💬 Building a Raspberry Pi Gateway

[gohan]

Why don't you compile it as ethernet gateway?

[engy]

@gohan Etherner Gareway is not supported by OpenHab MySensors binding.

[gohan]

Mqtt?

[engy]

@gohan I'm sorry, MQTT is not supported by OpenHab MySensors binding. Ethernet Gateway is not supported on Raspberry PI.

[marceloaqno]

@engy OpenHab2 supports mysensors serial and ethernet gateways:
https://github.com/tobof/openhab2-addons/wiki

Maybe the build guide may have given you that impression, but ethernet Gateway is supported on Raspberry PI:

./configure --my-gateway=ethernet

[keldandorin]

@gohan Solved the problem with radio...Thx

[engy]

Thank you guys for prompt reaction. Indeed, Ethernet GW works flawlessly!

[TommiP]

Hi
Is anyone else having this same problem on Rpi3?: Gateway works ok after "sudo make install" with openHAB. With "sudo ./bin/mysgw -d" I can get debug log visible and log works ok.
But if I run "sudo systemctl enable mysgw.service" after "sudo make install", debug log start showing endlessly "mysgw: accept: Bad file descriptor". So debug log function gets destroyed and it can't be used anymore. I have made several clean installations and every time this same happens.

Tommi

[marceloaqno]

@TommiP What I think is happening is that you are running two instances of the gateway.
If you need to get the debug logs, first stop the mysgw service:

sudo systemctl stop mysgw.service

[TommiP]

@marceloaqno
Ok, now I understand what happened, thanks.

Re: Building a Raspberry Pi Gateway

Silly questions, I'm a little bit confuse.
I have a serial Gateway running with arduino nano + nrf24 and a raspberry pi with domoticz on board. The link between domoticz & Gateway is done via USB <=> serial port (/dev/ttyUSB0). This setup runs like a charm.

Now, I would like to access to my Gateway via the network because I would like to use "Over The Air " functionnality with MYSController.

Can I install MySensors Gateway on the raspberry and keep the arduino + nrf24 connected via usb ?? For the moment, I can not use GPIO port.

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:

./configure --my-gateway=serial --my-serial-port=/dev/ttyUSB0 --my-serial-baudrate=115200

Where is my mistake ??
Again, Can I install MySensors Gateway on the raspberry and keep the arduino + nrf24 connected via usb or I must connected the nrf24 directly with GPIO on the Rasp ??

Thanks in advance for your reply.
Romeo

[gohan]

@romeo01 I think that connecting nrf24 directly to arduino and compile mysgw as ethernet gateway is the cleanest solution (I have it as MQTT and it is working fine, but ethernet is the same). Keep in mind that you'd better use one of those adapters 5v-3.3v for nrf24 chips + capacitor because the 3v output of raspberry isn't very suited for the task.

[romeo01]

Thanks gohan for fast answer.

Arduino nano + nrf24 are already connected together. Hardware is already built.

How access to the gatway installed on the raspberry via the network and use my arduino + nrf24 connected via usb/serial to the raspberry ??

Sorry but I do not understand what you mean
...compile mysgw as ethernet gateway is the cleanest solution...

If I configure on this way
./configure --my-gateway=ethernet --my-port=5003

I could access to my Gateway via network an the Gateway will use the arduino + nrf24l via usb/serial ??

That's why I say I'm confuse.

--my-gateway=serial 

What is this option ? The link between gateway and nrf24 or the way to access to the Gateway ??

[romeo01]

In summary,

Is the Gateway (software) installed on the raspberry, is able to manage the nrf24 connected on arduino via USB/Serial port ??

[gohan]

no, I don't think so. If you want to manage nodes over network you need to make an ethernet gateway (could be a UNO with w5100 shield, an esp8266 or mysgw compiled on raspberry)

[romeo01]

nrf24 connected to a arduino nano and plugged to the raspberry over the usb/serial cable is not considered as a serial device ?

