💬 Building a Raspberry Pi Gateway

[Anticimex]

@gohan not if there is no encryption at all. You could try to use simple password option on a node with various passwords and see if it is detected by your gw at all.

[gohan]

@anticimex I guess you were right... the gw and node aren't using the AES key. So where am I supposed to add it in the gateway?

[Anticimex]

@gohan you set that with the configure arguments I suspect, but I can't see it in the documentation. @marceloaqno perhaps knows how the rPi port handles this. I'm on a phone so I can't check the code easily. But you should be able to find it in the transport driver for rPi. On the rPi it can probably be defined in the code as it does not have a personalizer.

[gohan]

@anticimex It doesn't read it from the mysonfig.h for sure as it is where I always put it

[Anticimex]

@gohan MyConfig.h does to my knowledge not have a define value for that. You cannot add new definitions to it and expect them to have an effect. If there is one already defined in there, as a comment or not, and it does not have an effect, please report a bug on it.

@macvictor
I followed all the step that you mentioned in your post to establish the serial gateway. However I am still not able to receive the message from arduino. Could you please what to do?

import RPi.GPIO as GPIO
from lib_nrf24 import NRF24
import time
import spidev

GPIO.setmode(GPIO.BCM)

pipes = [[0xE8, 0xE8, 0xF0, 0xF0, 0xE1], [0xF0, 0xF0, 0xF0, 0xF0, 0xE1]]
radio = NRF24(GPIO, spidev.SpiDev())

radio.begin(0,8)

radio.setPayloadSize(32)
radio.setChannel(0x76)
radio.setDataRate(NRF24.BR_1MBPS)
radio.setPALevel (NRF24.PA_MAX)
radio.setAutoAck(True)
radio.enableDynamicPayloads()
radio.enableAckPayload()
radio.openReadingPipe(1 ,pipes[1])
radio.printDetails()
radio.startListening()
radio.GPIO.cleanup()

Please find below my raspberry code..can you please suggest , if there is any issue with code or am I missing anything ?

@rajeev2301 please don't split our effort to help you into multiple threads. It wastes people's time when some information is in one thread and some in another thread.

To upgrade to the latest release, can I use git pull, or is it better to delete the directory and start again?

[Anticimex]

@wes you can pull. Just as long as you verify that your working directory is clean or only contains changes you intend to have. And you have the appropriate branch or tag checked out.

Hi
Is any chance to add security & signing for radio RFM69HW ? Please help me how ?

[Anticimex]

@pepson signing is radio agnostic. It has nothing to do with the radio.

[sineverba]

@anticimex @wes Can I please ask how to update? I mean, the right command to type.
I have the folder "MySensors" on documents of my user in Pi:

/home/sineverba/MySensors

Of course I have all installed and perfectly working now (I'm on the 2.2.0 rc2).

I need also to relaunch the ./config command?

Thank you to both and all!

Hello, I configure the raspberry gateway to use MQTT. I set mosquitto as the broker. The problem that I encounter is that when I subscribe to test if the gateway publish on the broker, I have empty message. So my first guess is that there is an issue somewhere which cause that only empty message are sent.

Here is my arduino code : https://pastebin.com/YKi4EAad
The RasperryPI3 config & logs : https://pastebin.com/Kjn8CC8A
The MQTT Client logs : https://pastebin.com/ZP8GrkTj

[Sergio Rius]

Regarding the communication issues described in the instructions page with the 2.2 stable version, is that still valid and still recommended to use the development branch?

[gohan]

Go for stable now, I need to remove that line from the page

[Sergio Rius]

@gohan Thank you verys muchos. :+1:

[marceloaqno]

@syna It is empty because it's a message of type I_ID_REQUEST that your node is sending. You need to set up a controller to distribute IDs or you can set it manually by adding this to your node's sketch:

#define MY_NODE_ID X

where X is a unique number from 1 to 254.

Hi to all,
tonight I made update from 2.2.0 RC2 to 2.2.0 (stable) on my Raspberry PI3.
It is a live system (my heater control).

By the way the update is very simple.

First of all, backup or better CLONE your PI.

1 - Disable the daemon with

sudo systemctl stop mysgw.service && sudo systemctl disable mysgw.service

2 - Make a copy of the MySensors folder ( I made a copy with the name of version coming, so...)

cp -r MySensors MySensorsX.X.X(rc2)/

(the slash at the end means "It's a folder!"

3 - Remove the MySensors folder

sudo rm -r MySensors

4 - Git the "new" MySensors folder && configure it as usual. Remember to activate the daemon and see on Domoticz (for example) the gateway with new version :)

Hi,

I am running the current version (2.2.0) on a RPi 1.
I noticed that sometimes the cpu usage of the service is increasing dramatically (around 90% and more) - and then the service stops working.
As I am not a C-Pro, I wrote a little python-script, which is called every minute by cron and restarts the service, if it uses more than 50% cpu.
Maybe someone will find it useful:

# -*- coding: utf-8 -*-
import psutil, sys, os, datetime

PY3 = sys.version_info[0] == 2
LOOKFOR = u"mysgw"
for proc in psutil.process_iter():
    if proc.name() == "mysgw":
        dt = str(datetime.datetime.now()).split('.')[0]
        #print(proc)
        cpu = proc.cpu_percent(interval=1)
        #print(cpu)
        #print(proc.cpu_times())
        if cpu > 50:
                print(dt + " high CPU-usage! --> restarting service")
                os.system("/bin/systemctl restart mysgw.service")
        else:
                if datetime.datetime.now().strftime('%M') == "45":
                        print(dt + " everything OK, cpu: " + str(cpu))

and the crontab-entry (as root):

* * * * * /home/pi/pstest.sh >> /var/log/mysgw-logger.log

Cheers,
Pula
