💬 Building a Raspberry Pi Gateway

[Reza]

@marceloaqno can you build a rs485 gateway on raspberry pi ?

[eyesoft]

@Mihai yes you are right

[Shantanu Mhapankar]

This data that I get when I run ./mysgw --d , where is it stored and how can I get it to push it on cloud? Please help.

[Tag]

@Shantanu-Mhapankar

Data is not stored... to store the data and do something usefull with it (or not) you need a controller. I use mycontroller, and from this software you can "push" data to an external server.
I use my controller, but i am sure that other controller software also has this feature.

[Shantanu Mhapankar]

@Tag , The controller must be using something to get the data right? How can we do it directly without using the controller?

[pete1450]

@hek It looks like development is the default branch in the repository. I was following the build instructions and couldn't figure out why I kept getting "connection refused". Just typing up a troubleshooting post when I saw my log said 2.2.0-beta. Sure enough when I grabbed master(2.1.0) instead it ran fine. Should probably add a checkout in the instructions.

[mfalkvidd]

@pete1450 could you clarify which instructions should be updated?

The instructions at https://www.mysensors.org/about/arduino recommend using the Arduino IDE Board manager, which will get the latest stable version.

Edit: Now I see. The link in the first post in this thread. It doesn't mention the master branch because up until Dec 25th the development branch was required. But now that 2.1 has been released the instructions should indeed use the stable version. I've updated the instructions. Thanks for noticing!

@Shantanu-Mhapankar

This is also new for me since i do not send data into any cloud... but i can imagine that you can use MQTT. (see https://www.mysensors.org/build/mqtt_gateway for more details) is important that the receiving side supports MQTT. in this case google is your friend

if you do a ./configure --help you will find you can build the mysensors gateway with MQTT support

./configure --help 
...
    --my-gateway=[ethernet|serial|mqtt]
                                Gateway type, set to none to disable gateway feature. [ethernet]
    --my-node-id=<ID>           Disable gateway feature and run as a node with given id.
    --my-controller-url-address=<URL>
                                Controller or MQTT broker url.
    --my-controller-ip-address=<IP>
                                Controller or MQTT broker ip.
    --my-port=<PORT>            The port to keep open on gateway mode.
                                If gateway is set to mqtt, it sets the broker port.

ran sudo ./bin/mysgw -d
I keep getting mysgw: accept: Bad File Descriptor.
Any possible cause ?

[marceltrapman]

I am trying to get the raspi ethernet gateway running but on both my pi 3 (also running openHAB) and the pi B (pretty basic install).

Unfortunately I get the same error on both.

Any ideas what could be going on here?

I am running the latest gateway and the latest raspbian.

@marceltrapman

I am using a Rasp Pi 3 as well.
I can't even proceed further in the tutorial cause of this error cause nothing works after it.

[marceloaqno]

@marceltrapman @LaMB95
Could you post the complete ./configure command used to configure the gateway?

[marceltrapman]

@marceloaqno Sure, forgot it

sudo ./configure \
    --my-gateway=ethernet \
    --my-controller-ip-address=192.168.1.xx \
    --my-port=5003 \
    --my-transport=nrf24

[marceloaqno]

@marceltrapman Are you sure it's not a problem with your controller?
Have you tried connecting to your controller using telnet?

telnet 192.168.1.x 5003

[LaMB95]

@marceloaqno !

Is this what you meant?

[marceltrapman]

@marceloaqno not sure no.

So, I downloaded telnet on the same raspi that I want to use as the gateway and the issue seems to be that port 5003 is not available.

Funny but how do I solve this.
It can't be an issue with the firewall because it allows all traffic on the internal network.

[marceltrapman]

@marceloaqno and the same from the controller to the gateway gives the same error on that port

[marceloaqno]

@Reza Yes, you can use rs485 in the RPi.

./configure --my-transport=rs485 --my-rs485-serial-port=<YOUR_SERIAL_PORT>

For more options, run:

./configure -h

[marceloaqno]

@LaMB95 No, I meant the options you used when you ran ./configure

[marceloaqno]

@tiana
"The Broadcom SoC has three independant SPI interfaces, however only one of these is brought out to the GPIO connector, and that one SPI interface has 2 Chip enable lines."
More info here: https://www.raspberrypi.org/forums/viewtopic.php?f=44&t=22608

[marceltrapman]

@marceloaqno from the docs I assume it is the gateway that has to open up port 5003 but I guess it does not because it can't connect to the ethernet (for some reason) or am I wrong?

[Reza]

@marceloaqno
i means that without arduino and usb port, similar to raspberry gateway ( raspberry +nrf24)
i means connect rs485 module to GPIO raspberry pi with domoticz

[LaMB95]

@marceloaqno

I m sorry I m new to using a raspberry pi and its for a project.
But if this is not what you asked for could you be a little more specific :$

[ericvdb]

use sudo

[marceltrapman]

Oh and one other thing, when I set the gateway up for MQTT it works.