What is this option ?

--my-gateway=serial

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:

That's exactly what I need, but how to do ??

./configure --my-gateway=serial --my-serial-port=/dev/ttyUSB0 --my-serial-baudrate=115200

Serial port /dev/ttyUSB0 is ok, because I use this with domoticz and it'running good.

My initial question is how to use my old gatway (arduino + nrf24) with the gateway compiled on the raspberry over the usb/serial cable ?
I can not use GPIO port.

[gohan]

The serial gateway on the raspberry does what your nano is doing and you can't have gateways talking to each other. Maybe you could look at mycontroller and see if can manage nodes the way you want.

[dirkc]

When talking about this Raspberry Pi Gateway, I suppose, that its just connecting the NFR24L01+ to the Raspberry Pi GPIO and run

./bin/mysgw -d

right? On my Pi it does not work this way, maybe the NFR24L01+ is not ok. Instead I am running an external esp-wifi-gateway, but a direct gateway seems the better solution to me.
So did I get it right, that I can use a NFR24L01+ connected to the Raspberry PI GPIO without any external gateway? If so, what are the parameters for building the mysgw daemon? I tried this one:

./configure --spi-driver=SPIDEV --spi-spidev-device=/dev/spidev0.0

update: as in https://www.mysensors.org/view/180#wiring
22 – CE
24 – CSN/CS
23 – SCK
19 – MOSI
21 – MISO

SPI is activated:

$ls /dev/spidev*
/dev/spidev0.0  /dev/spidev0.1

And this is the result, when building it with the settings mentioned above. (Raspberry Pi 3, jessie 4.9.13-v7+)

$ sudo ./bin/mysgw -d

And can someone show how to bind this gateway into FHEM? As said, today I am running an esp-wifi-gateay.

Thanks in advance for any support...

[romeo01]

@gohan
With the serial Gateway on the raspberry; how is connected the nfr24 ??
If usb/serial port is no possible, which serial port to use ?

[keldandorin]

@gohan Been trying to find my old post to tell you all how it got with my rpi and nodes that did not register. I bougt some voltage regulators LM350. used the 5v output insted of 3.3 V but still no luck to get node to register. when messauring volatage when GW send awnser it drops way below 3.3v. I think voltage output from rpi just is to bad. So I bought a nodemcu for GW instead and it works like a sharm

[marceloaqno]

@romeo01 You have to connect the nrf24 to the GPIO if you want to use it with the RPi, the information on the wiki was wrong, sorry about that.

[gohan]

@marceloaqno he said he can't connect nrf24 chip on the rpi, so that's why he is struggling

[marceloaqno]

@dirkc Try to connect your module to the SPI0 (https://www.mysensors.org/view/180#wiring).
You only need to enable the SPIDEV if you want to use the SPI1.

[gohan]

@dirkc I don't know where you got those pin numbers but they don't look like the ones on the guide. In addition you don't have to use spi driver. The PA version of nrf24 are quite a pain to get them working, so I suggest you first test with regular modules and then upgrade to PA

[dirkc]

@gohan, @marceloaqno : sorry, I corrected the "typo", the NRF was already connected as shown in https://www.mysensors.org/view/180#wiring. I double checked that again.
What is the correct setup for ./configure ?

[romeo01]

@marceloaqno

Thanks marceloagno, the answer is clear.

Keep up the great work !

[marceloaqno]

@dirkc The default settings for ./configure is to use the nrf24 module connected in the same way as shown in the guide and as an ethernet gateway.

[lshield]

I'm having issues with the LED setup as shown on the page. The LEDs are just constantly on even though everything looks like it's setup just like the picture. I'm new at this so I could be doing something stupid.

[dirkc]

@marceloaqno ok, thanks, I will change the radio.

[marceloaqno]

Support for RFM69 was added to the development branch (finally!).

[jirm]

@marceloaqno

I´m really happy ear that !

