💬 Building a Raspberry Pi Gateway

Anticimex

@alowhum encryption is all or nothing. You can't leave one node without encryption if your gateway encrypts the messages it send.
And you will need to personalize your nodes to get the AES key into them. The documentation on security describes that process.

gohan

@alowhum if you put it in myconfig.h also on the arduino library you can just recompile the nodes and you are good.

Anticimex

@gohan not anymore. Only for pre 2.2.0 releases.

gohan

It is still working on mine

Anticimex

@gohan in other words, you use an old release

gohan

I can assure you I am using 2.2 from development as I am also running new driver. So unless you changed something in the last 3 weeks on the development branch it still works, unless the nodes are keeping the key saved.

Anticimex

@gohan have you verified your communications are actually encrypted?

Anticimex

@gohan If you see here, you will find that unless you use the simple password option, AES key is fetched from EEPROM: https://github.com/mysensors/MySensors/blob/28c4f3f19e7026f56fd9bbc61d566f770fd7a9d2/hal/transport/MyTransportRF24.cpp#L68
So either you are using the simple flag, nothing at all, or not using the key you think you use.

gohan

I ll have to check, but I put the key in the gateway myconfig.h

Anticimex

@gohan Perhaps on a rpi GW where there is no EEPROM, but I am talking about the nodes.

gohan

Well, if I have communication working it means the node should be encrypting data. I'll have to try with clear eeprom and try flashing sketch again

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.

rajeev2301

@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 ?

mfalkvidd

@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.

wes

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.

pepson

@macvictor
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!

Anticimex

Syna

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.

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.

sineverba

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

otto001

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

Nick Willis

@otto001 Thanks for that! I'm also getting this annoying service failure on 2.2 on a RPi 2. It seems to happen at random at night when nothing much is going on in the house. It probably happens once every 1 to 2 weeks.
CPU use is almost 100% and the service stops working.
Are there any logs I can check? I'd prefer to know what's wrong although I'll go with the auto restart on high cpu use to prevent the house from ceasing to function at random!

alowhum

I once noticed this too, on a pi zero system with domoticz beta.

otto001

@Nick-Willis:
I do run the gateway in debug mode, but I could not see anything special.
Yesterday the service was auto-restarted by my script:

2018-02-27 13:31:03 high CPU-usage! --> restarting service```

On the same time in the "normal" mysgw.log (debugging enabled) (should be syslog normally, but I changed the logfile location for better investigation):

Feb 27 13:30:36 raspiez mysgw: TSF:MSG:READ,14-14-0,s=1,c=1,t=23,pt=7,l=5,sg=0:0.11
Feb 27 13:30:36 raspiez mysgw: TSF:MSG:READ,14-14-0,s=3,c=1,t=0,pt=7,l=5,sg=0:21.9
Feb 27 13:30:36 raspiez mysgw: TSF:MSG:READ,14-14-0,s=4,c=1,t=1,pt=7,l=5,sg=0:31.4
Feb 27 13:30:38 raspiez mysgw: New connection from 192.168.1.11 <-- fhem re-connects
Feb 27 13:30:38 raspiez mysgw: GWT:TSA:C=1,CONNECTED
Feb 27 13:31:04 raspiez mysgw: Received SIGTERM <-- AUTO-Restart

The only thing that is a little bit unusual is the re-connect of my controller (fhem) - but this happens every 30 minutes for stability reasons.
This should not happen, but I can not find out what the problem is.

Maybe you could also enable debugging by changing the following file (maybe we can find a pattern why this is happening):

/etc/systemd/system/mysgw.service

from

ExecStart=/usr/local/bin/mysgw

to

ExecStart=/usr/local/bin/mysgw -d

Please do not forget to issue a

sudo systemctl daemon-reload

followed by

sudo systemctl restart mysgw.service

to enable the change.

My restarting-script might help until someone with better knowledge finds a solution...
I also will have an eye on the logs for findig out how often this is happening...

Cheers,
Otto

marceloaqno

Please, could all of you who experienced this issue post the configuration options you used to build the gateway?
This would help to investigate the problem.

otto001

@marceloaqno : of course, thanks for the hint!