[marceloaqno]

@marceltrapman

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.

[marceloaqno]

@Reza You could connect the rs485 to the RPi UART and use the option --my-rs485-serial-port=/dev/ttyAMA0, but you need to turning off the UART functioning as a serial console.

Or, to make things easier:
rs485 <==> TTL/USB <==> RPi

[Reza]

@marceloaqno
i am beginner and i can not turning off the UART functioning. . . also on some board usb port after power off/on lost and i should disconnect/connect cable... i test your steps serial gateway with raspberry and GPIO with virtual usb serial . and i see this problem solve and after power off/on gateway is connect .
i suggest that you add this commands to page of rs485 gateway step by step and update this .
(https://www.mysensors.org/build/rs485)

I thank you for hard working and trying

[b0rmann]

@Reza

if you want use rpi /dev/ttyAMA0 for rs485 gateway -

1. remove string "console=serial0,115200" from /boot/cmdline.txt
2. add strings "enable_uart=1" and "dtoverlay=pi3-disable-bt" to /boot/config.txt (only on rpi3)
3. reboot raspi

[marceltrapman]

@marceloaqno nice, working now

Thank you...

[Reza]

@b0rmann
thank you friend , but i am sorry i am very beginner in raspberry pi . because i use vera before and with raspberry and orange pi i use recently. so i need a full steps for a rs485 gateway(wiring and commands . . .) i dont know what is ttyAMA0 ! i use a serial gateway with usb port with raspberrypi 3 but i have some problem , but with a raspberrypi gateway and use a virtual serial port (ttyUSB020) all of my problem resolve. but i have problem with wireless. so i want have a wiring network. i want a full steps for setup a rs485 module with raspberrypi 3(wiring and steps for install...) thank you for help

[Anduril]

Do I read that correctly, does this gateway also gives a ethernet link to a serial-only controller? How do I have to configure ip and port? In the build section I see no option to set them.

[LaMB95]

@LaMB95 said:

@ericvdb

Okay what could be the problem? :3

[marceloaqno]

@Reza There are many guides on the web teaching how to connect and use rs485 with the RPi. I recommend you start with them and when you are sure it is working, you add MySensors to the equation.

ok thank you

[Tag]

@Anduril
you will get all the build options for the mysgw with the command

./configure -help

Here you can configure all options like serial and ethernet

[Anduril]

just cloned and read the --help, but still I don't know how to use.
To make it a litte less abstract: I have a ethernet gateway (ESP8266) running at 192.168.38.19 with port 5003 to connect to. I want to have this accessible by a serial-only controller on the raspberry.

I tried to do this config and make afterwards, but starting gave only FAILs...

./configure --my-gateway=ethernet --my-controller-ip-address=192.168.38.19 --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway

I think my config is wrong and it tries to connect to a nrf24 at the rpi. So what's the correct config for my case?

Thanks in advance.

[gohan]

@Anduril
Why are you using an esp8266 as a serial gateway? Wouldn't it be easier to use a normal UNO?

[Anduril]

I'm using a ESP8266 as ethernet gateway and want to have this connected as virtuall serial port to my raspberry pi so my controller can connect to that.

[lakshmc]

I using RPi2 and NRF24 for this. I followed the instructions, to clone the repo, and then added config
./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 --my-transport=nrf24

make

when i run with sudo ./bin/mysgw -d, it is failing to connect to MQTT. Can you please help?

@Anduril

Have you aver considered Using the GatewayESP8266MQTTClient? What controller are you trying to connect?

[Anduril]

I use pimatic which does not have a native compatibility to ethernet or mqtt. Thats why my question came up on how to configure it to do this...

Building a Raspberry Pi Gateway:

If you are running a controller on the Raspberry Pi that doesn't support communication with the gateway through ethernet, you can use a virtual serial port:
./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway

[mfalkvidd]

@Anduril you might be able to use nodered or socat to convert the tcp connection to a serial port.
https://linux.die.net/man/1/socat
https://nodered.org/

[Anduril]

that's what I tried in the past and am using now (socat), but it does not reconnect and has some other drawbacks. Reading of an officially supported way sounded interesting

[pete1450]

@lakshmc Make sure you don't have the daemon running already

If not, I'm getting the same problem on the 2.1.1 that was just released. 2.1.0 was working "fine"(besides my suspecting a bug that doesn't let any inclusion happen, hence I tried the new version). Time to go back to the serial gateway right into the vera.

[marceloaqno]

@pete1450 @lakshmc
Make sure you are not using an old version of mosquitto (or any other broker you're using):

$ mosquitto -h
mosquitto version 1.4.10 (build date 2016-09-20 11:02:07-0600)

It's working fine with the 2.1.1 release:

@pete1450 Could you send the debug log with the connection errors?

@marceloaqno After installing broker and gateway fresh, seems to be working. Thanks for your help.

@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?

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

[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]

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.

[gohan]

@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

and

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.
