3. Node doesn't receive data from RPI MQTT Gateway

Node doesn't receive data from RPI MQTT Gateway

  • cvdenzen

    I am trying to send data from an MQTT Gateway to a node. I expect the receive() method in my node sketch to be activated when I send an MQTT message to my MQTT gateway.
    The mysgw receives this message, as shown in the logs.
    My sketch in the node (id=156) has a sensor with id 7 of type V_DIMMER.
    I assume the mysgw should forward this message to my node, but no sign of any activity on my node 156.

    Do I have to call wait(time, command, datatype)? In the example sketch for the dimmer, there is no wait() call at all.
    I have implemented the receive() method, but that doesn't seem to get called if I send an MQTT message to my gateway.
    BTW: this gateway is working perfectly with a few other nodes and sensors I have in my MySensors network.

    What am I doing wrong?

    @cvdenzen In case of troubleshooting, try to comment out the maximum of code, only the bare minimum of code should remain active.
    Go back to the original code of the dimmer : https://www.mysensors.org/build/dimmer and test first if this sketch receives the messages.

    No, the bare sketch (with only the necessary modifications, like NEW_DRIVER, NODE_ID etc.) does not receive the message.
    I tried the bare sketch on two different pieces of hardware (an arduino mini pro and an easypirmultisensors2, which also is an 8 MHz avr).
    The sketch:

    /*
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

    Is the mysgw output looking good? The sent message doesn”t include the message type (3). Has anybody tested this with a topic that contains a slash?

  • evb

    @cvdenzen I don't have experience with a Raspberry Pi as MQTT gateway, but your last remark about the slash is maybe a path to debug...

    From the docs for a Arduino MQTT gateway:
    The topic is build like this: MY_MQTT_PUBLISH_TOPIC_PREFIX/FROM-NODE-ID/SENSOR-ID/CMD-TYPE/ACK-FLAG/SUB-TYPE
    Read more about the serial protocol here. An example topic for data received from your gateway could look like this:

    mygateway1-out/2/1/1/0/49

    If you want to send data to your sensors use MY_MQTT_SUBSCRIBE_TOPIC_PREFIX defined in your sketch. Should be looking like this (using default sketch):

    mygateway1-in/2/1/1/0/49

    Can you try to change your mqtt topic build?

    @evb It took some time (have also another home renovation project), but now I have set up a test gateway.
    The mqtt topic with a slash in its name seems to be the problem. I changed the mqtt topic to mysensorsa and now the sketch receives the message. The mqtt gateway outputs:

    I will have a look at the MySensors code and if I cannot find the problem, maybe I will change my mqtt subscription topic.

    @cvdenzen
    I have added a GATEWAY_DEBUG line in core/MyProtocol.cpp at line 122:

    
	for (str = strtok_r(topic + strlen(MY_MQTT_SUBSCRIBE_TOPIC_PREFIX) + 1, "/", &p);
	        str && index < 5;
	        str = strtok_r(NULL, "/", &p), index++
	    ) {
	    GATEWAY_DEBUG(PSTR("GWT:TPS:Index=%d, mqttstr=%s\n"), str);

    My conclusion is that the length of the mqtt subscription topic is the problem. The first call shows that it thinks "rs" is part of the topic beyond the PREFIX. And "rs" gets translated to "0" in the outgoing mqtt message, shifting the real items one position further and dropping the last item.
    Later on I will have a look at the cause of this limitation (or maybe someone else is quicker than I am).
    The output of mysgw, first try is with topic carl/mysensors, second try (that succeeds) is with mqtt topic c/mysensors:

    The problem is clear: the subscription topic that I use contains a wildcard: “+/mysensors”.
    I send my message with prefix “carl/mysensors”.
    The MySensors code assumes the length of the prefix I send is the same as the length of the subscription prefix. But it isn’t because of the wildcard character.
    Is there anybody who likes to change the code to make it work? Or should I try it myself?
    I see two possible solutions:

    1. Parse the message from end to begin and not from begin to end.
    2. Try to match the wildcard character(s) with the sent string.

    I have made some modifications to the code, tested it and it seems to work.
    There is a pull request https://github.com/mysensors/MySensors/pull/1497 but I don't know how this will be handled by the MySensors developers.

    Can anybody give me a link or some information about the development process? A review of my code will be necessary, I am not a C programmer.

    @mfalkvidd Thank you for the link. I followed the instructions, had to download/compile some packages.
    It will take some time for me, I have to solve this error:

     git commit -m "Accept wildcards in mqtt subscription prefix"
cppcheck: Failed to load library configuration file 'std.cfg'. File not found
cppcheck: Failed to load library configuration file 'avr'. File not found
nofile:0:0: information: Failed to load the library avr [failedToLoadCfg]

    Few minutes later, resolved, had to add CFGDIR to make cppcheck:

    sudo make install FILESDIR=/usr/share/cppcheck CFGDIR=/usr/share/cppcheck

    It seems like building MySensors with my edit failed but I don’t understand the error messages.
    The first error: https://ci.mysensors.org/job/MySensors/job/MySensors/job/PR-1497/2/warnings2Result/new/file.702256833/source.9006459693321295180/#1

    @cvdenzen I don't understand the build system, but I have permission to restart builds. Sometimes that helps. I've restarted the build for your PR. Hopefully we'll get a better result this time.

    https://ci.mysensors.org/job/MySensors/job/MySensors/job/PR-1497/3/warnings2Result/new/#1 looks better now