I had the following configure:

./configure --my-transport=nrf24 --my-rf24-irq-pin=15 --my-gateway=ethernet --my-port=5004

(The high CPU problem also occured before I connected PIN 15 to IRQ without the corresponding config option. I hoped to solve the Problem using IRQ, but this did not help. And I have a second GW with default port 5003 in my network. This is running an ancient version of Raspi GW Software and this is working fine -but slower). I am using current fhem as controller and I have it connecting every 30 minutes to the gateways due to stability issues in the past. There are only about 6 nodes (just motion, humidity & temp and lux) connected to this gateway.

In addition to that I changed the default channel in MyConfig.h (because I have two different MySensor networks):

#ifndef MY_RF24_CHANNEL
#define MY_RF24_CHANNEL (82)
#endif

I am pretty sure, that this is not important, but I also set up rsyslog to write gw logs to an own file instead of syslog....

Maybe this helps.

Cheers,
Otto

marceloaqno

@otto001 I think I found the problem. I wrote a fix for it:
https://github.com/marceloaqno/MySensors/commit/ca8865d8e1fe1b08195943fae1640d5fddb81924

otto001

@marceloaqno : Wow, you are fast! Thanks!
Just applied the patch and recompiled. I will report in a couple of days while my monitoring-script is still running (and logging)...

Cheers,
Otto

mvader

@marceloaqno I am also recompiling and testing.
thanks for the (hopeful) fix
I will report back with my status in a few days

otto001

@marceloaqno :

At first, THANKS for your help. CPU usage does not rise anymore.
But unfortunately no more node READs after the same situation:

Mar  4 07:00:09 raspiez mysgw: TSF:MSG:READ,14-14-0,s=255,c=3,t=6,pt=1,l=1,sg=0:0

Mar  4 07:00:37 raspiez mysgw: GWT:TSA:C=1,DISCONNECTED

After this point (again after a reconnect from the controller) no more messages from any node PLUS the cpu usage stayed normal (what makes it even worse at this moment, as I would have to create a script which monitors the logfile and restarts the mysgw service in this situation). As soon as the service is restarted, everything is working fine again.

What happens after this point in the log:

Mar  4 07:00:37 raspiez mysgw: GWT:RFC:C=0,MSG=0;0;3;0;2;

and so on....

It seems that the increasing cpu usage is only a symptom for the real problem.
As I am using this in production I will dis-apply the patch and use the daemon as before (beacuse using the python script for cpu-usage-monitoring makes the situation somehow controllable for me).
Maybe you could have an additional eye on this please? Could I help you with further information? Maybe I could add some additional logging somewhere in the code?

Thanks again and cheers,
Otto

@otto001 I'm trying to reproduce this problem, but so far I've got nothing beyond the normal behavior of mysgw.
I tried with a RPi1 and RPi3 using the fhem controller with the latest raspbian.

mvader

@marceloaqno said in Building a Raspberry Pi Gateway:

@otto001 I'm trying to reproduce this problem, but so far I've got nothing beyond the normal behavior of mysgw.

My uptime is at 4 days now. so far still working with your patch. CPU is at 2% and sensor network still working correctly. will report if that changes.

Nick Willis

I've been using your restarting method and its been working ok and has done one restart in 5 days.
However I now see something else where altho cpu use is fine, none of my nodes can communicate to the gateway. My controller can connect to the gateway no problem but there are no messages received. Restarting nodes does not help. Only a manual restart of the gateway gets things going again - at least for a while anyway.
Where is the log output from the gateway to be found? I know it can be run from the bash prompt to write the output to screen but how about logging the installed service output?

mfalkvidd

@nick-willis the log is sent to syslog by default. See https://www.mysensors.org/build/raspberry#troubleshooting for details.

otto001

@marceloaqno : This is strange. I am using a RPi 1 on this gateway with raspbian Jessie. Beside the GW-service there is only a small python programm which listens on an UPD-Port and plays an mp3 if it receives suitable data (for doorbell). Since March 4, 20:15 there were several restarts due to high cpu usage (after dis-applying your patch):

2018-03-04 23:01:03 cpu (99.7) very high! --> restarting service
2018-03-05 07:31:03 cpu (99.7) very high! --> restarting service
2018-03-05 11:01:03 cpu (98.7) very high! --> restarting service
2018-03-05 13:31:04 cpu (94.7) very high! --> restarting service
2018-03-06 11:31:03 cpu (99.7) very high! --> restarting service
2018-03-06 12:31:03 cpu (98.7) very high! --> restarting service
2018-03-07 06:01:03 cpu (94.8) very high! --> restarting service
2018-03-07 22:31:03 cpu (99.8) very high! --> restarting service

With this "auto-restarts" the sensors are working fine, I did not notice any problems.

