MQTT not working

[xbavnu]

I am having problems setting up MQTT with my light panels. I enabled MQTT support in the configuration before flashing the software and it is also enabled and configured in the settings in the web interface. I can control the lighs via HTTP requests but I am unable to use them with alexa or home assistant.

The MQTT log is flooded with these messages: 1646414788: Socket error on client Nanoleaf, disconnecting. 1646414798: New connection from 192.168.178.25 on port 1883. 1646414798: New client connected from 192.168.178.25 as Nanoleaf (p2, c1, k10, u'mqtt-user').

Here is a picture of my MQTT configuration on the web interface:

What am I missing or what could be the problem here?

I also enabled the debugging messages on the Wemos D1 mini and this is a snippet with all the messages that are repeating all the time:

Everything seems good with your setup and log, it might just be the autodiscovery feature on HA that might be off, try enabling it

Thank you for the response. Auto discovery is enabled and works just fine with other MQTT devices running tasmota.

In the home assistant MQTT log I still have these messages popping up every couple seconds: 1646414788: Socket error on client Nanoleaf, disconnecting. 1646414798: New connection from 192.168.178.25 on port 1883. 1646414798: New client connected from 192.168.178.25 as Nanoleaf (p2, c1, k10, u'mqtt-user').

So it seems like the ESP is connecting and disconnecting all the time.

I had a similar issue (see issue #206 ). Using strlcpy instead of strlcat, on line 1432 fixed the issue where the esp would continuously try to reconnect.

@Brackus9

Thank you very much! It seems like this fixed all the problems. I can now use both, Alexa and MQTT to control the lights.

@Brackus9 would you mind submitting a PR with that change please?
