πŸ’¬ Building a Raspberry Pi Gateway



  • 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.

    1. Rpi W, Raspbian wheezy, nRF24-PA, MQTT-gw, Mosquitto and Openhab2 on same board
      Mosquitto-log:
    1521010232: New connection from 127.0.0.1 on port 1883.
    1521010232: New client connected from 127.0.0.1 as mygateway1 (c1, k15, u'xxxx').
    1521010232: Socket error on client mygateway1, disconnecting.

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

    @masmat said in πŸ’¬ 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.


  • Mod

    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?


  • Mod

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


  • Code Contributor

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


  • Code Contributor

    @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



  • @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...


  • Mod

    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-scripts πŸ™‚

    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



  • @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.
    1521141160: New connection from 127.0.0.1 on port 1883.
    ..keeps repeating...

    ...and sudo ./bin/mysgw -d:

    mysgw: Starting gateway...

  • 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.


  • Mod

    @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 😞


  • Mod

    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

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


  • Mod

    @masmat said in πŸ’¬ Building a Raspberry Pi Gateway:

    --my-controller-ip-address=127.0.0.1

    remove that parameter as it is not needed for ethernet


  • Code Contributor

    @masmat I did a test with the following configuration:

    • Raspberry Pi 1 with Raspbian (2017-11-29-raspbian-stretch-lite)

    I'm not using mqtt.
    for debug purposes i use MYSController
    every 10 seconds on the dot. it shows me the version of the gateway.

    @marceloaqno any ideas about that?


  • Mod

    @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,
    Otto


  • Mod

    @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


  • Mod



  • @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.

    Where is mysgw.log?



  • @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?

    Rebooting the pi sometimes helps, sometimes freezes the pi
    seeing nothing strange in the mysensors log what so ever
    running MySensors Version 2.2.0
    and Home Assistant Version 0.64.0
    Anyone can point me in the direction where to troubleshoot this further ?
    its not a high traffic gateway (around 10 sensors connected of which 5 updating every 15 minutes)


  • Mod

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


  • Code Contributor

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


  • Code Contributor

    @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.


  • Code Contributor

  • @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?


  • Mod

    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


  • Code Contributor

    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...

    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
    

  • Mod

    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:

    1. Rpi configure added: --my-signing=password --my-signing-password=ZZZZZZ
    2. In the nodes code: #define MY_SIGNING_SIMPLE_PASSWD = "ZZZZZZ"

  • Mod

    I use also these parameters with the normal signing

    --my-signing=software --my-signing-request-signatures --my-signing-weak_security --my-signing-debug
    

    of course the debug parameter is there only for debug reasons


  • Contest Winner

    @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


  • Contest Winner

    @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!=32

    The parser didn't really help much: more baffled than before....and I came away from the troubleshooting guide feeling really stupid πŸ™‚


  • Contest Winner

    @masmat looks to me that your gateway is not set up for signing


  • Mod

    @anticimex I think he didn't use all the parameters for the configure, right?


  • Contest Winner

    @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=18
    

    If anyone can tell what's missing or if there's a typo?


  • Contest Winner


  • Contest Winner

    @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=ZZZZZZ

    And the arduino code #define MY_SIGNING_SIMPLE_PASSWD = "ZZZZZZ"
    Any difference where it's placed in the code? Anything else to check for?


  • Contest Winner

    @masmat it needs to be defined prior to the inclusion of mysensors.h. That should be it. (on the arduino node that is).


  • Plugin Developer

    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


  • Mod

    It's actually not needed since you can still set signing as optional on gateway


  • Contest Winner

    @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.


  • Plugin Developer

    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)"


  • Contest Winner

    @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


  • Plugin Developer

    @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?


  • Contest Winner

    @alowhum I thought you did not want signing: "but not the (simple) signing feature?"


  • Plugin Developer

    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 πŸ™‚


  • Contest Winner

    @alowhum the simple security flag enables signing yes.


  • Plugin Developer

    @alowhum said in πŸ’¬ 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?


  • Contest Winner

    @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=18

    This is kicking my butt... I cant understand that last part about the nonce 😞
    I will add the code from the node as soon as possible.


  • Mod

    @masmat according to the log parser

    mysgw: !SGN:BND:PWD<8
    

    means the password is too short.


  • Contest Winner

    @masmat and this

    !SGN:INI:BND FAIL
    

    Means 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.


  • Contest Winner

    @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.


  • Hardware Contributor

    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[...]CEB4
    

    WIth development I did see only the --get[...] flags and cannot set anymore. Can you confirm?

    How can I set my previous values for signing?


  • Contest Winner



  • 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=127.0.0.1

    And 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,


  • Mod

    --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...

  • 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.


  • Mod

    What radio are you using?



  • @gohan nrf24, one deployment pa+lna version with external antenna and the other standard with build-in "zig-zag" antenna.


  • Mod

    I always set gw to max power if the radio is shielded

  • @gohan Well, that is not an answer to my question apparently πŸ™‚ I suppose that max power lever is the default setting according to the configure script's help.


  • Mod

    also look for a channel outside the WiFi range



  • Openhab2 on pi3b+ using nrf24 radios and mqtt. I can follow the wiring diagram, but the commands are a bit confusing and seem to jump around randomly. Do I put all the --my-blah-blah together after the ./configure to build a file? Should I do development version? Do the nfr improvements go together with everything else?

    I did some tests on pi3 and I found slow ota too. Tekka has an open issue on github about this.



  • Hey guys,

    I tried to setup my Raspberry running Node-RED and serial gateway but I got stuck halfway. I followed the serial gateway compilation above and got it up and running, however using the serial nodes an Node-RED I could not manage to get them to connect tho the gateway.

    First I tried to connect to /dev/ttyMySensorsGateway which did not work due to permissionsβ€―(owned by root). When checking out /dev/ttyMySensorsGateway I found it links to /dev/pts/1
    which belongs to root and the tty group. But I could not connect to this as the tty group only has write privileges. I think I miss some crucial point connecting those two together so I hope somebody can save the day by pointing me in the right direction.

    Thanks in advance,
    mirodin

    So you run a separate arduino board as a mysensors gateway, connected with serial (USB) to your raspberry pi? Or do you mean that you are using the rpi directly with radio, and then run the rpi variant of the mysensors gateway code?



  • @tbowmo I run the gateway on my Pi directly with the radio is connected to the Pi's GPIOs. Compilation and gateway do just fine I, if only I could convince my Pi to let Node-RED talk to the device πŸ˜„

    EDIT:
    This is my output:

    dietpi@buddy:~ $ ll /dev/ttMySensorsGateway

    wasn't it the problem of the missing permission on the dialup group?



  • Unfortunately adding my nodered user to dialout did not bring the hoped success. I still get premission denied messages after a reboot of my raspberry.

    As my console print above shows the /dev/pts device belongs to tty but adding nodered to tty did not work out eitherβ€―(since the group only has write privileg). I have no idea how to fix this other then chowning the port to nodered but that feels wrong for me after years using linux based systems.

    it is not a solution, but you could switch to ethernet GW and you will avoid all the permissions problems.