However, I just upgraded to the recent Stretch (what takes a LONG time on RPi 1 and made me struggle a little bit with the new network names). I also rebuilt the GW of course and will report here what will happen....

@Nick-Willis : did you apply the patch of marceloaqno or not? Did you enable debugging? (see here )

Cheers,
Otto

marceloaqno

@otto001 In a new attempt to trigger this problem, I am using a script that will force the fhem controller to reconnect every 30s to the gateway (built with mysensors master branch, unpatched), and sends me a note in case of high CPU usage:

I'll leave it running for a few days to see what happens.

Here is the script, if anyone is interested:

#!/bin/sh

while true; do
  (echo "set mysgw disconnect"; echo "quit") | telnet localhost 7072 > /dev/null 2>&1
  sleep 1
  (echo "set mysgw connect"; echo "quit") | telnet localhost 7072 > /dev/null 2>&1
  sleep 1

  cpu_percent=$(ps -C "mysgw" -o %cpu=)
  cpu_percent=${cpu_percent%%.*}
  if [ "$cpu_percent" -ge 90 ]
  then
    echo "ALERT: HIGH CPU USAGE"
    # pushbullet script from https://gist.github.com/outadoc/189bd3ccbf5d6e0f39e4
    /home/pi/pushbullet.sh "RPi1: HIGH CPU USAGE"
    exit
  fi

  sleep 30
done

otto001

@marceloaqno : Thank you!
Just a notice: I do NOT disconnect, I just connect every 30 minutes. Has been working for me since more than 2 years (ancient ms-gw version on RPi).

Yesterday I did a dist-upgrade to stretch on the "problematic" gw (as mentioned above) - without your patch but with my monitoring-script running. It is a little bit to early I presume, but no high cpu problems so far. I will report back here in a few days. Maybe this problem is really related to old libraries or something?! If this is running stable for a few days I will apply your patch and see what happens.
Thanks again!

Cheers,
Pula

marceloaqno

@otto001 After a few hours running the reconnect script, I noticed several error messages in my gateway log:

accept(): Too many open files

The problem was that the gateway wasn't releasing the socket descriptor after each disconnection of the controller. After reaching the limit (mine was 1036) the controller can't connect.

I'm not entirely sure that this problem is related to what you're having. You can check how many file descriptors currently opened by the gateway with the command below

sudo lsof -u root |grep mysgw |wc -l

The fix:
https://github.com/marceloaqno/MySensors/commit/a40d4441b7460225100398ff6f2581c2b0df36ea

How do I update from master branch to development branch?

gohan

Why do you want to do that? Development version is still work in progress

I'm using a raspberry pi gateway in home-assistant.
Sometimes my gateway doesn't work anymore, and when I restart the service, it is running good
I used ./configure --my-transport=nrf24 --my-rf24-irq-pin=15 --my-gateway=ethernet --my-port=5003

gohan

Read the article again, there is the instruction on how to download the development version, but before you have to uninstall the mysgw service and rename the current mysensors folder to keep as backup.

marceloaqno

@gieljnssns The fixes I mentioned above haven't yet been applied to the development branch. Eventually they will be, but I'm still doing some testing.

otto001

@marceloaqno :
Thank you!!! Should this patch be applied together with your first patch?
Interesting:
After some days without problems on the newest raspbian packages the gw hung again, but WITHOUT high cpu usage (and WITHOUT your first patch applied). There were just no more reads from the sensors in the log, only the re-connects of fhem. After restarting the service, everything is fine again.
Unfortunately I did see your post after that
But I checked the log and could not find the words "too" or "Too" in the log (running service with -d).
Some minutes after restarting I checked how many open files there were with the command you supplied: 21

In the meantime I have created a small udp listening service which restarts the service if a certain string is received, so I can restart the service by double-clicking one of my switches without the need of login to the gw (also for the wife)....

