mqtt with authentication?

[marekorok]

Hello,

is there any way to use mqtt with authentication?

I was trying tcp://login:password@server_ip:1883 but no luck mosquitto reports in logs: Client disconnected due to protocol error.

cheers

Have you tried tcp://:61616 ? That the locator for the Artemis MQTT broker

[marekorok]

well, I'm using standard mosquitto mqtt broker installed on my home assistant environment and I don't want to use anything else. Then it is using standard ports (established by IBM, mqtt inventor): 1883 for non-encrypted and 8883 for TLS encrypted traffic.

Every client I have is authenticating to the mqtt for security reasons, which I think is a standard nowadays, example Tasmota:

That is why I'm asking for such possibility...

Adding the authentication for the Artemis MQ Broker would be no problem. But you would need to bridge between Artemis MQ to Mosquitto. So you need a client connecting to Artemis MQ to receive the BMS data and a producer to post to your Mosquitto broker on a topic/queue there. Or you could have home assistant connect as a client directly to the Artemis MQ broker which would make things simpler.

I guess for the integration to HomeAssistant it would be nice to configure (possible multiple) producers to post the BMS data directly to a MQTT broker. You would then need to create a HA configuration first to map the BMS data Json to a HA sensor. At least that's how I understand. I haven't used HA myself so I'm just guessing from the HA overview about connecting MQTT devices.

don't bother with HA for the moment, leave it for later, but shortly: the integration is done through specific autodiscovery mqtt topics: https://www.home-assistant.io/integrations/mqtt/

Assuming there is standard MQTT client implementation then there should be no difference which server is used, am I right? Then I still prefer to stick with lightweight mosquitto mqtt broker and not to add another heavy software package.

Hi, I've added the support to supply a username and passwort now in the mqtt.producer configuration:

# The URL of the MQTT broker to send to
mqtt.producer.locator=tcp://127.0.0.1:61616
# The topic name on the MQTT broker to send to
mqtt.producer.topic=energystorage
# The username of the external MQTT broker to send to
mqtt.producer.username=guest
# The password on the external MQTT broker to send to
mqtt.producer.password=guest_pwd

This mqtt.producer configuration will now be used to connect to an external broker (like Mosquitto).

I will close this ticket as I haven't heard any problems
