💬 Building a Raspberry Pi Gateway
-
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?
-
@nick-willis the log is sent to syslog by default. See https://www.mysensors.org/build/raspberry#troubleshooting for details.

@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 serviceWith 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

@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
-
@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

@otto001 After a few hours running the reconnect script, I noticed several error messages in my gateway log:
accept(): Too many open filesThe 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 -lThe fix:

-
How do I update from master branch to development branch?
-
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
-
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.
-
@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.
-
@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: 21In 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
-
I'm using dietpi and I am not having big issues even running 2 gateway instances with 2 different radios
-
@otto001 The second patch can be applied without the first one.
-
@gohan :
dietpi looks interesting! did not know about this yet.
what hardware are you using? and what version of mysgw?
-
@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?

@otto001 normal rpi3 and mysgw 2.2

I need help with my Rpi mqtt-gw.
I tried to get dev-branch working but changed now to stable. All the install routines run without problems. The service just doesn't seem to work and I can't figure out why.- Rpi W, Raspbian wheezy, nRF24-PA, MQTT-gw, Mosquitto and Openhab2 on same board

@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
-
@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.
-
No, you need to recompile it again in case you make that change. Have you ever tried dietpi for RPI?
-
@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?
-
have you tried connecting with another mqtt client like mqttfx to see if everything is working?
-
@masmat What is the mqtt broker / version you are using?
-
@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.cppHere 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.cppfrom here just run ./configure with your options and then make
-
@marceloaqno Mosquitto v1.4.14.
The broker is working, at least sending & receiving command line (_sub & _pub) messages.
-
Can you provide some installation instructions for dietpi?
I will try this...
-
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.
-
@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-scriptsOf 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

@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:
1521141160: Socket error on client <unknown>, disconnecting.

-
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.
-
@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?
-
@gohan How would I interface the rest of my HA without MQTT...that's at the center of my plan really
-
I think OH should support it, but I was just asking to make a test.
-
@gohan I configured:
./configure --my-transport=nrf24 --my-gateway=ethernet --my-controller-ip-address=127.0.0.1 --my-rf24-irq-pin=15 --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18 --my-signing=password --my-signing-password=ZZZZZZ./bin/mysgw -d:

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

@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)
-
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

@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.
-
@MasMat : what does your mysgw.log show?
-
@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.

@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?

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)
-
@richard-van-der-plas the best workaround so far is in the post I linked to.
-
@mvader The gateway will respond with an I_VERSION every time a controller connected to port 5003 sends an I_VERSION request.
-
@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.

@masmat This is my mosquitto.log

-
@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?
-
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
-
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.
-
@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...

