💬 Building a Raspberry Pi Gateway

shfg

Thanks for this excellent port. I'm having an issue running it as an MQTT gateway on the RPi (Model A). It compiles without hassles, but cant make a successful MQTT connection. I get the following:

mysGateway: Starting gateway...
mysGateway: Protocol version - 2.0.1-beta
mysGateway: MCO:BGN:INIT GW,CP=RNNG---,VER=2.0.1-beta
mysGateway: TSF:LRT:OK
mysGateway: TSM:INIT
mysGateway: TSM:INIT:TSP OK
mysGateway: TSM:INIT:GW MODE
mysGateway: TSM:READY
mysGateway: MCO:REG:NOT NEEDED
mysGateway: MCO:BGN:STP
mysGateway: MCO:BGN:INIT OK,ID=0,PAR=0,DIS=0,REG=1
mysGateway: Attempting MQTT connection...
mysGateway: connected to 127.0.0.1
mysGateway: Attempting MQTT connection...
mysGateway: connected to 127.0.0.1
mysGateway: Attempting MQTT connection...
mysGateway: connected to 127.0.0.1

... those attempts recurring every 15 seconds or so, and in that time, no other activity is processed.
From the code, I would have expected 'MQTT connected' rather than 'connected to 127.0.0.1'?

I have mosquitto running on the pi in this case - which is working perfectly in other tests. Both serial and ethernet gateway modes compile and run perfectly, only the mqtt mode not working.
Has anyone else had a similar issue?

@marceloaqno what about gpio interrupts, is that supported?

I'm thinking to use a RPi as a pulse counter for water, electricity and gas with no radio, just ethernet or mqtt.
In combination with a I2C display, this could be a nice project

Hi,

I have a raspberry Pi 2 that I've installed MyController on. This works fine, I can access it via the browser. I have also wired up an NRF24L01+ module to the GPIO pins on the Raspberry Pi. And I have followed the steps under "install and build", which seem to have worked fine. I didn't make any changes to the conf file. However now Im stuck. How do I setup the Raspberry Pi with the NRF24L01+ as a gateway in the MyController Gateway setup page in Safari?

marceloaqno

@shfg There were some reports about this problem in the past, do you see any error messages in your mosquitto log?

@ericvdb yes, you can attach a function to handle an interruption like this:

uint8_t mode = FALLING;	// Valid options are: CHANGE, FALLING, RISING
uint8_t physPin = 16;	// Choose a pin that fits your needs

void irqHandler(void)
{
	// Process the interrupt
}

void setup() {
	attachInterrupt(physPin, irqHandler, mode);
}

Support for I2C was added in the latest version.

@Christian-Simonsen If you are using the default build options for the RPi gateway, in MyController (Resources -> Add gateway) choose Ethernet for the type and enter your RPi ip address in the Host name field.

Toyman

Is it compatible with pre-2.0 versions eg 1.5?

Thanks that did the trick

Hi,

Background: I have a raspberry Pi 2 that I've installed MyController on. This works fine, I can access it via the browser. I have also wired up an NRF24L01+ module to the GPIO pins on the Raspberry Pi. I have also set up the raspberry pi as a gateway in the MyController Gateway setup page in Safari. It found it and it seem to work.

However to my question. How do I know if the Raspberry Pi gateway with NRF24L01 work? How can I monitor what the Raspberry Pi gateway receive? Is there a similar way as the "Serial Monitor" that I use in the Arduino application, when accessing Arduino Uno via USB?

If there is I need to monitor this via OSX Terminal.

Today i tried to use the sketch Water Meter Pulse Sensor in mysGateway.cpp but i run into alot of errors, you have any idea?

mysGateway.cpp:

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

Toyman

I probably miss something, but why are trying to compile the arduino sketch on Raspberry Pi???

hek

@ericvdb

As @Toyman implies, we haven't ported the full Arduino environment here. This should mainly be used for running the Serial/Ethernet gateway directly on your RPi.

You cannot just run any MySensors example without risking to make heavy adaptations/implementation on your own.

marceloaqno

@ericvdb micros() hasn't been ported, use:

millis() /1000;

for sleep(), replace:

sleep(SEND_FREQUENCY);

with

sleep(SEND_FREQUENCY, false);

Also, if you want to print something don't use Serial.print() or Serial.println(), use printf() or debug().

