[CLOSED] Getting crazy with MQTT

SKAL · March 27, 2020, 12:32pm

Hi all, I’m trying to configure my mqtt part on my system.
Actually i’m runnig a home assistant ( 0.107.7) on a raspbian server (buster).
I’ve installed Mosquitto broker (5.1) with the following configuration:

logins:
  - username: XXXX
    password: YYYY
anonymous: false
customize:
  active: false
  folder: mosquitto
certfile: fullchain.pem
keyfile: privkey.pem
require_certificate: false

I’ve created a user XXXX in the configuration > users with adminstrator grants, and I’ve activate the mqtt integration as mqtt broker

On the other side I have a tasmota device which is up and running on my network (I can ping it from the server)
in the configuration I inserted all the mqtt part, but if I go in the console, I get the following message:

13:30:24 MQT: Attempting connection...
13:30:24 MQT: Connect failed to 192.168.1.10:1883, rc -2. Retry in 10 sec

Do I miss something?

Ah, BTW I’ve also installed the tasmoadmin on my server, and it sees well the devices and I can interact with them!

Could you help me pls

First test : see if your mqtt is configured right.

Go to developer tools -> mqtt
under listen to a topic, enter # and click start listening
now under publish a packet, enter what is in the image and click publish

Do you see any reply in the screen ?

SKAL · March 27, 2020, 1:14pm

This is what I get

Message 0 received on tele/tasmotacucina/LWT at 2:13 PM:

That is not the message from the test, but a message from your tasmota device. So clearly your tasmota device connects.

SKAL · March 27, 2020, 1:19pm

but on the console of this device I continue to get the following message

14:18:02 MQT: Connect failed to 192.168.1.10:1883, rc -2. Retry in 10 sec
14:18:02 UPP: Multicast (re)joined

and also I can add that, nothing appeared on the MQTT part even if it is still litening

I’ve also stoped and started the listening part and I get just a multitude of

But nothing on the console of the tasmota device ?!?!?!

francisp · March 27, 2020, 1:24pm

Multicast rejoined ?

I hope you did enter the ip of your mqtt broker, and not some mDNS name.

francisp · March 27, 2020, 1:25pm

What do you expect to see on the console ? Your tasmota is sending tele messages, so it is connected.

This I see on one of my consoles :

This is my configuration on the tasmota device.

On the console I don’t expect to recive

14:27:34 MQT: Connect failed to 192.168.1.10:1883, rc -2. Retry in 10 sec

But a connection establieshed (or something like this)
and find in the mosquito brocker log something like


1585303369: New connection from 172.30.32.1 on port 1883.
1585303369: New client connected from 172.30.32.1 as auto-DB605836-EE54-A07F-1581-382937132F8F (p2, c1, k60, u'homeassistant').
1585303852: Saving in-memory database to /data/mosquitto.db.
1585305653: Saving in-memory database to /data/mosquitto.db.

but with the IP of my tasmota device

francisp · March 27, 2020, 1:33pm

Try this one :

in the tasmota console, enter Setoption19 1 and see if HA finds your device. It should, because clearly there is a connection.

SKAL · March 27, 2020, 1:37pm

the device restarted, but…

francisp · March 27, 2020, 1:53pm

Do you see the device in HA ?

SKAL · March 27, 2020, 1:56pm

not here and not in the devices list or in the entities…

this is why I’m getting crazy :’-(

francisp · March 27, 2020, 2:06pm

You see tele/ messages passing by, but the rest does not work…

Googling on “tasmota Multicast (re)joined” seems to lead to 2 problems/solutions :

bad flash, could be repaired by flashing again
problems with the Wifi connection, could be repaired by rebooting your router.

SKAL · March 27, 2020, 2:07pm

ok, I will try to reinstall everything from scratch. thank you anyway .

francisp · March 27, 2020, 2:09pm

If your going to flash again, try 8.2

SKAL · March 27, 2020, 2:42pm

I hate IT, I’ve reinstalled everything, with the same config, and now it works ;-(

thank you @francisp for your support anyway

francisp · March 27, 2020, 2:44pm

Don’t tell that to someone who worked in IT for over 25 years

SKAL · March 27, 2020, 2:47pm

you mean like I did?

Mutt · March 27, 2020, 3:08pm

I usually find that happens when you stick your tongue out to the right whilst installing, rather than the left.