RFM69 is one of best RF transceivers in these days for IoT.
So good news I believe for Mysensors community.

You know if are any hope that RFM69 will be added too to OPI boards support mysgw development ?

Congratulations for that great work !

[marceloaqno]

@jirm Support for RFM69 also applies to the OrangePi

[jirm]

@marceloaqno

Awesome !!!
Thank you so much.

Best regards

[ftw64]

When I configure "MY_RFM69_MAX_POWER_LEVEL_DBM" in MyConfig.h, compiling fails.
Perhaps you should change the code in ./drivers/RFM69/new/RFM69_new.h from:

#define RFM69_MAX_POWER_LEVEL_DBM MY_RFM69_MAX_POWER_LEVEL_DBM //!< MY_RFM69_MAX_POWER_LEVEL_DBM

to:

#define RFM69_MAX_POWER_LEVEL_DBM ((rfm69_powerlevel_t)MY_RFM69_MAX_POWER_LEVEL_DBM) //!< MY_RFM69_MAX_POWER_LEVEL_DBM

[ftw64]

I cannot get the RFM69(HW) working. When I start myswg in debug mode (-d), I see:

mysgw: Starting gateway...

Is there any 'check' I can do to perform basic RFM69HW testing on my RPI?

[gohan]

Was it working before on a normal Arduino gateway? How did you wire everything up?

[ftw64]

I'm pretty sure I wired up the RFM69 correctly.
However, I'm debugging. It seems we are stuck in "core/MyGatewayTransport.cpp":

inline void gatewayTransportProcess(void)
{

  if (gatewayTransportAvailable()) {
    // NEVER REACHED

I never seem to get pass gatewayTransportAvailable. I will continue debugging.
Disclaimer: I'm relatively new to MySensors and not really 'up to speed' with the source code :-).

[ftw64]

@ftw64 Ok, this has to do with connecting an Ethernet client. When a client connects, this code works...
Any idea where to start debugging for incoming RFM69 messages?

[gohan]

Download myscontroller and connect it to the gateway, you can now see all messages from ethernet controller

[ftw64]

@gohan said in Building a Raspberry Pi Gateway:

myscontroller

I just did. When I also have a Domoticz controller connected to the gateway:

However, I found out that the DI00 (=IRQ) on the RFM69 never gives a rising edge...
I'm suspecting that the RFM69 is not being initialised properly... I added some debugging in the RFM69 code to see what registers are being written and read:

Can't get the RFM69HW to work on RPI. I tried the following:

1. I installed on an old RPI1 (clean Rasbian install). Same results as on my Domoticz RPI-3.
2. Setup the original RPI3 as a node, using the 2.2.0-beta code. I verified that in this case the RFM69HW actually transmits (I can hear it burst on 868.000 MHz). However, it is unable to connect to an existing Arduino 2.1.1 gateway.
3. I built an Arduino 2.2.0-beta serial gateway. Even then, the RPI as a node fails to connect to the 2.2.0-beta serial gateway.
4. I built an Arduino 2.2.0-beta node. This node is able to connect to the above gateway.

There seems to be something different in the radio network between the RFM69HW on the RPI and the RFM69HW on the Arduino. But I'm unable to find out what the difference is :-(.

The RPI RFM69HW will not communicate with the Arduino RFM69HW. When the RPI is a gateway, the RFM69HW will not physically interrupt when another node is trying to connect. When the RPI is a node, the RFM69HW on the ARduino does not interrupt either.

Did anyone get the RFM69HW working on the RPI? I'd really like to get this beautiful piece of code working!

[gohan]

I have to ask a stupid question : did you use a logic converter between rpi and rfm69 radio?

[ftw64]

@gohan There are no stupid questions, right :-)? But perhaps a stupid answer: no, I did not use any logic convertors. The RFM69 is 3.3V and as far as I know, so are the GPIO pins on the RPI. But I might be mistaken, of course... Should I use logic convertors?

At the moment I have no idea where it fails. Perhaps I need to give it a rest for a couple of days to think it over...

I followed the steps as given on the web site (git branch development). Connected the RFM radio (7 wires: Vcc, GND, MOSI, MISO, SCK, NSS, DI00). Only modified MyConfig.h with regard to the NETWORKID (100 --> 101; my 'production' MySensors runs at 100) and enabling "MY_DEBUG_VERBOSE_RFM69". I configured with:

% ./configure --my-debug=enable --my-config-file=/usr/local/etc/mysensors.dat --my-gateway=ethernet --my-transport=rfm69 --my-rfm69-frequency=868 --my-is-rfm69hw
% make -j 4
% sudo bin/mysgw -d

[mfalkvidd]

The gpio pins on raspberry pi are 3.3V. https://raspberrypi.stackexchange.com/questions/3209/what-are-the-min-max-voltage-current-values-the-gpio-pins-can-handle

[mfalkvidd]

@ftw64 that configure command looks like an ethernet gateway. Could you post the configure command for your "RPI as a node" as well?

[marceloaqno]

I forgot to mention in the guide:
To communicate with the RPi using the RFM69 radio, all of your nodes need to use the new RFM69 driver available in the development branch.
To make the change, add the following line to the node sketch:

#define MY_RFM69_NEW_DRIVER

[gohan]

@marceloaqno you forgot just a little little insignificant detail

[marceloaqno]

@gohan @ftw64 sorry for all the trouble

[gohan]

It's OK, don't worry. We need to update the guide with the new instructions

[marceloaqno]

@gohan Done!

[ftw64]

@marceloaqno Thanks! That indeed does the trick! And no worries, it is my own decision to play with beta(!) code (and it was a fun weekend troubleshooting it - I learned a lot about the structure of the MySensors code)!

Only 'bad' thing is that 2.2.0 is not compatible with my existing nodes :-).

I appreciate all the work that has been put into MySensors.

[Fat Fly]

This is really stupid. RFM69 radio need powered separately ?

[gohan]

They shouldn't, but it's always a matter trying

[Oliver Acevedo]

This post is deleted!

[Richard van der Plas]

How will this work with HASS running on the same pi ?

[gohan]

It's the same as it was running on separate hw, you will only set ip address of the gateway in hass

[Richard van der Plas]

so i can attach the NRF24L01+ to the pi running HA, make it a Ethernet Gateway and point to his own ip adress ?, will this be a long job with converting from a USB connected GW (Arduino with local sensors ? )

[gohan]

That's pretty much it. I don't know what is your current setup and what sensors you have, but is should not be a long job. Anyway you can install the ethernet gateway and when you are done you take care of the sensors

[Richard van der Plas]

excellent, will the cpu utilisation be much higher that with a usb connected gw ?

[gohan]

No, it uses very few cpu

@Richard van der Plas: I strongly recommend to use MQTT instead of Ethernet gateway, as it is a standard way for 2 processes to communicate, and platform-agnostic.
HASS comes with an embed MQTT broker taht works out of the box.
Plus:

• you can easily mock either your sensors network or your controller
• it does support secure communication
• you can add other clients to observe the event, e.g. to log what is coming from/what is sent to the gateway

[gohan]

I suggested ethernet because it's easier to setup and configure, mqtt is the next step.

Hi
I also have problem to get the NRF24L01+ chip to work with the RPi3.

I find that the masterbranch don't recognize the board as RPi3 and sets SoC and Type as unknown.
But if i take development branch it´s detecting RPi3 and seems to work correct.

This is result from development Branch configure:
[SECTION] Detecting target machine.
[OK] machine detected: SoC=BCM2837, Type=rpi3, CPU=armv7l.
[SECTION] Detecting SPI driver.
[OK] SPI driver detected:BCM.

[OK] init system detected: systemd.
[SECTION] Saving configuration.

This is result from Master Branch configure:

This is the result from cat /proc/cpuinfo:

[gohan]

That's odd, I have the 2.1.1 compiled on mine rpi 3

[marceloaqno]

@pettib @gohan There have been some changes in /proc/cpuinfo in newer versions of kernels which leads to a wrong detection.
The problem was fix in #827 and will be available in the master branch in the next mysensor release.

[gohan]

I'm using dietpi and I compiled it like 2 weeks ago..

[Fat Fly]

@Richard-van-der-Plas what is this: HASS ?

[Richard van der Plas]

Ok, i am standig on a crossroad it seems, i have to build a new gateway but i am also interested in the MQTT option, this is between mysensors & HomeASSistant i presume? i have some ESP's lying around unused, but i have 0 knowledge of mqtt (i dont think my hass has it running by default)

[gohan]

Just go with ethernet first that is easier, get used to it then take your time to learn MQTT. Of course MQTT is more advanced has authentication and encryption but it adds complexity to initial setup.

[Richard van der Plas]

Damn, just connected as in manual, but gives an error : mysgw: !TSM:INIT:TSP FAIL
Double checked the GPIO pins (except 15 cannot find that one) but seems ok

[Richard van der Plas]

NM, used GPIO numbers instead of Pin numbers RTFM

[A Former User]

I always have a mysgw: accept: Bad file descriptor error when I launch a new ./bin/mysgw -d Exact problem is the following:

mysgw: bind: Address already in use
mysgw: Failed to bind!

And I always need to kill the process first. Is this normal ? (I'm in LAN GW)

Thanks!

[gohan]

If you already installed mysgw as service to start at boot, it is normal that you can not run another process in debug mode and it conflicts

[A Former User]

@gohan said in Building a Raspberry Pi Gateway:

lready installed mysgw as service to start at boot, it is normal that you can not run another process in debug mode and it conflicts

Oh, Ok. Thanks.
Another thing is that when i close PuTTY, the gateway doesn't retrieve anymore the data...

[gohan]

You need to install it as service so it always runs in background

[A Former User]

Is it this process :

1421 ?        Rs    40:25 /usr/local/bin/mysgw

Seems it runs for 40 minutes, but no the gateway sees no data...

[gohan]

what gateway did you compile? What option in ./configure did you use?

[A Former User]

First of all : thanks for helping !

I compiled an Ethernet gateway
The options are the following:

./configure --my-gateway=ethernet --my-port=5003 --my-rf24-irq-pin=15 --my-transport=nrf24

The only way I make the GW working is through the debug mode (by switching off the service process)

[A Former User]

Hello, it seems I found the problem: Complete newbie thing:
sudo ./bin/mysgw -h worked, but /usr/local/bin/mysgw didn't
I just gave the right to the folder, and now it's working.
Thanks for taking time to help beginners !

[sillicius]

@Richard van der Plas : i was have the same error with my raspberry zero. I have succed with the devellopement branch version...

[gdekeijzer]

Trying to setup a Rpi1, as i got one lying around here.

All work untill i want to 'make'

Has this to do with a limitation of Rpi being v1?

[marceloaqno]

@gdekeijzer There was a recent update on the random number generator for the RPi port, but unfortunately not all linux versions support the new method. @d00616 is working on a solution to this problem #856. Please use the master branch for the time being.

[gdekeijzer]

Ah great. Thanx for the response. I'll go try that for now.

[gdekeijzer]

Installed master branche. That did the job. Thanx.

[Luc3as]

@Luc3as Okay, Again I found answer while after asking, I used dev branch of mysensors and it is working like a charm.

[zavracky]

I am a novice, trying to get the raspberry pi gateway to work. I did get it to work on one pi, but while installing it on the second, it produces the following error:

In file included from examples_linux/mysgw.cpp:74:0:
./MySensors.h:254:2: error: #error No support for nRF24 radio on this platform
#error No support for nRF24 radio on this platform

from examples_linux/mysgw.cpp:74:
./drivers/RF24/RF24.h:52:17: fatal error: SPI.h: No such file or directory
#include <SPI.h>

I can see that the SPI.h library is among the files downloaded.

