MQTT LWT disconnection

[Micha_he]

In my opinion, the newer firmware-versions disconnect from MQTT-broker before they go to deep-sleep. So the broker give no 'Connection Lost' message. Can I disable this disconnect-message befor sleep for some clients, to get the old behavior?

Hmm that's one feature I didn't think of.
I guess it makes sense to have it included.

Only thing I can't predict is if all data in the buffers of the MQTT client will be flushed when going to sleep.
That's one reason why I made sure to disconnect before sleeping.

Another approach can be to send the LWT ourself.

I'll test your suggestion to send the 'Connection Lost'-message via rule before goto sleep. But only in a few days, after my bike tour. The problem exists only at three devices, that goto deepsleep.
