[SOLVED] Spike and lock up problem

  • Today I noticed a problem that I have been experiencing lately and thought I had filtered it out. But it seems the problem may be somewhere else.

    I noticed that the mycontroller web page was not responding and nor was ssh. When I checked the pi I noticed that the led on the ssd (connected via usb to pi) was flashing at fast regular intervals. This was not normal and so I rebooted via power off, wait, power on.

    When it reboots all is well, but here I now see some errant data casuing a spike in the graph like this......


    I have in place on the node the following code so that errant data from the sensor should not pass

     if (pressure != lastPressure){
        if (lastPressure - pressure <= 5) 
            send(pressureMsg.set(pressure, 2),true);
            lastPressure = pressure;

    But on this occasion I had 2 spikes within a 1.5hour wondow, both dropping to 23.9mb and then zooming back up to 1024 (figures from memory). If it were the sensor giving a bad value the above code should filter it out and not send it.
    So how can this be happening? Is the spike data being generated inside the pi? How can I track this issue down further?

  • @skywatch I do not think this issue with MyController.
    your spikes happened 23.90 - 22.48 = 1.42 which is less than 5. So I guess you sketch passes this data.

  • @jkandasa No - that is incorrect.

    MyController graphs on the sensor pages do not auto algin margins with the data and crop it off at the axis. Did you notice the 00.00 in there? Would atmospheric pressue be 24 hpa? I think we'd all be dead!

    The fake drop showing is from 1023.90 to 22.48 i.e. > 5.

    I have had lots more over night.


    Temperature from the node is unaffected and is from the same BMP180 sensor.
    Because of the software filter I can't see this being a sensor problem.
    I will be moving from BMP180 to BME280 soon, but I have similar problem with other nodes using HTU21 and DHT22 as well.

  • @skywatch

    Would atmospheric pressue be 24 hpa? I think we'd all be dead!

    LOL 😂

    I hope this problem from the node [or] from the serial driver, can enable debug log [OR] resources logs, to check the received data?

  • @jkandasa Here's a quick update....

    Now I am running with a 5V 16MHz pro mini with direct serial connection to the pi at 115200 baud.

    I have replaced the pressure sensor and pro-mini it was attached to with a new pro -mini and a BME280. This OFC means a completely new sketch straight off of the mysensors web site (so crossing fingers). Just changed to my node id and rf channel. I powered off of the laptop usb to hope it would get the best power possible.

    I still get the spikes/plunges in data.

    Waiting now for a ttl->usb board from China for the GW and wondering if a promicro wouldn't do the job (or maybe a uno via usb)?

  • @skywatch Well I am totally puzzled by this now.

    Having done everything in my last post (replacing sensor + replacing all GW and NODE HW) I even added the following to the sketch...

    if (pressure >= 870 && pressure <= 1085){
          Serial.println("BME280 - Sending the new pressure to the gateway.");
          send(pressureMsg.set(pressure, 2),true);
          lastPressure = pressure; 

    I still get spikes. I'm baffled!


  • @skywatch I too confused now 😞
    I will add a new option to store raw logs in a separate file. So it will give clarity of this issue.


  • @skywatch I have included debugging raw message option, download SNAPSHOT version and enable debug raw message.

    enable raw message debugging in mycontroller/conf/logback.xml, by default this logger will be in INFO mode. change it to level="DEBUG"

      <logger name="RAW_MESSAGE_LOGGER" level="DEBUG" additivity="false">
        <appender-ref ref="GATEWAY_RAW_MESSAGE_APPENDER" />

    You will get debug logs on mycontroller/logs/raw_message_gw_*.log.

    Please note: From this build, I have enabled google analytics.
    you can see the following agreement on the log file.

    ****************************************** Data Processing Agreement *******************************************
    By using this software you agree that the following non-PII (non personally identifiable information data       
    will be collected, processed and used by MyController.org for the purpose of improving quality of this software.

    by setting 'mcc.collect.anonymous.data=false' and **restart** this server and **logout and login** in the UI.

    If you do not like you can disable it by setting mcc.collect.anonymous.data=false in mycontroller.properties file.

  • @jkandasa

    Thank you! - I will try and do this tomorrow or at the weekend.

    Interestingly I got a negative reading on a dust sensor(!)! - Not sure how to properly interpret that one - Hehehe..... 😉

  • I had some time today and took another look at this.

    With 2 windows open, one showing the graph and one showing status>resource logs I was able to see the odd behaviour.

    In resource logs I see the pressure data correctly being recieved. But the graph does not reflect the data. E.G. We have a big storm for last few days and today I see pressure of 1007.xx being shown in status>resource logs in three consecutive readings each a minute apart. But on graph I am seeing levels of 500 approx. This then morphed into 755 as the cardinal open probably interpolates this using time and values in database (guessing).

    I will see how it goes for a few hours before doing anything else, might be interesting!

  • @skywatch IT didn't go well so I downloaded the snapshot as suggested and changed the conf file for DEBUG.

    I am seeing this...

    But not seeing any extra log file created? Maybe this in the server log is a clue?

  • @skywatch In your log file, this part is missing!


    Better you can copy the whole file and enable gateway "DEBUG" log

  • @jkandasa Thank you!

    It is strange as it is in the zip file and everything was copied across, I cannot imagine how that happened - But all logging well now!

  • @jkandasa

    You will be happy to know that this issue is now SOLVED! 🙂

    Since installing the latest SNAPSHOT 1.4.0, all the problems associated with this have gone away. It has all magically gone back to normal.

    So no more spikes, dropouts, ghost nodes, or lockups. I am very hopeful again now! 😉


    🙂 🙂 🙂
