MySensors Raspberry port suggestions

@raptorjr
In the current state, serial gateway on RPi can only use a "real" serial port like /dev/ttyAMA0 (gpio pins) or (if an arduino is connected or a USB->Serial adapter) /dev/ttyACM0. To use PiDomo you will need to put an Arduino to the mix.

@marceloaqno

Thank you. I'll have to wait for pseudo tty or for PiDome to get support for Ethernet gateway.

marceloaqno

@raptorjr
I think PiDome also supports MQTT Gateway. Did you try that?

raptorjr

@marceloaqno

I don't really understands what MQTT is and how to use it. But maybe I'll try that. Would like to see how PiDome works and if I like it better than Domoticz.

marceloaqno

@raptorjr PiDome should work now (https://forum.mysensors.org/topic/2389/added-support-for-local-mysensors-rpi-direct-radio-connection).

You need to add --my-serial-is-pty when running ./configure or uncomment the line #define MY_IS_SERIAL_PTY in mysGateway.cpp.

raptorjr

@marceloaqno

Wow. That was fast work =)

Trying it now and the /dev/ttyMySensorsGateway is created. Followed the guide in the link you provided. Everything goes great until the last step. I don't see the message "Gateway startup complete". So I don't know if I have any communication between PiDome and the gateway?

I'll start reading forums and see if I can find a solution. Or if I missed something.

@marceloaqno I've got the MysGateway configured and built to be an MQTT Gateway. I have a node (MySensors v2.01) sending temperature, humidity and voltage data to the Gateway. Looking at the stdout on the Raspberry Pi I can see that the information is being correctly received but there seems to be a problem with the published messages. I'm getting "send: Broken pipe" messages. I've copied and pasted some of the MysGateway stdout terminal output below. Do you have any insights on what might be going wrong?

Thanks very much

@marceloaqno

I think there may be a memory leak in the gateway. While using it as a ethernet gateway I loose about 100Mb every day, if my only node is turned on. After a few days I can't even login with SSH and need to remove the power to my Pi3 to reboot it.

If I turn off my node, memory usage is normal. So it seems to have something to to when messages is received/transmitted. Is there anything I can do to get more details where the problem could be?

I'm using the image from Domoticz where everything is installed, and have only added mysGateway.

marceloaqno

@raptorjr @hawk_2050 I'll check.
@b0rmann I'll do something about it.

@marceloaqno Hi, could you please explain to me what the steps are to compile it for RPi3?
I went here - https://github.com/marceloaqno/Raspberry
Downloaded and tried to compile. The following error has come up:

OK, I manage to install it finally.

However, again I have a problem:

./configure --my-gateway=ethernet --my-rf24-channel=1 --my-rf24-pa-level=RF24_PA_MAX --my-controller-ip-address=127,0,0,1

when I start it I have the following in the log:

Add some options to the gateway execution:

# ./examples_linux/mysGateway -h
Usage: mysGateway [options]

Options:
-h            Display a short summary of all program options.
-d            Enable debug.
-b            Become a daemon.

Debug is now disabled by default.
You can't run it as a linux daemon if debug is enabled.
When daemonized all messages will be print to syslog.

@marceloaqno Interesting. When I execute "mysGateway -h" I get the following:

pi@m:~/MySensors/examples_linux $ mysGateway -h
MCO:BGN:INIT GW,CP=RNNG---,VER=2.0.1-beta
TSM:INIT
Segmentation fault

What does "Segmentation fault' mean please?

marceloaqno

@alexsh1 You must be root to run the gateway:

$ sudo mysGateway

It seems that you are not using the latest version, -h should have shown you the options list.

alexsh1

@marceloaqno I have the latest version (downloaded yesterday). Thanks very much for your help. I got the following:

pi@m:~/MySensors/examples_linux $ sudo mysGateway -h

The RF communication is fine, but I do not understand why Domoticz is not assigning ID.......

EDIT: I can see in Domoticz in the Hardware section:

MySensors Gateway with LAN interface
Version: ? Setup

Typically ? comes up when the controller is not recognised or not connected

EDIT2:Deleted and started fresh. Unfortunately, now the log file is flooded with the following:

@alexsh1 There is a bug with --my-controller-ip-address, I'm not sure if it's your case, but try to avoid it.

I tried Domoticz here and everything seems fine:

MySensors Gateway with LAN interface
Version: 2.0.1-beta (Setup)

I recommend you to start from scratch, re-download the gateway from here:
https://github.com/marceloaqno/MySensors/tree/dev-raspberrypi

alexsh1

@marceloaqno OK, this must be the reason. I have tried the serial setup and it worked with a little tweak:

/dev/ttyUSB20 -> /dev/ttyMySensorsGateway

For whatever reason Domoticz did not see ttyMySensorsGateway so I had to create ttyUSB20