Serial.print("l/min:");
Serial.println(flow);

should be:

debug("l/min: %f\n", flow);

as @hek said, the main focus now is to be used as a gateway, with time adding sensors will become less problematic.

ericvdb

@marceloaqno
I have it almost working. Regarding the interrupt, I have to pull-up to 3.3V the io pin through a resistor of 10k?
Right now the interrupt isn't firing

shfg

@marceloaqno thanks, turned on mosquitto logging and am getting this error on mosquitto:

1476724216: Invalid protocol "MQTT" in CONNECT from 127.0.0.1.
1476724216: Socket read error on client (null), disconnecting.

Tried an alternative mosquitto broker on another server too - same error.

@marceloaqno

I have it working only need to play with the debounce value

shfg

@marceloaqno I finally have the MQTT gateway working after upgrading mosquitto to the latest build... I had installed mosquitto with apt-get under Wheezy which apparently pulled an older version. In retrospect probably should have just upgraded to Jessie from the outset! Working perfectly now (still under wheezy though FWIW)... thanks!

@Christian-Simonsen start the gateway with debug enabled:

mysGateway -d

jerseyguy1996

@Christian-Simonsen If you don't have debug enabled you could also just use:

tail -f /dev/ttyUSB20

My port is named ttyUSB20. You should substitute whatever you have named your port.

Christian Simonsen

@jerseyguy1996

Thanks I'll test it. But it seems like I've jumped over a step or two. Or something isn't working. Nothing happened when I wrote "Make" in Terminal, so I jumped over this step. I guess that might be the problem.

Do I have to configure (./configure -help) or can I use the default values when I connect the NRF24L01 to the GPIO pins?

marceloaqno

@b0rmann what happened? Did you fixed the problem you described in your last message?

b0rmann

@marceloaqno

it's my problem. accidentally disconnected power from nrf24 on running gw

ericvdb

@marceloaqno I have it completely working now. A Raspberry Pi PulseCounter for water/gas/electricity consumption measurements with ethernet/mqtt. I can post my code here if you want.

Minor detail:

millis() / 1000;

should be

millis() * 1000;

to get micros()

marceloaqno

@ericvdb Congrats! oops, sorry about my mistake.

Seems I'm closing in to working solution. I didn't understand how to use the ./configure element before now. However I ended up with these configurations

Thanks for adding signing.

I want to use my rPi to generate random soft serials for my sensors.
Could all three "gen" commands output the line to put in SecurityPersonalizer.ino like it does when using the "set" commands?

marceloaqno

@Christian-Simonsen you need to be within the MySensors folders to execute commands configure and make.
I recommend you to test that everything is working before using the option --my-rf24-irq-pin=15

Like this:

cd MySensors
./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway --my-radio=nrf24
make
sudo ./examples_linux/mysGateway -d

marceloaqno

@NiklasO Done (#622). Thanks for the sugestion.

Christian Simonsen

@marceloaqno said:

cd MySensors
./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway --my

Thanks for letting me know, didn't know that not running it from the specific folder would have an impact.

I reconfigured it as you recommended. and restarted the gateway, with the result below.

Hi,

Is there anyone here that can give me some one-to-one support this evening to setup the Raspberry Pi + NRF24L01 as a gateway with MyController, and a Arduino Uno + NRF24L01 as Sensor node. I'm stuck after trying various things over the past week, so looks like I need some additional skills/knowledge to get the first setup working.

Maybe we can use Skype or some other medium. I will gladly pay a bit for this support if anyone is interested. I have some free time from 18:00 CET - 23:30 CET today...

nico

hi, the gateway works but how display sensors in domoticz?
Thank you very much

alexsh1

@nico you need a sensor to send data to GW and assuming you have GW added to Domoticz, Domoticz will add up corresponding values to "Devices"

nico

I have a gateway and 1 sensor ,obviously.
I have added serial GW but anyone sensor appear, i'm sure that the sensor works, and the gateway also (see with the command mysGateway -d).
Can you have any idea ? Thank you

alexsh1

@nico I would suggest you open up a different post in the Troubleshooting section regarding this matter
1 post GW and sensor logs
2. How do you know that the GW was added to Domoticz? Logs please?

jerseyguy1996

@Christian-Simonsen

You can pretty much test out using any of the arduino examples here:

https://github.com/mysensors/MySensors/tree/development/examples

Each one will present itself to the gateway when it starts up and you will see the presentation in the debug log. Make sure to run:

https://github.com/mysensors/MySensors/tree/development/examples/ClearEepromConfig

on the arduino first to make sure it starts with a fresh eeprom. After you select an Arduino sketch to test it with (seriously it doesn't matter which one you try) make sure to look at the sketch and add:

// Enable and select radio type attached
#define MY_RADIO_NRF24
#define MY_NODE_ID 4

For MY_NODE_ID you can select any number. Just make sure that each new sensor node that you create has a different node number so like start out at MY_NODE_ID 1 and when you make another sensor node you can #define MY_NODE_ID 2 and so on.

Next load it up to the Arduino, open the serial monitor, and see what happens. If you watch the serial monitor on the arduino you will see it present itself to the gateway and then you can confirm it in the debug log on the raspberry pi.

I think it is pretty normal to have the problems you are having. I uninstalled and reinstalled the gateway 3 times on the Raspberry Pi before I finally got it all figured out. Once you get it running it is a glorious thing.

Ok,

I've tested with the Voltmeter and the NRF24L01 module do get a steady 3.26 V. Both the gateway module and the Arduino sensor node...

Im now building a few extra sensor nodes, so I can test without the Raspberry pi. Hopefully I can atleast get them talking based on Arduinos first. Before testing the Raspberry Pi.

I haven't seen anyone doing anything similar so it might require some work. But almost anything is possible given enough work

jerseyguy1996

Has anyone else had an issue with getting a sensor node to reconnect after a lost connection? I can see it attempting to reconnect but even though it is back within range of the gateway it won't reestablish the connection. If I reset the node it re-establishes the connection without any problem. This is the cycle that it gets stuck in:

@Christian-Simonsen multimeter will not detect issues with the power feed (noise or unstable). It just says that you voltage under zero load is 3.3V.

carlyler

Appears things are changing, please update wiki:
Warning: --my-radio is deprecated, please use --my-transport

Patrik Söderström

@mfalkvidd Alright The thing is that I have my Raspberry Pi as a Gateway today near my server rack and would like to measure the temperatur. Maybe I just get a Nano to do the work for me. Just would have been great to use the Raspberry.

mfalkvidd

@Patrik-Söderström You can probably connect a temperature sensor to the gpio pins and have your controller read the sensor (without using MySensors)

marceloaqno

@carlyler Thanks for pointing that out.

marceloaqno

@jerseyguy1996 Are you using a decoupling capacitor?

jerseyguy1996

@marceloaqno Yes its 220 uF. It was all I had handy. I read somewhere that this may be a problem specific to the arduino nano. I may give it a try with the pro mini. Although I'm not sure what that may have to do with it.

Edit: I tried the same sketch on an arduino pro mini and it worked fine. When I simulated a loss of connection by walking out of range of the gateway it immediately reestablished the connection when I got back within range. The only difference is that the pro mini is running at 8 mhz whereas the nano runs at 16 mhz. Not sure how that affects things.

Velo17

Hello everyone. Is there a way to reduce the number of Heartbeat messages the gateway produces by itself? Using MYSController to analyze the data traffic, I see every 10 seconds a Heartbeat - would like to reduce this once everything is working as expected to maybe every 5 or 10 minutes...

hek

@Velo17

Just sleep longer. It sends one heartbeat every time the node wakes up.

dopeeye

@Christian-Simonsen

I have exactly the same error

mysGateway: !TSF:MSG:LEN,0!=7

Have you been able to resolve that problem yet? I have tried multiple radios with different capacitors and powersources grounded to the Raspberry Pi.

thanks

Christian Simonsen

@dopeeye

Sadly not. I ended up creating an serial gateway (arduino with NRF24L01 and a USB connector) and connected this to the Raspberry Pi, rather than connecting the NRF24L01 directly to the GPIO pins. This worked perfectly straight away.

dopeeye

@Christian-Simonsen

Too stubborn to give up, yet.
If i find a resolution I will let you know

Graham

I would like to try this, but my pins19-23 are already used by other hardware. Has anyone tried using the SPI1 Pins?

carlyler

@dopeeye I had this issue and unfortunately changed several things at once and got rid of it. However, one thing I noticed was I had different versions of mySensors in my library directory since I downloaded the examples package. Therefore the sensor was likely compiling on a different version than the Gateway. You might want to check that.

If you could post more of your logs (sensor and gateway) it might help.

@alesc looks like this commit in the development branch broke the code.

Do

git checkout master

before running configure should get the code to the latest stable release.

ben999

Hi Everyone !
Big thumb up for the amount of work supplied !!!
After being more or less successful with openHAB1 I had a go with openHAB2 today, via a online install....
But no success with the "mysGateway" install : should i go back to serial gateway with an arduino ?
Thanks a lot for your help

carlyler

@ben999 try again, because it works great. I assume by online install you mean apt-get; I too had trouble when trying this. However, I tried again following @TimO instructions here:
wiki, then everything came up nicely. I feel it is some permission issue that I have not tried to figure out yet.

marceloaqno

@ericvdb when running as a service, debug messages are masked and aren't shown in the system logs, but it would be a good idea to have a way to connect to gateway perhaps using telnet and watch the logs. I'll work on something.

ben999

@carlyler
Thanks a lot for your message, hope is back on my side
Actually I had a go with openHABian (i didn't make it clear in my previous message, sorry)
The install itself couldn't be easier : OS+openHAB installed in one go, just by formatting SD Card with a tiny img file. One hour later and voilà !
So that could be the source of my trouble?
I will go with the link you supplied tonight and let you know (lookslike it is a manual install... scary!!)
Thank you again for your support

carlyler

@ben999 if you have not already, read through the MySensors OH2 thread. I noticed a recent post by @TimO that talks about setting some permissions and that might be the issue. Otherwise, the manual install is not bad as he gives you step-by-step; I am a new to all this and managed to get it to work...

ben999

@carlyler

Thanks a lot for that hint... I remember reading that...

Either its not stated or I cannot see it, but i was wondering... Is this version 2 voor de rPi?
At the moment I am using MySensors version 1.5 with Pimatic as controller. And I would like to use v2.

ericvdb

@ben999 Yes, version 2

I feel a bit sorry to come back here for my own little troubles...

2- I followed tobof 's excellent step-by-step howto
3- I installed mysGateway
4- With pi@raspberrypi:~/MySensors $ sudo ./examples_linux/mysGateway -d i can see that my motion sensor and my RPi gateway get on well... they do speak to each other, right ?

Wrong serial port ?

Juste to make it clear : mysGateway bit of software is the magic that makes RPi believe that there's an arduino acting as a gateway on USB and collects the NRF24 info through GPio ?

Likely
/dev/pts/x are pseudo-terminals , not serial ports.

On my (old) Pi running Raspbian the serial port is /dev/ttyAMA0
You could run something like

dmesg |grep -i tty

to get an idea of serial ports on your Pi.

ben999

@Yveaux thanks a lot for your answer. Understanding linux is a slow and painful process

Here is the output from your command : dmesg |grep -i tty

What a mess...
ttyAMA0 is the one !!!
Thanks @Yveaux you got me on the right path !!! Goto next step!

I just did a fresh install of pimatic and MsGateway on the pi. But pimatic does not seem to get de messages. i started the gateway via the daemon method, is there a way to see if the sensor is reaching the gateway?

hausinger

@b0rmann
Do you still using the rs485 usb "dongle" to connect the rs485 nodes to the rpi? Do you attached some more nodes to your rs485 rpi Gateway?
Is it stable?
How do you do the configuration for it?

marceloaqno

@JahFyahh To view messages being exchanged with the sensors, run the gateway in debug mode:

mysGateway -d

JahFyahh

@marceloaqno thank you for the reply, I tried that and I receive "mysGateway: acce[t: Bad file descriptor" Any idea what this means?

marceloaqno

@JahFyahh Could you provide the full debug log?

manul

Hi team,

First of all, thanks for this amazing project and this doc.
I'm trying to use arduino nanos with Raspberry Pi 2 as a gateway: I can get it working when I configure the Raspberry Pi using serial gateway, however, it does not work using MQTT with latest version from git.
The error message is:
"mysGateway: accept: Bad file descriptor"

I followed all explanations given on this page.
Any idea?
Thanks again

marceloaqno

@manul Which MQTT broker are you using? Did you try to update it?

hausinger

I wanted to use the mysGateway with a USB/RS485 converter.

Here is my config: ./configure --my-gateway=ethernet --my-port=5003 --my-transport=rs485 --my-rs485-serial-port=/dev/ttyUSB0 my-rs485-baudrate=57600

make does it's job, but after i start the gateway it says:
mysGateway: Starting gateway....
mysGateway: Protocol version - 2.0.1-beta
mysGateway: MCO:BGN:INIT GW,CP=RSNG---,VER=2.0.1-beta
mysGateway: TSM:INIT
mysGateway: TSM:INIT:TSP OK
mysGateway: TSM:INIT: GW Mode
mysGateway: TSM:READY

after that it stopped to work.

