💬 Building a Raspberry Pi Gateway

[Sebex]

@mfalkvidd thanks, I was wrongly under the impression that sudo mysgw would show the logs but it creates a second instance. Thanks for helping :smile:!

I have an Arduino Mesh network (see https://tmrh20.github.io/RF24Mesh/) (master and 4 nodes)
networkChannel 120, networkDataRate RF24_1MBPS, nodes 0-4

Now I want to have my master be an RPi because it can talk to the real world.

It looks like I have the RPi wired up and software loaded (per https://www.mysensors.org/build/raspberry). Now I need to know how to talk to my Arduino's.

Now how do I talk to my Arduino's?

o- general description of what you are trying to do
Raspberry Pi controller with serial gateway with nrf24l01+ to connect to Arduino's
o- the exact configure command you used
git clone https://github.com/mysensors/MySensors.git --branch master
cd MySensors
./configure --my-transport=rf24 --my-gateway=serial --my-serial-is-pty --my-serial-port=/dev/ttyMySensorsGateway
make
sudo ./bin/mysgw
[reboot RPi]
cd MySensors
sudo make install
sudo systemctl enable mysgw.service
sudo systemctl start mysgw.service
ls -als /dev/ttyMySensorsGateway [yeilds: 0 lrwxrwxrwx 1 root root 10 Apr 9 19:22 /dev/ttyMySensorsGateway -> /dev/pts/1]

@OldSurferDude if you want your nodes to use MySensors, you'll need to upload MySensors sketches to them.

hi i am trying to install an MQTT type gateway on a raspberry pi 3,
 
I configured it as in the example:

./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

Then I do make and it does not generate errors.

and when i run

sudo mysgw

returns the following result, I do not understand what it can be or what it means.

Apr 10 15:12:21 DEBUG connected to 127.0.0.1
Apr 10 15:12:22 DEBUG! GWT: RMQ: FAIL
Apr 10 15:12:22 DEBUG GWT: RMQ: CONNECTING ...
Apr 10 15:12:22 DEBUG connected to 127.0.0.1
Apr 10 15:12:23 DEBUG! GWT: RMQ: FAIL
Apr 10 15:12:23 DEBUG GWT: RMQ: CONNECTING ...
Apr 10 15:12:23 DEBUG connected to 127.0.0.1

I appreciate your time to explain this to me please, I am just starting to use Mysensors and it is incredible everything that can be generated.

Also I want to connect it to Mycontrroller.org to manage my devices from my sensor network with only 1 Gateway, I already downloaded it in my RPI3 and it runs fine, but when I connect or create the mqtt type gateway, it asks me for the broker host and I do not know what to put there, I thought of 127.0.0.1, but after that it tells me that the State is down and an error message with the IP of 127.0.0.1 and I do not know then that I need this. Thanks again for your time to explain this to you.

You're not being able to connect to your MQTT broker (Mosquitto or Moqutte as was in mycontroller.org). I havent used mycontroller so I cant help with that.

I use Mosquitto on the same Rpi (so just install mosquitto and mosquitto-clients). You should secure it but test first without credentials to get going. Remember to create credentials in mosquitto AND reconfig your gw

[Nicolás Potier]

@MasMat I already managed to configure my gateway it already works with Mycontroller.org, I like the interface of this, but I was thinking if the nodes of my network, which are esp8266 can be configured an operating system like FreeRTOS, TinyOS or ApacHE MyNewt can be configured in my osp and handle all Mysensors processes?
There is a possibility or it is impossible

[MasMat]

@Nicolás-Potier that's way way over my understanding and fluency with Mysensors. And way off topic, I think.

