RPI Gateway: Connect to Controller and MQTT broker with different IP addresses
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:
--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?
--my-gateway=ethernet means a TCP connection between the gateway and the controller. Only one my-gateway option should be specified. If you want to use mqtt, use only --my-gateway=mqtt
Set --my-controller-ip-address to the ip if the mqtt broker.
See the MQTT section on https://www.mysensors.org/build/raspberry#configure for more information.
@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?
@rjgmba yes it will still be gw for your rfm69 sensors, the picture to the left is correct.
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:
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'
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....
@rjgmba Home Assistant should connect to the mosquitto broker
