MySensors Raspberry port suggestions

[marceloaqno]

@lafleur Do you recommend any RFM69h library that works well in Pi? I could try to add support if there is any.

[lafleur]

There are a number of ports to the RPI...

and others...

Thanks

[marceloaqno]

Just an update, I've been using this port on my raspberry pi during the last months and it has been quite stable, the code is also up to date with the mysensors development branch.

[emc2]

That's great, thanks @marceloaqno

I just started testing but I had to revert to 7d51087e589afb1296e71442fe2164807da399ef to have it working.
Last commit SEGFAULT after

Eth: Listening for connections on 0.0.0.0:5003

Also, do you have an updated initscript to launch it automatically at boot? It seems the one from the old PiGateway is not working very well with this one. For now I just added a cronjob.

[marceloaqno]

@emc2 Could you give more information about your setup? I wasn't able to reproduce the error.

For the initscript, I will try to add an updated version for systemd.

[emc2]

So I did a few tests, one of my setup is working on the last commit, the other not. Both are model B.

• Working Pi:
  Domoticz image, upgraded and up to date wheezy

• Commit 7d51087e589afb1296e71442fe2164807da399ef Pi:
  Regular (non-Domoticz) old wheezy image updated to jessie

All are up to date for all package on apt and firmware is up to date for rpi-update

Linux domoticz 4.4.15+ #897 Tue Jul 12 18:38:58 BST 2016 armv6l GNU/Linux

My bet is that my "non-working" Pi, wich is also my guinea pig Pi, is missing a dependency or something. Let me know if I can get you some logs to troubleshoot, but it may be very specific to this setup so may not be worthwhile investigation unless a common factor start to emerge.

Anyways, thanks for the port! :+1:

very nice fork. but... i can't compile it:

and more, more similar errors. with --my-gateway=ethernet compiled fine

[marceloaqno]

@b0rmann It should work now. Thank you for reporting this.

[ericvdb]

Do I get it right that this is a RPi gateway with directly connected RF24L01+ tranceiver with support for both ethernet and MQTT?

If so, is there a guide somewhere on how to set this all up?

[marceloaqno]

@ericvdb That's right. I hope to add support for RFM69, Serial and software signing very soon.

To use, clone the raspberryPi port for MySensors 2.0:

git clone https://github.com/marceloaqno/MySensors.git
cd MySensors

To configure it, take a look at the options available within configure:

./configure --help

For other options, you may have to edit the sample file example_linux/mysGateway.cpp, and uncoment what you need.

Once done, run:

make
sudo make install

To run the gateway you need to be root or use sudo:

sudo msyGateway -h

For wiring, follow this guide:
https://forum.mysensors.org/topic/2437/step-by-step-procedure-to-connect-the-nrf24l01-to-the-gpio-pins-and-use-the-raspberry-as-a-serial-gateway-mysensors-1-x

[ericvdb]

@marceloaqno thanks, will try this asap. What about the status leds, is that supported?

[marceloaqno]

@ericvdb sorry, no support for status led.

@b0rmann Fixed a bug with the config file. Please remove your MySensorGateway.cfg and let the gateway re-create it.
Also the default config file name was changed to /etc/mysensors.dat

For the routing problem, do you have the output from the nodes that are communicating with the gateway?

[b0rmann]

@marceloaqno

it was not a problem with the routing, but the powering nrf24 from 3v3 rpi output. It solved a separate power source

I'm trying to get this to work, and it looked good. But after a day of running my Pi3 with Domoticz stopped answering to anything. Couldn't even connect with SSH.
So now I need to start to troubleshoot. But I wonder if mysGateway produces a log somewhere? And where can I find the MySensorGateway.cfg? It is not in /tmp.

After restart of the Pi3 I always get a error from Domoticz about not being able to send the command, although it does get through anyway.
Don't know if mysGateway is the problem, but I need to gather all the logs I can find to figure it out.

[marceloaqno]

@raptorjr MySensorGateway.cfg was renamed to mysensors.dat in the last version. The default directory that the gateway keeps the file is /etc. The file is used mostly to keep the nodes routes, so you won't find anything useful there. Which linux distro/version you're using in your RPi?

[raptorjr]

@marceloaqno

Thank you. I thought that the .cfg file contained some information about a log file, but now I know it's purpose =)

I'm using a SD card image I found at the Domoticz site, preinstalled with Domoticz.

Linux raspberrypi 4.1.18-v7+ #846 SMP Thu Feb 25 14:22:53 GMT 2016 armv7l GNU/Linux

The problem could be with Domoticz also, but since I thought that mysGateway is still kind of beta I would start to look for the problem there.

Now I found a entry in the Domoticz error log:
2016-08-26 19:31:00.663 Error: Gateway hardware (4) thread seems to have ended unexpectedly

So it seems that something maybe happened with the mysController. Maybe not died, but stopped answering and locking the whole Pi?
Or if that error refers to some internal Domoticz gateway thread.

@raptorjr you could try to pipe the gateway output to a file starting it manually:

sudo mysGateway &> /tmp/mysensors.log &
