💬 Building a Raspberry Pi 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.

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

Roberto Mo Ca

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?

macvictor

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?

Do I need to configure all the info on the same command, or can I send the command "./configure --" many times for different configs?
Do I need to configure it as a MQTT gateway?
Where did the 127.0.0.1 IP come from?
Does MQTT use internet connection?
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

marceloaqno

@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.

Madhias

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!

macvictor

@marceloaqno Thank's for you help. I have other question.. general I try configure my gateway to work with security & signing, but they doesn't work. Where is problem? On the bottom i send point what it do it:

Where is problem?

marceloaqno

@macvictor Did you also enable encryption on your node? (#define MY_RF24_ENABLE_ENCRYPTION)

macvictor

@marceloaqno Thanks for help This was my problem

gohan

how do I set user and password to access the mqtt broker? I tried do add --my-mqtt-password=PASS --my-mqtt-user=USER other parameters but they get ignored

macvictor

@gohan edit configure file and add this code:

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

after this code:

--my-signing-request-gw-signatures-from-all*)
        signing_request_signatures=true
        CPPFLAGS="-DMY_SIGNING_GW_REQUEST_SIGNATURES_FROM_ALL $CPPFLAGS"
        ;;

this is about 408 number line and use flag --my-mqtt-password and --my-mqtt-client-id when you run configure, thats all.

blacey

@macvictor It would be great if you would submit this as a GitHub Pull Request. If you aren't comfortable with that, then I would encourage you to at least open a MySensors issue to add these RPI configuration options.

Teknor

When using RPI as a GW for MySensors, the CPU load increases from 18% to around 80 %. I am using a RPI II model B. I'd love the have the GW running on the Raspberry, and avoid a USB connected Arduino.

Does somebody else experience the same?

macvictor

@Teknor I use RPI III as GW and all node connect with gw used nRF24L01. My CPU now usage 5-10%, but I installed "Home Assistance" + homebridge + some plugins.

Teknor

@macvictor Thanks. My RPI 2 is running Domoticz, RFXcom GW and 2x 3MP cameras with motion detection using Motioneye. Might be something wrong with my MySensors GW setup...

carlyler

@Teknor I tend to agree something is wrong, but I think it really on depends how many nodes and how often you're sending data.

@macvictor
That worked, thanks. But to configure channel, power, AES key, and so on, do you think it is better to use command line like you posted above or customize myconfig.h?

marceloaqno

@gohan You can also set mqtt username and password in examples_linux/mysgw.cpp

gohan

@marceloaqno
I'm trying to understand where is the best place to avoid file gets overwritten in case of upgrades

marceloaqno

@gohan There is a open github pull request very similar to what @macvictor proposed, but for now I recommend using the examples_linux/mysgw.cpp file.

gohan

@marceloaqno
Ok I can you that file, but where is the best place to set Power Level and channel ?

marceloaqno

@gohan There isn't exactly the best place to set things, it really depends on your preferences.

gohan

I just copied the myconfig file from the arduino and set the rest from the command line and from debug it looks like it's working, the problem is now to get domoticz talk to the mqtt.

gohan

After updating domoticz to beta version I finally have the MQTT working with controller and I can see the sensor node seding in data: my question now is how to I debug the gateway if it is running as a service on the RPI without messing things up?

marlin

@marceloaqno I am trying to get a Pi 3 working with MySensors 2.1.1 and nrf24l01 and using your updated wire guide, but all I get as output is the following:
mysgw: Starting gateway...
mysgw: Protocol version - 2.1.1
mysgw: MCO:BGN:INIT GW,CP=RNNG--Q,VER=2.1.1
mysgw: TSF:LRT:OK
mysgw: TSM:INIT
mysgw: TSF:WUR:MS=0
mysgw: !TSM:INIT:TSP FAIL
mysgw: TSM:FAIL:CNT=1
mysgw: TSM:FAIL:PDT
[The output repeats itself, increasing the CNT every time, while at the same time one of the cores on the Pi 3 is running at full CPU utilization.]

By reading earlier comments I assume this is a wiring problem. One possible cause is inconsistency between
0_1488723559852_upload-e3165792-1f42-4663-8e68-efd96bd275f8

and

0_1488723638471_upload-d7048ef8-8a33-4214-9935-0356cf9291c2

where the first picture indicates that pin 24 and pin 26 should be used, while the second indicates pins 22 and 24 should be used. However, I have tried both options but I still get the same output (I used different nrf24's for the different setups, in case the nrf24 got burned from the first setup).

I have VCC from nrf24 connected to pin 17 on the Pi 3 and GND connect to pin 25.

Any suggestions on what to try next?
[The Pi 3 is running Raspbian with Pixel. For information, I already have a running Arduino with MySensors MQTT GW and a simple node with MySensors and DHT22. From this I know that by nrf24 chips works when being fed with 3.3V.]

gohan

I have connected my nrf24 like the secon table you posted and it is working but I am using an "adapter" for nrf24 with a socket and has voltage regulator + capacitors, so if you don't have any cap on the radio module, I'd suggest you put one on (try from a 4.7 uF up to 47 and see if anything changes)

marlin

@gohan Thanks! You were correct. I also had one of those "adapters" lying around which I did not need for my Arduino nodes with MySensors, though it came into use for the Rp3.