[rafal9318]

Hi all,

I want to launch gateway on RaspberryPi with a RS485 network.
I downloaded the software (MySensors Library v2.4.0-alpha).
And i made coniguration:
./configure --my-transport=rs485 --my-rs485-serial-port=/dev/ttyUSB0 --my-rs485-baudrate=9600 --my-gateway=serial --my-serial-is-pty --my-serial-port=/dev/ttyUSB20 -my-serial-baudrate=115200 -my-serial-groupname=tty

I have USB-RS485 (it uses FT232RL) converter connected to the /dev/ttyUSB0.
On the other side i have Arduino uno with UART-RS485 (MAX485) converter, and a MotionSensorRS485 example on it.

After i made the program (make), and type sudo ./bin/mysgw, i've got this:

I'm able to add the hardware in domoticz (serial gateway ttyYSB20, 115200), but it doesn't see nodes.

Please help.

[mfalkvidd]

@rafal9318 please don't post the same question in multiple threads. Posting in multiple threads means the discussion is split. Important information might be available in one thread, but not the other, which means people have to ask you for that information multiple times. It is a waste of the community members' (including you) time.

If anyone can help @rafal9318 please respond in https://forum.mysensors.org/topic/11128/raspberrypi-4-as-a-gateway-controller

[rafal9318]

@mfalkvidd Okey, sorry.

[ej3-martin]

I’m sorry if this is a newbie question. I have managed to create a controller using MyController on a Raspberry Pi. I have connected a NRF24l01 and created a gateway, and my controller picks up that I have a gateway present, so I assume my wiring is correct.
I have started to wire up the status LEDs, and this is where I am confused. I am used to using LEDs on PI, but connecting between he GPIO pin and ground, where the GPIO provides the voltage. The diagram above suggests that they should be permanently connected to the voltage and the GPIO provides the ground connection. Is this correct? And if it is, is it possible to test the LEDs? Thanks in advance.

[MasMat]

@ej3-martin My LEDs come on when the Rpi boots (is that what you mean by testing?). Also you can invert the LEDs (on but blink off) if you want. I figured the wiring makes for better power delivery rather than feeding voltage from the GPIO

[ej3-martin]

@MasMat I was purely wanting to find a way of testing them, to check my wiring, if they do come on during boot then this is a great way to test. It would also possibly be useful (for those of us less experienced) to have a script to run to check the wiring is correct. I think it much more useful to have them off, and blink on, and it was the wiring that confused me. I will have to see if I can investigate this further.

[mfalkvidd]

Since the pins are configurable before compilation, creating a script that uses the same settings as the compiled code would be pretty hard.

The easiest way with existing code is probably to add --my-leds-blinking-inverse to your configure command and start the gateway, as suggested by @MasMat

[Fear na Boinne]

Just trying to figure out whether there is a switch or config file option for the channel, or whether the only option to change the channel is truly to recompile?!...

Just ran the Poor Man's scanner and channels 1-98 a a garbage mess, so I need to go >> 100, but am surprised the only option there seems to be a recompile?...

[mfalkvidd]

@Fear-na-Boinne yes that is correct

[Fear na Boinne]

Sorry for the lack of response, life's been crazy... Thanks for the reply, I have since recompiled, but need to make some add'l changes to the sensor sketches, so I want to do all of that at once before I deploy to the new channel... ;)

[mfalkvidd]

@Fear-na-Boinne if you want to be able to switch your rpi gateway between the old and the new channel while testing, you could try my patch which allows configurable service name

https://github.com/mysensors/MySensors/pull/1421

Or just skip running make install so you don’t overwrite the old gateway

[Fear na Boinne]

@mfalkvidd Just a quick update...

Been extremely busy, so not a lot of time, but when I run the recompiled version (channel 109) gateway and use the existing - known good - sensor sketches with the channel 109 macro declaration included, it doesn't connect at all.
When I run the "old" version of the gateway and the same sensor sketches with channel 109 commented out, it just-works™...

More testing and such due I guess! :(

[hawtcher]

Is it possible to have the RPi4B, that is being used as the Webthings Gateway, also be the My Sensor controller once I add a NRF24L01+ module and follow steps above?
