Thanks for clarifying, @mfalkvidd, so that means that I won't use the Ethernet GW, but only the MQTT GW configuration, changing it to

./configure --my-gateway=mqtt --my-controller-ip-address=192.168.X.BB --my-transport=rfm69 --my-rfm69-frequency=433 --my-is-rfm69hw --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mymqttgateway1

Where <MQTT / MySensors GW IP address> is the MySensors RPI IP address.

But that also means that in Home-Assistant I will need to change the configuration yaml file and take out the Ethernet GW reference:

So from

mysensors:
  gateways:
    - device: '192.168.X.BB'
      persistence_file: 'mysensors3.json'
      tcp_port: 5003
    - device: mqtt
      persistence_file: 'mysensors1.json'
      topic_in_prefix: 'mysensors-out'
      topic_out_prefix: 'mysensors-in'
  optimistic: false
  persistence: true
  retain: true
  version: '2.0'

to

mysensors:
  gateways:
    - device: mqtt
      persistence_file: 'mysensors1.json'
      topic_in_prefix: 'mysensors-out'
      topic_out_prefix: 'mysensors-in'
  optimistic: false
  persistence: true
  retain: true
  version: '2.0'

But how will Home-Assistant now know what the IP address is for the MySensors RPI gateway?

Apologies if I completely missing something obvious....

@mfalkvidd Many thanks for your quick and helpful reply! Could I ask you two more clarifying questions:

• So if define the rpi as a mqtt gateway, can I see this mqtt GW still as my GW for my RFM69 sensors?
• Or do I need to split out the ethernet GW for my RFM69 sensors from the mqtt GW?

Hi all,
I am trying to use a RPI as mysensors' gateway for both MQTT as well as RFM69 and connected to network using ethernet. As controller I am using HomeAssistant. Is it possible to run a MQTT broker like mosquito on this gateway / or on a device other than the controller?

It looks like the assumption is that the MQTT broker is on the same device as the Controller:
https://www.mysensors.org/apidocs/group__RaspberryPiGateway.html:
MySensors options:

--my-controller-url-address=<URL>
                            Controller or MQTT broker url.
--my-controller-ip-address=<IP>
                            Controller or MQTT broker ip.

But maybe I misunderstand.

I was trying to use the following:

./configure --my-gateway=ethernet --my-controller-ip-address=<HomeAssistant IP>  --my-transport=rfm69 --my-rfm69-frequency=433 --my-is-rfm69hw --my-gateway=mqtt --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1

Where <HomeAssistant IP> is 192.168.XX.AA in my picture

But that doesn't allow me to specify the MQTT broker on a different device than the Controller/Home Assistant...

Perhaps I got this all wrong?

Hi all, I have a real beginner question and struggling to understand how the different components work together using the info on Mysensor.org just from a concept perspective. I am trying to build an architecture where I use Home Assistant as a controller to use MQTT sensors via RFM69 radio. So I think I need a MQTT gateway, and a RFM69 Gateway, as well as sensors connected to RFM69 radio. I have seen the description of both the MQTT gateway, as well as the RFM69 Gateway:

• MQTT Gateway: https://www.mysensors.org/build/mqtt_gateway which seems a combination of ethernet GW with MQTT client
• RFM69 Gateway: https://www.mysensors.org/build/connect_radio which seems a serial gateway(?) with RFM69 radio (but I might be mistaken) -> how does this talk to the MQTT gateway? Does it need to be combined with an ethernet GW?

I have seen other architectures (other websites) where the RFM gateway is combined with the MQTT gateway, which I can understand. I am struggling to see how the Controller (Home Assistant) communicates with the sensors using MQTT via RFM69 radio but I must be missing something obvious...
