💬 Building a Raspberry Pi Gateway

[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.

When running as a service, is there a way to watch the debug log?

[Patrik Söderström]

Any ETA on support for RFM69 ? Need to extend my coverage :)

[alesc]

Done:

1. git clone https://github.com/mysensors/MySensors.git
2. ./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
3. make.
   Got error:
   In file included from ./MySensors.h:287:0,
   from examples_linux/mysGateway.cpp:70:
   ./drivers/RF24/RF24.cpp: In function âuint8_t RF24_spiMultiByteTransfer(uint8_t, uint8_t*, uint8_t, bool)â:

   *ptx++ = NOP ;
   ^
   Makefile:46: recipe for target 'examples_linux/mysGateway.o' failed
   make: *** [examples_linux/mysGateway.o] Error 1
   Any idea?

@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.

EDIT: Sorry, that won't work because the Raspberry Pi stuff didn't exist when MySensors 2.0 was released. You'll have to do git pull instead, to get tekka's fix.

@alesc @mfalkvidd Thanks for reporting, fixed: https://github.com/mysensors/MySensors/pull/635

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
Smashing
Thanks a lot for that hint... I remember reading that...
Linux is so damn rigid :laughing:
Thank you again for your help

[JahFyahh]

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

[ben999]

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

1- So i installed openhab2 on RPi3 with a fresh SDCard
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 ?

mysGateway: Starting gateway...
mysGateway: Protocol version - 2.0.1-beta
mysGateway: MCO:BGN:INIT GW,CP=RNNG---,VER=2.0.1-beta

mysGateway: TSF:MSG:READ,1-1-0,s=1,c=1,t=16,pt=0,l=1,sg=0:0

5-in things/demo.things" I put this.

Bridge mysensors:bridge-ser:gateway [ serialPort="/dev/pts/2", sendDelay=200 ] {  }

Right away, it worked (king of the world!) and i could see that bridge in paperUI !!!
But i got that after a reboot of RPi

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 ?

[Yveaux]

@ben999 said:

Wrong serial port ?

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 :laughing:

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! :smile:

[JahFyahh]

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
