:.* status

And then I got a lot of .../config messages with starting homeassistant. What's that?
In the settings I have seen, that commands are issued with:
"soyosource-line1/select/soyosource-line1_operation_mode/command"
So what are the ../config topics for?

If they belong to a list of settings, that can be made, why is the device reporting them? For discovery in HA?
And if the are for config, what's the difference to .../command?
And if again, then, what are allowed parameter-values? Are they defined somewhere?

Sorry for all the questions. As I don't know HomeAssistant I need to reassemble the behaviour in FHEM.
Thanks in advance.

In ESPHome every entity has a state. The state of a temperature sensor could be 5 °C f.e. To avoid confusion I try to use the word "measurement" if I talk about sensor states. Measurements are reported periodically depending on the update_interval. You could change to update interval if you like.

The config topics are used to help Home Automation Software (especially Home Assistant) to auto-discover the ESPHome node and register an entity per topic auto-magically. If ioBroker/FHEM doesn't support this kind of auto-discovery you could disable the feature to avoid noise:

mqtt:
  broker: !secret mqtt_host
  username: !secret mqtt_username
  password: !secret mqtt_password
  id: mqtt_client
  discovery: false

The status topic is explained here: https://esphome.io/components/mqtt.html#last-will-and-birth-messages
It can be used as last will testament: https://www.hivemq.com/blog/mqtt-essentials-part-9-last-will-and-testament/

Feel free to ask more questions if I missed one of your questions already. ;-)

This can be disabled. Could you tell me the exact topic?

[syssi]

This is traffic of the logs topic and can be disabled. The status topic should report online or offline.

Is assume this is what you are looking for: esphome/issues#3047 (comment)

mqtt:
  log_topic: null

[odroegehorn]

You are right. It's the "debug" topic.
"status" topic provides online/offline, correct.

With "log-topic: null" I can disable the "debug" topic?
Would be great.
Thnx.

[syssi]

Yes. The log_topic is the debug topic as far as I know. It should by mentioned on startup.

[syssi]

I recommend to decrease the log level (to INFO or WARN) instead of removing the topic.
