💬 Building a Raspberry Pi Gateway

[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

what means "5VReg -> 3.3V" in raspberry? can connect directly to 3.3V or if requied connecto to 5V with regulator to obtain 3.3v?

Hi :) Does anybody know how to use MY_SIGNING_NODE_WHITELISTING in gateway raspbery pi? Where I must create/edit white list with my nodes?

[OliverDog]

first sorry about the basics question but I think many people have the same questions and can't find the answers:
After connecting the radio (including IRQ on 15pin) and the info LEDs to the GPIO, how to config it?

1. Do I need to configure all the info on the same command, or can I send the command "./configure --" many times for different configs?
2. Do I need to configure it as a MQTT gateway?
3. Where did the 127.0.0.1 IP come from?
4. Does MQTT use internet connection?
5. Why do you talk about Serial Gateway here, once we have a specific type for it? this type is about using GPIO only, isn't it? That is confusing!!!

[OliverDog]

trying to config on a Home Assistant Rpi.
Sorry again for the newbie questions...!!!

[Erik Tamminga]

Hi,
Can I use pin 18 (GPIO 24) on my RPi3 for IRQ usage? Should I?
If I compile with --my-rf24-irq-pin=18, no date is received when the gateway starts.
I Cannot use pin 15 because that pin is covered by my Z-wave.me board.
Regards,
Erik

@Roberto-Mo-Ca If you are using the nrf24 PA/LNA version you need to use a 5V->3.3V regulator otherwise you can connect to the 3.3v pin.

[marceloaqno]

@macvictor For the MY_SIGNING_NODE_WHITELISTING, you can uncomment and edit it in MyConfig.h or add it to the examples/mysgw.cpp.

[marceloaqno]

@OliverDog

You execute ./configure once with all your options to set your gateway.

You need to decide what type of gateway you want to build: ethernet, serial or mqtt:
https://www.mysensors.org/build/select_gateway

Take a look at the link and let me know if you still have any questions.

[OliverDog]

thaks @marceloaqno but I was wondering there was a new type of gateway named Raspberry Gateway, were we could connect the radio directly on the GPIO and config it locally, without internet, because of that I also would like to know if MQTT uses internet connection.
I actually use a serial gateway connected to Pi USG and it works without internet...
I just want to have only one device...
Thanks

[marceloaqno]

@OliverDog You can configure the RPi to be any of the 3 types: ethernet, serial or mqtt, with the nrf24 attached to it.

[OliverDog]

@marceloaqno WOWWW
now I understood... but I think this is not clear on the build steps...
I choose a Serial Gateway, but on that lines, they say:
"If for some reason you can't use the GPIO pins of the Raspberry Pi, you could connect the radio to a arduino with the GatewaySerial sketch and feed the pi through a serial port:"

So I assumed the serial gateway is the same I already use...
So, where do I get directions to config a serial gateway with the radio attached to the GPIO?

Thanks

[marceloaqno]

@OliverDog Which controller are you using(or are planning to use)?

[marceloaqno]

@Erik-Tamminga Some pins may have some restrictions, I couldn't find any good info about that. Try using another pin (GPIO 25).

[OliverDog]

@marceloaqno I already use Home Assistant with a Serial Gateway connected on pi USB.

[marceloaqno]

@OliverDog Home Assistant supports ethernet gateways, I recommend you go with that.

./configure --my-gateway=ethernet --my-transport=nrf24

(The default settings is to use ethernet and nrf24, so you could omit them)

and add to it any of your custom options.

I have a question regarding the --my-serial-groupname option: since I start the gateway under an user account with sudo, the gateway device ([EDIT] symlink) will be created with ownership root:root. Shouldn't it be created with root:dialout (as I chose dialout as group in my case)?

[DELETED]

[marceloaqno]

@Madhias /dev/pts/2 it's the one who holds the specified group ownership

[Madhias]

@marceloaqno OK, many thanks for that hint!

I was wrong from the beginning on, since I thought my configuration for the gateway was correct because of --my-serial-groupname=dialout - but that was not compiled. I edited now the mysgw.cpp manually (there was tty instead of dialout; and of course there was all the time the warning when compiling...). Now it works! Without chmod, or chowning anything later!