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
-
Look also in node log, that's the first place to look at
-
@gohan I did, I will post it (but it appears to send normally). But the only things I changed was:
- Rpi configure added: --my-signing=password --my-signing-password=ZZZZZZ
- In the nodes code: #define MY_SIGNING_SIMPLE_PASSWD = "ZZZZZZ"
-
I use also these parameters with the normal signing
--my-signing=software --my-signing-request-signatures --my-signing-weak_security --my-signing-debugof course the debug parameter is there only for debug reasons
-
@masmat check that the version you are using (release or beta) match your use of the simple flags, as they differ at the moment.
-
@anticimex Both Arduino IDE is 2.2 and Rpi is compiled with 2.2 stable.
I'm seeing !TSF:MSG:SIGN FAIL in the serial monitor so something is not compatible... I will try making password >8 characters next (currently 6).I will also add those parameters to see if that makes a difference before reuploading arduino code
-
@masmat if you add the signing debug flag and use the log parser on the homepage it should become clear what the problem is. You can also use the troubleshooting guide in the signing documentation.
-
@anticimex This is what's happening in the gw:
TSF:MSG:READ,36-192-15,s=69,c=0,t=81,pt=1,l=21,sg=0:221
!TSF:MSG:LEN,16!=28
TSF:MSG:READ,75-68-77,s=48,c=1,t=110,pt=1,l=25,sg=1:249
!TSF:MSG:LEN,16!=32The parser didn't really help much: more baffled than before....and I came away from the troubleshooting guide feeling really stupid
-
@masmat looks to me that your gateway is not set up for signing
-
@anticimex I think he didn't use all the parameters for the configure, right?
-
@gohan the simple flags should not need more args, but I don't use a rPi as gw so I honestly am not sure exactly the args to use. The beta documentation has clear instructions for rPi signing, but those are specifically for beta branch and probably don't map exactly to the release yet.
-
@gohan The whole configure-line:
sudo ./configure --my-transport=nrf24 --my-rf24-irq-pin=15 --my-signing=software --my-signing-request-signatures --my-signing-weak_security --my-signing-debug --my-signing=password --my-signing-password=ZZZZZZ --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-user=XXXX --my-mqtt-password=YYYYY --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=18If anyone can tell what's missing or if there's a typo?
-
-
@masmat you have redundant flags. The password option require no other signing flags. Only if you select software as signing backend you need other options (and none of the simple flags)
And remember that if you use software signing and not password signing, you need to personalize the GW and/or node.
-
@anticimex I thought so too, but I'm grasping at straws to get the signing to work.
To clarify, is the following enough for simple signing: --my-signing-debug --my-signing=password --my-signing-password=ZZZZZZAnd the arduino code #define MY_SIGNING_SIMPLE_PASSWD = "ZZZZZZ"
Any difference where it's placed in the code? Anything else to check for?
-
@masmat it needs to be defined prior to the inclusion of mysensors.h. That should be it. (on the arduino node that is).
-
While on the subject: what would be the flags needed for setting the gateway to only use the simple encryption but not the (simple) signing feature?
I looked in the documentation and the node commands aren't mirrored for the gateway. I was hoping for something like:
--MY_SIGNING_SIMPLE_PASSWD=flowerpot77
--MY_ENCRYPTION_SIMPLE_PASSWD=spiderman41
-
It's actually not needed since you can still set signing as optional on gateway
-
@alowhum that feature is still only available for beta and is documented here: https://www.mysensors.org/apidocs-beta/group__SecuritySettingGrpPub.html
EDIT: not yet for rPi
Pull requests are welcome. I don't have time for this at the moment.
-
Right. So is this correct?
NODES (arduino nano)
On all my nodes I will update them to have this code at the top:#define MY_ENCRYPTION_SIMPLE_PASSWD spiderman41 // unfortunately Nano hardware doesn't really have enough memory for signing.
#define MY_RF24_CHANNEL 100 // in EU the default channel 76 overlaps with wifi.
#define MY_RF24_DATARATE RF24_1MBPS // slower datarate makes the network more stable?GATEWAY (Raspberry Pi Zero W)
On my gateway I will use this configure code:--my-security-password=spiderman41
--my-rf24-encryption-enabled
--my-signing-weak_security
--my-rf24-channel=100
--extra-cxxflags="-DMY_RF24_DATARATE=(RF24_1MBPS)"
-
@alowhum you will need to enable weak security as well as that will enable both signing and encryption with signature requirements from all nodes on the gw
-
@Anticimex thanks!
as that will enable both signing and encryption with signature requirements from all nodes on the gw
But I don't want signing? Or do you mean that it will remove that requirement?I only need to set that on the gateway, right?
I've also added a slower datarate, thinking that will also create a more stable connection. I am in a busy urban environment with lots of RF noise. Is that smart?
-
@alowhum I thought you did not want signing: "but not the (simple) signing feature?"
-
Yes, I don't want signing. But what you wrote said that it wil ENABLE signing. Check your sentence. Probably a typo, but I wanted to make sure
-
@alowhum the simple security flag enables signing yes.
-
@alowhum said in
Building a Raspberry Pi Gateway:--my-signing-weak_security
But does the "--my-signing-weak_security" enable signing?
I want to disable signing completely. What flags do I need to use when building a gateway that only uses encryption?
-
@alowhum just don't use any flags mentioning signing, personalize the gw according to the documentation and pick the appropriate encryption flag.
-
@anticimex I've built a new node, DHT11 that sends temp&hum data. I reconfigured Rpi with this:
sudo ./configure --my-transport=nrf24 --my-rf24-irq-pin=15 --my-signing-debug --my-signing=password --my-signing-password=XXXXXX --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-user=YYYY --my-mqtt-password=ZZZZZ --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=18This is what I get in gw syslog:

