💬 Building a Raspberry Pi Gateway

[lakshmc]

I using RPi2 and NRF24 for this. I followed the instructions, to clone the repo, and then added config
./configure --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1 --my-transport=nrf24

make

when i run with sudo ./bin/mysgw -d, it is failing to connect to MQTT. Can you please help?

@Anduril

Have you aver considered Using the GatewayESP8266MQTTClient? What controller are you trying to connect?

[Anduril]

I use pimatic which does not have a native compatibility to ethernet or mqtt. Thats why my question came up on how to configure it to do this...

Building a Raspberry Pi Gateway:

If you are running a controller on the Raspberry Pi that doesn't support communication with the gateway through ethernet, you can use a virtual serial port:
./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway

[mfalkvidd]

@Anduril you might be able to use nodered or socat to convert the tcp connection to a serial port.
https://linux.die.net/man/1/socat
https://nodered.org/

[Anduril]

that's what I tried in the past and am using now (socat), but it does not reconnect and has some other drawbacks. Reading of an officially supported way sounded interesting

[pete1450]

@lakshmc Make sure you don't have the daemon running already

If not, I'm getting the same problem on the 2.1.1 that was just released. 2.1.0 was working "fine"(besides my suspecting a bug that doesn't let any inclusion happen, hence I tried the new version). Time to go back to the serial gateway right into the vera.

@pete1450 @lakshmc
Make sure you are not using an old version of mosquitto (or any other broker you're using):

$ mosquitto -h
mosquitto version 1.4.10 (build date 2016-09-20 11:02:07-0600)

It's working fine with the 2.1.1 release:

@marceloaqno I should have specified, I'm getting the connection errors with the ethernet gateway.

[marceloaqno]

@pete1450 Could you send the debug log with the connection errors?

[lakshmc]

@marceloaqno After installing broker and gateway fresh, seems to be working. Thanks for your help.

[pete1450]

@marceloaqno
Ran as root and made sure I didn't have mysgw already running:

rm -r MySensors/
git clone https://github.com/mysensors/MySensors.git --branch master
cd MySensors/
./configure --my-controller-ip-address=192.168.1.136 --my-port=5003 --my-rf24-irq-pin=15
make

root@raspberrypi:~/downloads/MySensors# ./bin/mysgw -d

every few days mysgw randomly dies :(

[marceloaqno]

@pete1450 If you use the --my-controller-ip-address= option, the gateway will act as a client and attempt to conect to the supplied ip and port. If you want the gateway to open port 5003, omit this option.

[Anduril]

@marceloaqno what is the correct configure option to make this gatway connect to an ethernet gateway and let a serial-only-controller connect to it. I suppose to use the pty option, but didn't got this working. As said above, socat and nodered are no option.

[pete1450]

@marceloaqno Well that fixed the connection issue. Now I'm just back to square one where pressing start doesn't do anything. Why do I not need to specify my controllers ip? That is the ip for my veralite. Whats the use case for that option.

[marceloaqno]

@b0rmann Could you provide the following information?

• Your RPi model and which linux distribution you are using.
• gcc version
• The version and options you used to build the gateway (./configure --option)
• The number of nodes on your network that sends messages to the gateway.
• The broker you are using for MQTT and its version

[marceloaqno]

@Anduril Sorry, the gateway does not support what you're trying to do.

[marceloaqno]

@pete1450
I can't help you with this, I've never used the Vera controller. You need to search in the Vera settings where you set this option. If Vera supports being a server and opening a port for the gateway to connect, then you use the --my-controller-ip-address option.

[Michael Curtis]

Does anyone know if the Raspberry implementation have a UserPassword option for ./configure MQTT

[Michael Curtis]

@Michael-Curtis Nevermind, I fixed it.... you ned to add :

--my-mqtt-password=<PASS>   MQTT password
--my-mqtt-client-id=<ID>    MQTT client id.

Under "cat"

And for the actual options under "opt do"

--my-mqtt-user=*)
    CPPFLAGS="-DMY_MQTT_USER=\\\"${optarg}\\\" $CPPFLAGS"
    ;;
--my-mqtt-password=*)
    CPPFLAGS="-DMY_MQTT_PASSWORD=\\\"${optarg}\\\" $CPPFLAGS"
    ;;

then just add those option flags to the ./configure and run make