@gieljnssns : I think you are experiencing exactly the same problem we are discussing

Thanks again!
Cheers,
Otto

gohan

I'm using dietpi and I am not having big issues even running 2 gateway instances with 2 different radios

marceloaqno

@otto001 The second patch can be applied without the first one.

otto001

@gohan :
dietpi looks interesting! did not know about this yet.
what hardware are you using? and what version of mysgw?

otto001

@marceloaqno :
THANKS! Just applied your patch.
I will report in a few days when I can see if the problem is solved...
Cheers,
Otto

Can someone tell me how to apply this patch?

I have checked mosquitto has correct user-pw combination, but what should I check next? Help!

@masmat said in Building a Raspberry Pi Gateway:

--my-mqtt-client-id=mygateway1

Do you have another client named mygateway1 connecting to mqtt? Try changing it to a different name just to play safe

MasMat

@gohan Can I just edit mysgw.cpp and do "daemon-reload"?
I have just this one gw. And openHab2 but that has a different id.

gohan

No, you need to recompile it again in case you make that change. Have you ever tried dietpi for RPI?

MasMat

@gohan OK. I did that, the same socket error remains in Mosquitto just under new id.
Is my syntax correct or am I somehow having problems with mosquitto user-pw...?

Haven't tried DietPi. Would Mys+Mosquitto+Openhab2 have trouble running on it? Or why should I change to it?

gohan

have you tried connecting with another mqtt client like mqttfx to see if everything is working?

marceloaqno

@masmat What is the mqtt broker / version you are using?

marceloaqno

@gieljnssns One way is to replace the changed files, in this case EthernetServer.cpp for the first patch and EthernetClient.cpp for the second patch.

You can download from:
https://raw.githubusercontent.com/marceloaqno/MySensors/linux-fix-stability/drivers/Linux/EthernetServer.cpp
https://raw.githubusercontent.com/marceloaqno/MySensors/linux-fix-stability/drivers/Linux/EthernetClient.cpp

Here is a step-by-step:

git clone https://github.com/mysensors/MySensors.git
cd MySensors
curl https://raw.githubusercontent.com/marceloaqno/MySensors/linux-fix-stability/drivers/Linux/EthernetServer.cpp -o drivers/Linux/EthernetServer.cpp
curl https://raw.githubusercontent.com/marceloaqno/MySensors/linux-fix-stability/drivers/Linux/EthernetClient.cpp -o drivers/Linux/EthernetClient.cpp

from here just run ./configure with your options and then make

MasMat

@marceloaqno Mosquitto v1.4.14.
The broker is working, at least sending & receiving command line (_sub & _pub) messages.

@gohan

Can you provide some installation instructions for dietpi?
I will try this...

gohan

just download the image and do the same as a Raspian image. I haven't tried mqtt gateway yet, so I don't know if it may be a gateway bug or else.

otto001

@marceloaqno :
Hi, unfortunately the latest patch did not work for me.
Still the gw stops receiving, but without high cpu usage
Fortunately I can restart the gw now using a button and this udp-scripts

Of cource I could give dietpi a try, but I would think, that a general solution would be better (for other users as well)

cheers,
Otto

MasMat

@gohan I had another sd card and tried a ready image of DietPi with Mosquitto pre-installed.
I tried it without user/password and mosquitto accepting anonymous but:

/var/log/mosquitto/mosquitto.log:

mvader

1st patch is still working good for me. have had no issues since applying it.

question. is it normal/correct for the gateway to ping or spam? every 10 seconds i see the gateway announce it's version.
its not doing the full restart or anything.. just giving the 2.2.0 every 10 seconds.

gohan

@masmat have you tried with ethernet gateway? If I have time I'll try the mqtt this weekend

@mvader I never noticed that.... is it the mqtt GW?

MasMat

@gohan How would I interface the rest of my HA without MQTT...that's at the center of my plan really

gohan

I think OH should support it, but I was just asking to make a test.

MasMat

@gohan I configured:

The controller doesn't exist on the DietPi card yet but I'm not sure if that's causing the problem.

@masmat said in Building a Raspberry Pi Gateway:

remove that parameter as it is not needed for ethernet

marceloaqno

@masmat I did a test with the following configuration:

@marceloaqno any ideas about that?

