💬 Building a Raspberry Pi Gateway

[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.

@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.

@marceloaqno

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:

   Any idea?

[mfalkvidd]

@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...

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 ?

@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

Thanks @Yveaux you got me on the right path !!! Goto next step! :smile:
