MQTT Gateway Configuration

[Soloam]

Hello all, a quick but important question. When we add a new mqtt gateway, I get several fields, please confirm:

QoS: << Zero? Or should I use 1? >>
Broker host: << The Broker That The MQTT Gateway is pointing to. MY_CONTROLLER_IP_ADDRESS variable >>
Client id: <<The Gateway ID? Or A Id to The Controller?>>
Topic publish: << MY_MQTT_SUBSCRIBE_TOPIC_PREFIX variable from gateway >>
Topic subscribe: << MY_MQTT_PUBLISH_TOPIC_PREFIX variable from gateway >>

I've been having some problems with the controller and MQTT, and I was wondering if it's some miss configuration

Using https://www.mysensors.org/build/mqtt_gateway as reference

Thank You

QoS: where did you find this? I was unable to find it on the gateway page you linked to, and the MySensors source code does not seem to use it.
Broker host: this is not mentioned on the gateway page either. Where did you find it?
Client id: this is an id for the gateway, to make it different if you have multiple mqtt gateways.
Topic publish, Topic subscribe: These set which topics the gateway should post messages to and read messages from.

I think I dind't explain myself proprely, sorry, probably lost in translation.

I was talking about MyController gateway configuration:

The Fields on the screen:

QoS: << Zero? Or should I use 1? >>
Broker host: This Is the MQTT Broker Address?
Client id: Is this a unic name to the MyController client, or the GW Name?
Topic publish: The topics where the Mysensors GW is submitting?
Topic subscribe: The topics where the Mysensors GW is Subscribing?

Thank you

@soloam said in MQTT Gateway Configuration:

QoS: << Zero? Or should I use 1? >>

It's up to you, just Google it to see what different qos levels do, either would probably work just fine

Broker host: This Is the MQTT Broker Address?

The ip address of mqtt broker

Client id: Is this a unic name to the MyController client, or the GW Name?

Choose whatever you like, just make it unique

Topic publish: The topics where the Mysensors GW is submitting?

That is where gw is subscribed listening for data

Topic subscribe: The topics where the Mysensors GW is Subscribing?

That is where gw publishes the data

Keep in mind that mycontroller has a built-in mqtt broker, so you have to disable it if you are using it on the same computer as the other mqtt broker

Thank you for your replay. My main doubt was the client-id, I didn't understand if it was a unic name or the GW client-id. You answered my question.

Thank You for your help
