Problems with Node sensor



  • Hello guys!. I got tutorial "http://www.makeuseof.com/tag/diy-smart-home-sensors-arduino-mysensors-openhab/". But i didn't see humiditysensor in library. Then, i got code from https://www.mysensors.org/build/humidity and uploaded sketch on my sensors node and serial monitor look like this alt text
    and
    alt text
    it's different to what i see in tutorial alt text
    what is "st=bc"?
    Thank you for taking the time to help and sorry because my English is not good.



  • I have the same problem with different nodes. Yesterday only one node hade this problem today i have 2 nodes.
    any commens on this topic?

    i have a ethernet gateway.

    Tms:fpar:fail

    Welcome to the MySensors community @tandobkhcm and @mhko ! I'll handle tandobkhcm's problem first since that's the problem where I have some information.

    https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help has information on how to read the debug output. bc means broadcast.

    find parent (fpar) means the node is searching for a way to reach a parent (usually the gateway but can be a repeater node in a more advanced setup, read https://www.mysensors.org/about/network for more details).

    fpar fail means that the node was unable to find a way to reach a parent.

    Please share information on gateway setup, which radio you are using and share the sketch for the gateway.

    radio fail means that the node is unable to initialize the radio. This is usually due to incorrect wiring.



  • Hi @mfalkvidd !. Thank you for that infomations. I'll read https://ci.mysensors.org/job/Verifiers/job/MySensorsArduino/branch/development/Doxygen_HTML/group__MyTransportgrp.html#details.

    After I convert Mysensors 1.5.x -> 2.0 it's probably working. But i don't see temperature and humidity to display serial monitor

  • Thanks for the time and effort.
    The links did help me, sometime it can be very difficult to find the relevant information for problem solving, so the help i much appreciated.

    it all turn out to be a dodig antenna connector on me GW radio. I am using the nRF24L01+PA+LNA.



  • Guys, i'm having the same problem but with a serial GW..

    Any ideas?
