Use single topic for MQTT client status (LWT, birth, etc.)

Thanks, @rejoe2!

Tell me how to useLWT. Because messages must be 2. The first is entered into the broker when connected with an indication of the topic, and the second is periodically sent to the broker for a status condition. Is it possible to use a separate topic (milight/states/LWT) for LWT or should it be combined with any of the other topics?

[odis68]

The module is connected and active!

[rejoe2]

Are you using latest version (1.9.0-rc3)?

[odis68]

Sorry for an example from another project. This is not disrespectful but for example only.

Yes, I have installed latest version (1.9.0-rc3)

[sidoh]

@odis68, the name of the setting changed. It's now mqtt_client_status_topic. You'll need to reconfigure it.

[sidoh]

Guessing the data on your status/LWT topic is a left over retained message.

[odis68]

[sidoh]

That is not RC3. Looks like RC2 or earlier. RC3 here:

https://github.com/sidoh/esp8266_milight_hub/releases/tag/1.9.0-rc3

r. RC3
I cleared the topic (milight/states/LWT) by entering an empty value but after resetting the same value.

[sidoh]

The UI is definitely from RC2.

Can you maybe try force-refreshing? Perhaps the UI got cached by the browser or something.

[odis68]

You were right!!! The problem in the browser helped clear the cache !! Thank you very much you have fulfilled several trials at once.
