MQTT error connection with Bekchertown skin

[Carlo]

Hi everyone. I have a problem with the MQTT Broker on my localhost server.

My website (meteopievedicampo.ddns.net) work good, but i wanto to enable MQTT.

I open on my firewall the 9001 port.

I have this error in mosquitto log:

-------------------------------------------------------------------------------------------

1615760009: New connection from 127.0.0.1 on port 1883.

1615760009: Client <unknown> disconnected due to protocol error.

1615760060: New client connected from ::ffff:192.168.1.2 as website557173374 (p2, c1, k60).

1615760060: New connection from 127.0.0.1 on port 1883.

1615760060: Client <unknown> disconnected due to protocol error

---------------------------------------------------------------------------------------------

and this is syslog:

---------------------------------------------------------------------------------------------

DEBUG user.mqtt: Failed upload attempt 3: [Errno 104] Connessione interrotta dal corrispondente

ERROR weewx.restx: MQTT: Failed to publish record 2021-03-14 23:18:23 CET (1615760303): Failed upload after 3 tries

---------------------------------------------------------------------------------------------

This is my weewx.conf:

---------------------------------------------------------------------------------------------

[[MQTT]]

        server_url = mqtt://carlo:XXXXXXXXX@localhost:1883/

        topic = weather/loop

        unit_system = METRIC

        binding = archive, loop

        aggregation = aggregate

         [[[tls]]]

            tls_version = tlsv12

            ca_certs = /etc/mosquitto/certs/chain.pem

 # MQTT Websockets defaults

            mqtt_websockets_enabled = 1

            mqtt_websockets_host = meteopievedicampo.ddns.net

            mqtt_websockets_port = 9001

            mqtt_websockets_ssl = 1

            mqtt_websockets_topic = weather/loop

            disconnect_live_website_visitor = 1800000

[MQTTSubscribeService]

    enable = true

    host = localhost

    port = 1883

    keepalive = 60

    username = carlo

    password = XXXXXXXXXX

    binding = loop

    [[message_callback]]

        type = json

    [[topics]]

        unit_system = METRIC

-------------------------------------------------------------------------------------------

And this is my mosquitto.conf:

------------------------------------------------------------------------------------------

persistence false

allow_anonymous true

password_file /etc/mosquitto/passwd

acl_file /etc/mosquitto/acl

# Insecure mqtt to localhost only, and secure mqtt

listener 1883 localhost

listener 8883

certfile /etc/mosquitto/certs/cert.pem

cafile /etc/mosquitto/certs/chain.pem

keyfile /etc/mosquitto/certs/privkey.pem

protocol mqtt

# websockets

listener 9001

certfile /etc/mosquitto/certs/cert.pem

cafile /etc/mosquitto/certs/chain.pem

keyfile /etc/mosquitto/certs/privkey.pem

protocol websockets

------------------------------------------------------------------------------------------------------

Thanks everyone help me!

I’ll make a wild guess and hypothesize that the problem is that the weewx MQTT module is trying to speak TLS to the broker on port 1883 rather than 8883.  I would start by getting MQTT working without TLS — just remove the “[[[tls]]]” section from weewx.conf.  Once that is working you can add TLS back, but usually there’s no advantage to encrypting network traffic to localhost.

I revome the “[[[tls]]]” section from weewx.conf and now the error disappear:

------------------------------------------------------------------------

but it doesn't work, always in "waiting data from the sation"

this is the log of mosquitto.conf

Comparing your configuration to mine, I think you should be publishing to “weather” rather than “weather/loop”  That is, in the [[MQTT]] section, set “topic = weather” instead of “topic = weather/loop".  Leave the "mqtt_websockets_topic = weather/loop” in [[Belchertown]][[[Extras]]] as-is. 

By the way, I found mosquitto_pub and mosquitto_sub (from the mosquitto-clients package) to be very useful for debugging MQTT issues.

Finally i resolve.

I remove /loop and ... now it works and my station refresh every 16 seconds.

Thanks again.
