💬 Building a Raspberry Pi Gateway

gohan

Voltage regulator is strongly suggested when you are going to have the gw sending out messages and also a bigger capacitor will help

Andy Pethan

I'm trying to understand the need for a separate Gateway if the Ras Pi is the host of the controller. Is it possible to use OpenHab on the Pi AND have the RF transceiver connected to that same Pi and skip the ethernet adapter w/ Arduinos? Or, if you have to use ethernet, could you use localhost as the IP? Or is there a technical reason why that wouldn't work (or would work, but in a totally different way)? Thank you.

gohan

Did you read the article?

@Andy-Pethan there is no need, where You read that ? I have a raspi with openhab and mqtt gw on single board. works very well.

Andy Pethan

@gohan @rozpruwacz After reading a couple times it still wasn't clear that everything could run on one device (single Ras Pi), though that seemed like the intuitive answer. Thank you for confirming as I buy up parts.

Andy Pethan

I figured out my problem -- I had the image and concept of this tutorial (http://www.instructables.com/id/Uber-Home-Automation-w-Arduino-Pi/) one tab over and never noticed at 3am that I mentally blended the articles. Sorry, everyone.

gohan

In fact I was wondering what in the article wasn't clear.

Going crazy here.
I did get success with MySensors and first Arduino node on a fresh Raspbian (last image) and branch development. All ok!

Now I want re-do on other SD (same Pi, same WIring, same Radio). I did put "old" sd on a secure location and re-start from scratch.

I did compile with:

./configure --my-transport=nrf24 --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSB020

and answer is:

[SECTION] Detecting target machine.
  [OK] machine detected: SoC=BCM2835, Type=rpi1, CPU=armv6l.
[SECTION] Detecting SPI driver.
  [OK] SPI driver detected:BCM.
[SECTION] Detecting init system.
  [OK] init system detected: systemd.
[SECTION] Saving configuration.
[SECTION] Cleaning previous builds.
[OK] Finished.

Make ends with no error.

The debug

sudo ./bin/mysgw –d

locks here:

mysgw: Starting gateway...
mysgw: Protocol version - 2.2.0-beta

And no other lines.

I Repeat, same PI, same Radio, same wiring. If I try other SD, all goes ok and I can use it on domoticz.

Thank you

OK, re-re-done on fresh install and all went ok.

I think that problem was when I deleted the PI default user and created another one.

I did follow the gordon guide: https://gordonlesti.com/change-default-users-on-raspberry-pi/

Probably a permission issues changing or not changing root?

Thank you

Hi all

Hope someone can help MySensors noob :) I try to do Raspberry pi 3 gateway with nrf24 module.

Hardware:
Raspberry pi 3
nrf24 module
3.3v 0.5A regulator.
status leds (3pcs)
Domoticz Beta

I start with this instructions:
https://www.mysensors.org/build/raspberry#improving-throughput-for-nrf24

commands what i use:
git clone https://github.com/mysensors/MySensors.git --branch master
cd MySensors
./configure --my-transport=nrf24
./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway (try ttyUSBMySensorsGateway too, but now help)
./configure --my-transport=nrf24 --my-rf24-irq-pin=15
./configure --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18

make
sudo ./bin/mysgw -d

After that i get error what is same to that instruction site:

I douple check wiring that seems to be all right. I think Linux console tell wrong wiring, if wiring is problem? But anyway i douple checked that wiring.

Hope someone can help me with this problem.

I try many times different settings, dont know do i need delete some old files or can i try again and again do configure and give "make" command.

@lassivv please don't post the same question in multiple places. Posting in multiple places will result in people trying to help you in one place, even after the problem has been solved in the other place. That is a waste of people's time.

Anyone trying to help @lassivv please post in https://forum.mysensors.org/topic/7050/multi-node-project-mysensors-noob-raspberry-gateway-problem

Sorry see this topic after i post my own topic, thinks this is better topic to my problems. But i continue my own topic.

I have a couple of nodes + PI working without issues from a couple of days.
Now, I would add encryption / signing / security etc to protect traffic between Arduinos and PI.
Could you please help me posting right configuration to add to the

./configure

command?

Thank you very much!

OliverDog

Why do Tx and Rx Leds blink every 5 to 6 seconds?

Is it about communication between RPi and Gateway?

Is there a way to disable it and keep blinks only with nodes communication?

Sorry..... I would UP! this :)

Anticimex

@sineverba is there not a --help argument to get a list of settings?

sineverba

@Anticimex sure... Bit I did read also the guide and .... I did noto understand very well whats I need to activate (if need) on gateway and on Arduinos to block, for example, the persone that live on third floor to play with my heater ..... :-) thank you in advance

PS security only software, no other hardware implied / want use

Thank you!

Anticimex

@sineverba I am not sure I understand what you want. You want to enable signing? There is extensive documentation on how to enable that. As for what to pass to the configure command on a rPi I am unsure of the exact naming but I am pretty sure the names are very similar to the #define:s the signing documentation describes.

sineverba

@Anticimex Yes, the doc is ... maybe ... too extensive :)

By the way, I would signing. So I need to do on both? Gateway/Raspberry and Arduino?

Thank you

Anticimex

@sineverba I am not sure I understand how it can be too excessive? It sounds like it is inadequate since you still have questions. :)
Of course you have to enable signing on both node and gateway. You also need to personalize the services with a hmac key. This is described. Please read the docs carefully. And if they are unclear, please provide a link to the documentation you have read, so I can verify you read the correct one.
