MQTT binding with cloudmqtt

[jasondreher]

I cant seem to get MQTT working with a cloud broker, as I understand I do not need a broker like Mosquitto as I am using the cloud…

my mqtt.cfg is…
cloudmqtt.url=tcp://m10.cloudmqtt.com:xxxxx
cloudmqtt.clientId=smartthings
cloudmqtt.user=xxxxx
cloudmqtt.pwd=xxxxx
cloudmqtt.qos=1
cloudmqtt.retain=true
cloudmqtt.async=false

And I am getting my port and login info from my account at https://api.cloudmqtt.com.

But I am getting errors on the log screen

2018-06-13 14:38:02.001 [INFO ] [t.mqtt.internal.MqttBrokerConnection] - Starting MQTT broker connection 'cloudmqtt'

2018-06-13 14:38:02.285 [ERROR] [penhab.io.transport.mqtt.MqttService] - Error starting broker connection

org.eclipse.paho.client.mqttv3.MqttException: MqttException

	at org.eclipse.paho.client.mqttv3.internal.ExceptionHelper.createMqttException(ExceptionHelper.java:38) [226:org.openhab.io.transport.mqtt:1.12.0]

	at org.eclipse.paho.client.mqttv3.internal.ClientComms$ConnectBG.run(ClientComms.java:664) [226:org.openhab.io.transport.mqtt:1.12.0]

What Do I need to do to fix this?
I have tried ssl, a different login (the user login) and different ports mentioned in other posts but nothing works.

MQTT Binding and SSL

MQTT Binding and SSL Purpose Until the MQTT binding 2.0 comes along, we have to do with the 1.9 version. Unfortunately this binding, despite having the ssl option is not able to implement it. I will show how to create your own ssl certificate and key, how to use keytool to create a keystore and a truststore for private and public keys for Java and finally how to modify the OpenHAB configuration to load these keys to enable ssl. Prerequisites The MQTT Binding is installed and running openHAB is …

And that was a path I tried but could not get the addtrustexternalroot.cert file. the link downloads a addtrustexternalroot.crt file when a addtrustexternalroot.cert file is what it says is needed. I was stuck at this point.

In my case, as I am using cloudMQTT, the public certificate is available for download

[rlkoshak (Rich Koshak)]

Did you try just renaming the file using .crt? There really is nothing magical about the file extension.

[jasondreher]

yes, i used the crt file downloaded, ran the rest od the instructions and i was able to finish that, but i still have errors with mqtt and cannot get it going.

Can I see your mqtt.cfg please?

[jasondreher]

my mqtt.cfg is…
cloudmqtt.url=ssl://m10.cloudmqtt.com:13958
cloudmqtt.clientId=smartthings
cloudmqtt.user=xxxxx
cloudmqtt.pwd=xxxxx
cloudmqtt.qos=1
cloudmqtt.retain=true
cloudmqtt.async=false

[vzorglub (Vincent Regaud)]

@jasondreher

cloudmqtt.url=ssl://m10.cloudmqtt.com:13958

That the config given to you by cloud mqtt?

That’s mine

cloudmqtt.url=ssl://m23.cloudmqtt.com:24879

for:

cloudmqtt.user=xxxxx
cloudmqtt.pwd=xxxxx

I use exactly what cloudMQTT has given me.

[jasondreher]

Yes that is exactly what I am looking at and using but it still errors out in my :9001 log. I will just start over again with my Openhab image, I am using a raspberry pi 3b with the Openhab image, maybe a fresh start will help things. If not I will switch over to the local MQTT.

Thank you both for all your help!!!

[vzorglub (Vincent Regaud)]

It looks like the normal port start with 1 and the ssl ports are 2…
Have you tried port 23958?

[jasondreher]

I did see that, I tried the SSL port listed in my account, but no go.