Whats wrong in my configuration?

marceloaqno

@hausinger Have you checked if /dev/ttyUSB0 is receiving any data?

marceloaqno

The RPi port has just received a new update that changes some important things related to the location and name of the gateway binary and services:

mysGateway was renamed to mysgw
mysgateway service was renamed to mysgw

Now, after successfully running the make command, you will find the gateway file under ./bin/mygw

Also, before installing the new version you need to manually remove the old one:

If you are using systemd

sudo systemctl disable mysgateway.service
sudo rm /etc/systemd/system/mysgateway.service
sudo rm /usr/local/bin/mysGateway

If you are using sysvinit

sudo update-rc.d -f mysgateway remove
sudo rm /etc/init.d/mysgateway
sudo rm /usr/local/bin/mysGateway

@marceloaqno said:

Thank you for your answer. I don't know, how to check that? The wiring to my nodes is correct, the serial port is correct (dmesg says that).
Could you confirm, that my configuration from my last post is correct?

marceloaqno

@hausinger ~~Your configuration is correct~~. To check the serial, install the screen package (if you haven't already done so) and run:

screen /dev/ttyUSB0 57600

You should see some strange characters being printed.

~~I did a quick test here with your setup and found out that there is a bug with the gateway when the rs485 baud rate is set to 57600. With 9600 it works fine. I'll try to fix this.~~

marceloaqno

@hausinger You forgot "--" for my-rs485-baudrate=57600 in your configuration.
It should be:

./configure --my-gateway=ethernet --my-port=5003 --my-transport=rs485 --my-rs485-serial-port=/dev/ttyUSB0 --my-rs485-baudrate=57600

Hi @marceloaqno
Thank you for your answers. Yes, i saw this, but I did the "--", i forgot it in the last post, because I can't use copy & paste on my raspberry (remote Desktop).

Did this configuration work on your System?
Are you sure, that my configuration is ok? (with the "--")
Whats the normal behavior when i start the mysGateway with debug (mysGateway -d)? If i type the starting command in the terminal, the Gateway gives me the Messages (from my last post) and thats it (not more). I can now type a new command

I'm now not at home (Business trip), if I get home, i will try your "Screen" command

jmmorgan83

I followed the instruction above to make a mysgw file, but no file was generated.

mfalkvidd

@jmmorgan83 do you think there is any information you can share might help us help you?

jmmorgan83

I reset everything and ran it again. It did generate the file this time. Thanks, - Now to test it.

jmmorgan83

Has anyone gotten the raspberry pi gateway to work with Openhab on the same raspberry pi? I have both the virtual and mqtt gateways working, but I can get either one to communicate with Openhab.

So I'm at home today and make some Test.
The screen comand gives me some strange characters, thats ok I think.

But if i start the Gateway, I only get the same messages as shown in my other post.

Here are 2 Pics that show you, how it look like.

I also tried to make the gw with a baudrate of 9600, but still the same issues.!

PureGrain

Has anyone been able to get this to successfully work with a Vera?

RogerB68

Have been running MySensors for some time now with a EthernetGW running on Arduino. To clean-up the installation, I'm trying to get the Gateway running on my Raspberry instead but something stops the make process.

pi@raspberrypi ~/MySensors $ ./configure --my-gateway=ethernet --my-port=5003 --my-transport=nrf24                       [SECTION] Detecting target machine.

Any hints what I have done wrong ?

RogerB68

Issue solved, manual update of compiler from 4.6,3 -> 4.7.2 enables the make process. Similar problem also reported in post.

Using

sudo apt-get update
sudo apt-get upgrade

does not upgrade compiler. I used instruction according to How to upgrade GCC to 4.7+.

Tigroenot

@RogerB68 I had the same situation. I have removed the mtune parameter from the config file and compilation went fine. I don't know what it affects though.

jmmorgan83

I created a virtual serial port using this ./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway. I can see the port in the dev folder, but when I run dmesg I do not see it listed and therefore my openhab can not find it. How can I fix this?

marceloaqno

@hausinger After the command:

sudo ./bin/mysgw -d

It wasn't supposed to go back to bash, the gateway would wait for new messages.
I'm not sure what's going on with your setup because I tested your configuration options here and it worked.

marceloaqno

@jmmorgan83 You may need another name for the port, such as

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