Hi chiccio,
I gave MQTT.LWT a try and sometimes it works and sometimes not.
The broker ist producing error messages...
Any ideas? My test code.

Ret = MQTT.SETUP("mqtt://192.168.178.38")
Ret = MQTT.CONNECT("", "")
pause 300
Ret = MQTT.PUBLISH("annex/88", DATE$ + "-" + TIME$)
Ret = MQTT.PUBLISH("annex/88/LWT", "Online")
Ret = MQTT.LWT("annex/88/LWT", "Offline", 1, 1)
Ret = MQTT.SUBSCRIBE("annex/88/cmnd")
wait

sorry, forgot screenshot.

try to put MQTT.LWT before MQTT.CONNECT because it is required before the connection is done (it is sent during the connection phase)

Thank you, this seems to work. By this I can easily check if a divice ist offline by checking the broker messages.
My broker is still sending wierd messages about differen annex-devices. Is there a way I get to know which device is ment by

annex_xxxxxxxxxx ?

this could probably solve Problems with mqtt communication. Does a device send an indentification number?
thanks

You can use the 3rd optional parameter to define your ID

Thank you for your help. There are still some errors on other units (8266) and I try to figure it out.
Come back to this.
greetings...

Gentlemen,

I found out that if you connect to the WebServer of Annex basic it all runs normally and only your Station Mode connection is visible on your Router.
If you have also made a serial connection, the Ap mode connection will also be visible and if nothing has been entered in Config for Ap mode, the mac address will be displayed without a lock!
So if you do not enter anything in Ap mode and have not entered Protected Access, your neighbor can watch.
So be careful with a serial connection and always use a Name and strong password with Ap mode and also apply secure access and of course also applies to Station Mode.
This only disappears again at your Router when you have closed all serial programs and restart the ESP module without opening a serial terminal connection.
Whether this is a mistake I don't know, but people have already been warned about it?

Did I miss a .bin for the S3?

Yes, I didn't published the version or the esp32-S3.
It looks that you are the only one interested

What is the module that you have? QIO / OPI / PSRAM ?

I have this one on order ...
