MQTT connection lost, laggy web interface, restart required about opendtu HOT 7 OPEN

First I'm going to install that latest update to see if it helps. As I'm on vacation right now this will be in 2 weeks since I need to power cycle. Maybe a short power cut might help ;-)

USB serial debugging is the next step.

Thanks!

Happened again:

I saw the unit connected to WiFi. Immediately when I initiated a "Disconnect" from my wireless infrastucture, it reconnected and was properly available.

There was no need to reboot or similar.

Have there been any changes to the WiFi code in the last release? I don't remember having had the issue before.

Lets see what happens with new 24.8.1 release, I'll let you know.
Maybe it's just a bug in the backend libs somewhere

It just happened again:

IP connection is down, no connection to wireless infrastructure...
Red LED did blink each 5 seconds, indicating that OpenDTU was still running somehow.

After resetting power, all back to normal.
Strange.

Has this been corrected with the latest version (wifi reconnect issue)?

I wonder how I can get the unit back online without being on site... hm

I think this might still be related to some MQTT buffer overload / heap fragmentation. Without further USB Serial Logs about the time the problem occurs, ie sometime before and starting to loose connection this is hard to debug.

Though the comments in #2185 by @Kroki0815 here #2185 (comment) and by @jstammi here #2185 (comment) might shed some light on your issue too.

Have you tried another esp32?
I have experienced similar effects on different projects, even with simple stuff using esphome . Effect was observed on some boards, on some not using the same firmware.
Most boards get back again when soft rebooted remotely once they appear again after short outage and run stable for a while afterwards. Some don't and need to be powered off.
I think the quality of the chips may vary too much...