I will add the code from the node as soon as possible.
-
-
@masmat and this
!SGN:INI:BND FAILMeans the signing backend failed to initialize. So you need to make the password longer.
-
@mfalkvidd Made the password 10 characters. From looks of the logs, it's working now.
I cant believe I skipped the step of making the password longer... Just got too fixated on the password I came up with.
-
@masmat the nonce failures is because the backend never initialized so basically any call to the backend that can fail will fail.
-
I just discovered these USB-to-NRF24 devices. Would it be possible to use that instead of connecting to the GPIO pins?
-
@alowhum not with the existing code. Is there a datasheet that describes how these modules work?
One of the reviews says "have no idea wath software to use with this" so documentation might be hard to come by.
-
Background: I use signing software on some nodes + whitelisting on a node (of course only PI serial is on the whitelist).
With current --development branch (I think 2.3.0alpha) I cannot anymore set my previous personalized flags on gateway RPI3.
In detail, with current master (2.2.0) I can do:
sudo mysgw --set-soft-hmac-key=F618D4[...]848992B sudo mysgw --set-soft-serial-key=26[...]9 sudo mysgw --set-aes-key=EC7[...]CEB4WIth development I did see only the
--get[...]flags and cannot set anymore. Can you confirm?How can I set my previous values for signing?
-
@sineverba I believe this change alters how rPi port handles signing related personalisation: https://github.com/mysensors/MySensors/commit/3c0b2727a56907277d4d04c985fd72b14e4a483c
And, as usual, the documentation is a good place to start

I'm currently compiling the code for connecting the NRF24l01+ directly to the Raspberry PI. Since I'm running the controller (on this case OpenHab) on the same Raspberry PI, would it be recommended the Ethernet or the serial flavor of it?
In the case of ethernet, can I place the own machine IP (127.0.0.1)? This way, if I need to change the IP address of the PI it wouldn't affect the communication between the controller and the MySensors code, right?
--my-gateway=ethernet --my-controller-url-address=127.0.0.1And by the way, for the signing configuration, it is mentioned in the documentation "Update the gateway config file with the generated keys/valeus", what file is that (name, path)?
I should be able to re-use the keys I have defined before, right? So I just go to step 2 (no need to generate new keys).
I'm refering to this link.Thanks,
-
--my-controller-url-address=127.0.0.1 is not needed for ethernet
-
I found that the configuration file is /etc/mysensors.conf but " The first time you start the gateway the configuration file will be created if it does not already exist.", so that's why I wasn't finding it.
Anyway, the file states that:
"Note: The gateway must have been built with signing support to use the options below."What flags should I include to have signing support?
OK, found it: just run ./configure -h and there is a list of options. Leaving it here just for future reference

Thanks for the replies.
I've changed the PI from a PI1 to a PI3 and was able to make it working with signing. Its running smoothly, I guess the GW is chosen :).
I'll now focus on the nodes, specially the SenseBender micros that are 2xAA battery powered and are consuming ~3% bat per day, but that will be for another post...
Thanks!

Hi, is there any way to check the current gateway operating parameters? My purpose is to check the radio channel and power level set before compilation but I would be glad if I could check other configurable parameters. I looked at Makefile.inc and found some flags set, but not the information I was looking for (does it mean that the default values are set)? Debug logs neither provide these informations.