After updating domoticz to beta version I finally have the MQTT working with controller and I can see the sensor node seding in data: my question now is how to I debug the gateway if it is running as a service on the RPI without messing things up?

I have my gateway on a headless pi 3, no monitor, GUI or keyboard. (I don't care for the nest of wires connection to the pi.) I also use MQTT which is very reliable.

An easy way to see the full MQTT traffic is to not start (or kill if it starts on boot) the MQTT server in the background, and start it in the console you can monitor. This won't impact Domotics one bit. In my case I do this by invoking "mosquitto -d" in the terminal

A simple way to monitor MQTT once its up and running is to look at the Domotics Log on the Setup menu.

Another way to watch it is to, in a terminal window such as running ssh from your computer, use MQTT "sub" in your terminal to see the MQTT traffic both ways to and from Domotics. If this isn't familiar, you need to learn it, (read the MQTT docs) and it's quite simple. Example might be "ssh pi@rpi.local" or "ssh <IP address>" from a computer on the local network, assuming the user is named pi and the pi is named "rpi"

Your MQTT topic must match what is in the sensor node sketch, the gateway sketch, and the domotics MQTT config. In my case I use "mosquitto_sub -d -v -t domoticz" and everything starts showing in real time in the terminal window.

MQTT is a bit more fiddly to set up but it's nice that different environments can push sensor data into the same MQTT server, in my case MySensors and ESP Easy.

Be careful because the wiring page shows two pinout diagrams, one for the Pi 1, another for the Pi 2&3, but which is which is not inside the graphic itself. Please don't ask how I know.

Tim

gohan

@Grubstake
I am using mqtt fx from pc and subscribing to topic # so I get the full traffic of what is going on, but I haven't had time lately to compare if you get same log details as the myscontroller connected to ethernet gateway or starting the gateway on rpi with debug flag

keldandorin

@marlin Got the same issue, Did you solve yours and if so how?

marlin

@keldandorin Yes. See the response by @gohan. I used a "adapter" with a voltage regulator on it etc. Though, at the moment I don't recall the model number.

gohan

@keldandorin just add a capacitor between vcc and gnd on the radio module as I suggested above.

ccy

I am trying to connect NRF24L01+ and Raspberry Pi 2 (Model B+). I am confuse about pin 22/24 too. In the diagram it shows "SPI0 CS0" and "SPI0 CS1" but these two pins aren't exist in NRF24L01+. How should I connect the pin? I connect Pi2 pin 24 to CS and Pi2 pin 26 to CE (Not sure it is correct)? Here is the message from mysgw:

@ccy Look at the chart below "NRF24L01+ Radio". That shows the PIN numbers on the Pi and the pin labels on the radio to interconnect. Pay no attention to the labels on the RPi generic pinout diagram except the PIN numbers. The RPi SPIO labels are not what you are looking for. And be sure to use the chart for the correct RPi model.

gohan

Exactly, I was about to write pretty much the same

Grubstake

@gohan I beat you to it!

@Grubstake: Thanks. I have tried to follow "NRF24L01+ Radio" pin out connection. I have double / triple check my wiring is correct. But I still get the same fail message in mysgw debug mode:

I can run mysgw. But what can I use it for? I want to make it control my light with 2.4G RF. But I don't know what to do next. Please advice Thank you.

gohan

@ccy
You need to provide some more details about your hw and general setup, what have you done so far, log messages, etc.

ccy

@gohan Sorry for my typo mistake. I can now run mysgw. But what can I use it for? I am trying to control my light with 2.4G RF.

gohan

Do you mean your light has already 2.4G RF or do you need to make a relay node with NRF24 that can switch on and of that light? But this is going a little OT in this thread.

ccy

@gohan Yes. I want to do that. I am sure my LED controller is 2.4G RF. But I can't detect any signal yet from my nrf24l01+ on raspberry pi. I am not sure what's wrong. Still trying now...

gohan

@ccy
Being 2.4G RF doesn't mean it is NRF24L01 compatible also without knowing what channel is using will make it even more difficult. So, unless you want to make a Mysensors LED Controller, I think you are out of luck if you want to directly control your existing one with a RPI and the mysensors gateway. Either way this is OT.

ccy

@gohan Is there a way to know the channel by doing some sort of scan? If the channel is known, what are the setting to fix the channel for mysgw?

Velo17

Hello everyone!

I'm using a Rasp2 (with the 40 pins GPIO header)

Has anyone experience with using the NRF module on different pins than default? I'm asking because I wonder if I can connect a GPIO-connected touch TFT (which would use the 2 CE lines for the touch and display interfaces) together with the NRF - by hooking the MISO/MOSI/SCLK to the default pins (and thus sharing them between the TFT and NRF) and defining free pins for the CE and CS lines in the ./configure script when compiling the gateway code...?!

Or maybe using the SPI1 by first enabling it as laid out in this blog post - but how to proceed from there? (How to tell the gateway code to use SPI1?)

marceloaqno

@Velo17

./configure --spi-driver=SPIDEV --spi-spidev-device=/dev/spidev1.0

(replace the /dev/spidev1.0 with the one you enabled in /boot/config.txt)

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.
Br
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

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

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

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

@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

@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 ?

@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.

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.