Any ideas?

Paul

[gohan]

what raspberry version is that? What library version did you download?

[Luc3as]

do you have SPI enabled through raspi-config ?

[zavracky]

@gohan Thanks for the response. I downloaded the MySensors Library 2.1.1. Sorting through it I can see that SPI.h is included.

I installed a complete system in FL (I'm retired and a snowbird). Included are a Bunch of Arduino sensors, a Foscam Camera and Wemo switches. So I used a lot of material from MySensors to get the Arduino sensors up and running (great stuff: thanks to all those folks who created it). I then created a Raspberry Wireless (RF24) Gateway and installed Mosquitto to communicate with HomeAssistant. Took a while to configure HA, and I'm still learning.

I do not recall having a problem with the SPI library when assembling all this stuff. Upon return to Boston, I have made a number of improvements talking to the Raspberry in FL through TeamViewer (a great app). However, along the way, I corrupted the system in FL. It now limps. So, I started recreating the stuff in FL on a new SD card, encountering the SPI problem.

Since sending out my request for help, I found a backup version of my FL system on an SD card. Looking at it, the system seems to be whole and boots with no issues. mysgw works fine on it. So, I've added all my new stuff to this SD card and have tested it to make sure its working. Things are looking good and so, my immediate problem is solved (circumvented).

I still want to know what I am doing wrong with the gateway. I've learned a little bit of Python along the way. There, one installs a library. I know effectively nothing about C++. So, I've done nothing to install the library, only followed the instructions on the MySensors Raspberry Pi Gateway page.

BTW, this stuff is great.

Paul

[zavracky]

@Luc3as Thanks for your response. No, in fact it was not enabled. Please read my reply to gohan. As you see, I've cheated my way out of this problem. In the process, I've lost track of the SD card on which I encountered this problem. Nonetheless, I will circle back to test your suggestion.

[gohan]

Try to enable the SPI first. Then you could also try different linux distributions and see which one you like better ( I personally like dietpi more than the others ). You may also want to try to use Mysensors library from development branch that is now 2.2.0.
I now have a dietpi + mysensors 2.2.0 + nrf24 and all running fine

[subutux]

@marceloaqno said in Building a Raspberry Pi Gateway:

@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.

But why do we need to convert down from 5v to 3.3v? The pi does supply 3.3 on some pins.. Is this because the PA/LNA uses more mA?

[gohan]

yes, the 3.3v can't supply enough current. I am using some small adapters that have the AMS1117 and some capacitors that allow for a quick swap of radio modules when you need test them

[subutux]

@gohan said in Building a Raspberry Pi Gateway:

yes, the 3.3v can't supply enough current. I am using some small adapters that have the AMS1117 and some capacitors that allow for a quick swap of radio modules when you need test them

Ok. Maybe this should be mentioned in the documentation page.

[mfalkvidd]

@subutux could you explain where you would expect to find that note?

[mfalkvidd]

(obviously not here)

[gohan]

@subutux it is mentioned as stated above that you need it, it is just skipping all the info that are in datasheets and are not stricly necessary to make the gateway

[subutux]

@gohan said in Building a Raspberry Pi Gateway:

@subutux it is mentioned as stated above that you need it, it is just skipping all the info that are in datasheets and are not stricly necessary to make the gateway

Well, I for one would like to know why we need to step-down from 5v to 3.3v. Just a simple statement that the LNA version requires more power that only the 5v can deliver on the pi.
@mfalkvidd Yeah I would mention it there. It mentions to use a regulator but not why.. I've read that line & was like, why? That's when I've started a search in the forums here.

[mfalkvidd]

@subutux I've updated the text. Do you think it is ok?