@mvader oh, that's normal. I though you meant something else

otto001

Yesterday I cloned the latest version on a recent raspbian (9.3) and I applied the first patch of @marceloaqno .
We will see. So long there were no problems. I will send an update in a few days...
As a last help I could switch to mqtt and do a restart after a defined amount of time (if no events are received)....

Cheers,
Otto

gohan

@marceloaqno I got my gw rfm69 gateway suddenly stopped communicating with nodes. I tried everything to reinstall it but without luck. I was able to have it running on my test rpi with a complete OS reinstall. Is there anything else I need need to clean up from my install to reset every settings? (besides the mysensors folder and mysensors.dat file I already deleted)

romeo01

How can I monitor the traffic data between the raspberry and RF module (NRF24L01) on a Ethernet gateway ??

My gateway is built for Ethernet. I start the gateway with "service mysgw start"
Now, I would like to get the same data output than output debug (./bin/mysgw -d) but without stop mysgw service.
I need to use MYSController as Ethernet client at the same time.

Thanks

mfalkvidd

@romeo01 see instructions at https://www.mysensors.org/build/raspberry#troubleshooting

MasMat

@marceloaqno What does your mosquitto.log show?
I did a fresh install of DietPi (stretch), Mosquitto and MySensors --branch master. I left out everything and pretty much did the configure command as you did. I get the same result, but mosuiqtto log shows:

1521584708: New connection from 127.0.0.1 on port 1883.
1521584708: New client connected from 127.0.0.1 as mygateway1 (c1, k15, u'masi').
1521584733: Socket error on client mygateway1, disconnecting.
1521584778: New connection from 127.0.0.1 on port 1883.

So is this normal?
I have one sensors built that's not connecting (its log shows it just trying and trying..). I would like to user simple password and the LEDs, I will build one extra sensors just to help testing.

otto001

@MasMat : what does your mysgw.log show?

romeo01

@mfalkvidd Thanks fer info, now I can see the serial protocol as well in the syslog. Next step should be to have a logfile dedicated to mysgw.

otto001

@MasMat : I just forgot, that I reconfigured rsyslogd to log mysgw to a different file. syslog is correct.

I do not use mqtt for mysensors yet, but the syslog seems good?

Richard van der Plas

Was pointed here from another post, having serious issues with high CPU utilization op the gateway, is there any workaround and the moment?

its not a high traffic gateway (around 10 sensors connected of which 5 updating every 15 minutes)

mfalkvidd

@richard-van-der-plas the best workaround so far is in the post I linked to.

marceloaqno

@mvader The gateway will respond with an I_VERSION every time a controller connected to port 5003 sends an I_VERSION request.

marceloaqno

@gohan Sorry to hear that, mysgw doesn't change any system files, a simple reboot and rebuild of the gateway should be enough to resume communication in a case of more serious error.

marceloaqno

@masmat This is my mosquitto.log

shows only if I stop/exit mysgw.

MasMat

@marceloaqno OK, I will look into that once I have an extra sensor feeding my gw (the one I built is a little complex and could be buggy).

Another question: I configured mysgw without "simple password" to sort out problems.
Now to reconfigure mysgw I have to run the "./configure --blah --blahblah..." command and "make", but do I also have to do "make install"? And do I have to re-start & enable the service? Should I stop it first also? Anybody got a step-by-step for this?

gohan

You could also make a simple node running mock mysensors sketch that can simulate a working sensor, if you need some data running through the gateway. When I recompile the gateway I usually stop the service, uninstall the mysgw service and do the make and make install. I don't really know if it is actually required but I like to keep things clean

marceloaqno

The two patches to fix ethernet stability have been merger into the development branch, and also some changes to the gateway logging. I updated the build instructions to reflect the changes.

MasMat

@gohan I made a sensor that sends DHT11 temp+hum. This is the output (some of it..) from mosquitto_sub to topic mysensors-out. So I appear to have a something working. OpenHab2 is not finding any items still...

Once I changed the config to include simple password, it's not showing anything anymore in mosquitto_sub
It would appear that something is missing from my setup or there's a bug in the configure-line. Can someone tell if there's a bug here somewhere:

sudo ./configure --my-transport=nrf24 --my-rf24-irq-pin=15 --my-signing=password --my-signing-password=ZZZZZZ --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-user=XXXXXX --my-mqtt-password=YYYYYY --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1 --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18
