[TEST-A] Controller Homie can not connect to mosquitto MQTT broker

DynamicLoader commented 2 years ago

Summarize of the problem/feature request

Hi, I flashed ESP_Easy_mega_20211224_test_A_ESP8266_4M1M.bin to my ESP8266 (Wemos D1),and I want to use the plugin Homie MQTT. But I can't get it connect to Mosquitto MQTT broker running on my RasPi. All the things are correct.The same MQTT connection settings goes well with Domoticz MQTT and openHAB MQTT.

Expected behavior

ESP8266 Homie MQTT connect to broker successfully.

Actual behavior

On the brokers log,I found:

Mosquitto[169553]: 1643727806: New connection from {ESP8266 IP} on port 1883.
Mosquitto[169553]: 1643727806: Bad socket read/write on client <unknown>: Invalid arguments provided.

On the ESP8266 serial port log,I found:

496698 : Error  : MQTT : Intentional reconnect
511738 : Error  : MQTT : Broker C014 connection failed (6/0)

Steps to reproduce

Add Homie MQTT controller and set USE IP address,enter IP and port,then tick Enabled, Submit.

System configuration

Hardware: ESP8266

ESP Easy version: 20211224_test_A

ESP Easy settings/screenshots: None

Thanks.

Can you test to see if any other MQTT controller is able to connect? For example the OpenHAB MQTT controller.

If your MQTT broker requires credentials, what length have those? Please also test with "use extended credentials" checked.

DynamicLoader commented 2 years ago

To simplify the debug,I have configured the mosquitto server not to use any credential,and no ssl. The same config on esp8266 goes well with Domoticz MQTT and openHAB MQTT plugin.I think the problem is the Homie plugin itself.

Thanks for reply.

@Lucy2003 how long is your login/password?

DynamicLoader commented 2 years ago

@uzi18 I have NO login and NO password.Anonymous connection is allowed on the broker.

OK, if the other MQTT controllers can connect to the broker, then it is indeed something specific to the Homie controller. Have you tested/used it before? And if so, if you did, what version was working?

DynamicLoader commented 2 years ago

To be honest,this is my first try.

My workaround which is not useful at all is like this...

connect to broker.hivemq.com:1883
check if it is connected on main page
after it is connected, change MQTT parameters to your Mosquitto broker
it will be connected but it suffers from random disconnections
if it stops working, repeat steps

I was banging my head last month over this and I feel exhausted :D does previous version works as it should ? :D will try it out...

Make sure to set the timeout to 1000 msec. Also, how do you address your broker? Via IP or via hostname? (your local broker)

mekintos commented 2 years ago

To connect to broker.hivemq.com:1883 I use Locate Controller: Use Hostname
and after successful connection I change to -> Locate Controller: Use IP address and 192.168.0.5 for my IP where is broker installed...

after this, it works usually till next reboot when I have to make these changes again...

some of the previous builds worked without any issue... I flashed newest one and it has this problem now :D sad thing is that I don't remember which version worked for me

Please show the controller settings you are using. And also, is the MQTT broker running on the same subnet of your network as the ESP?
