Motion Sensor not presenting to RS485 Gateway / TSM:FPAR:NO REPLY



  • Hardware: Arduino nano boards+ RS485 devices with separate 5 volt power supply

    I am trying to set up my 1st Rs485 gateway motion sensor on Home Assistant, per the following tutorial:
    https://www.mysensors.org/build/rs485

    The motion sensor is not presenting itself to the gateway, so I did some digging and found this thread on the subject:

    https://forum.mysensors.org/topic/11048/mqtt-ethernet-gateway-with-wired-rs485-network.

    I have things wired up as per this pic provided in the tutorial

    Although I am not using mqtt, everything seemed to be pertinent but I was still unable to get communication between the sensor and gateway.

    Ha logs show the gateway seems to be happy:

    [mysensors] Connected to Serial<id=0x7f2fd0c2f518, open=True>(port='/dev/ttyUSB0', baudrate=115200, bytesize=8, parity='N', stopbits=1, timeout=0, xonxoff=False, rtscts=False, dsrdtr=False)
    2020-10-05 13:17:05 INFO (MainThread) [mysensors] Connected to <_SelectorSocketTransport fd=25 read=idle write=<idle, bufsize=0>>
    p:Gateway startup complete.
    

    However serial monitor for the motion sensor shows the following:

    * DESCRIPTION
    * The RS485 Gateway prints data received from sensors on the serial link.
    * The gateway accepts input on seral which will be sent out on
    * the RS485 link.
    *
    * Wire connections (OPTIONAL):
    * - Inclusion button should be connected between digital pin 3 and GND
    * - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
    *
    * LEDs (OPTIONAL):
    * - RX (green) - blink fast on radio message received. In inclusion mode will blink fast only on presentation received
    * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
    * - ERR (red) - fast blink on error during transmission error or receive crc error
    *
    * If your Arduino board has additional serial ports
    * you can use to connect the RS485 module.
    * Otherwise, the gateway uses AltSoftSerial to handle two serial
    * links on one Arduino. Use the following pins for RS485 link

    To rule out hardware failure, I followed this tutorial, and all works as expected:

    Transmitter sketch:

    const int ledPin =  13;  // Built-in LED

    void setup() 
    {

    Any ideas about what might be causing the issue?


  • Mod

    @mrhutchinsonmn I haven’t used rs485 myself, but I think it will work better if you use the same speed for MY_RS485_BAUD_RATE on gateway and nodes.



  • @mrhutchinsonmn said in Motion Sensor not presenting to RS485 Gateway / TSM:FPAR:NO REPLY:

    9600

    Good catch.. That was an old version... both are set to 115200 after 9600 did not work



  • @mrhutchinsonmn Might have confused the issue with my reply.. Neither 115200 nor 9600 baud rates resolve the communication issue.


  • Mod

    The sketch uses MY_RS485_HWSERIAL but you say you have wired according to https://forum.mysensors.org/topic/11048/mqtt-ethernet-gateway-with-wired-rs485-network which uses pins 8 and 9?

    Pins 8 and 9 are not the hardware serial pins.



  • @mfalkvidd Ugh!!! Too many versions of the sketch :)... Had to switch between my laptop and pc because of sketch upload issues.... Must have grabbed an old sketch.. I HAD commented hwserial out earlier... Getting communication now but not a valid message, not enough values to unpack errors. I will dig into that tomorrow. Thank you!!!


  • Mod

    @mrhutchinsonmn I would try 9600 again. 115200 leaves very little room for interference and oscillator differences.



  • Thank you for the advice!

    I started over, just to be sure I didn't have anymore mix ups, but still have not been able to get the RS485 motion sensor and RS485 gateway to talk.

    Ideas?



  • @mrhutchinsonmn At RS485, it's obligatory to assign NodeIDs within your sketch.



  • You should move the define for the node ID before you include mysensors.h



  • @rejoe2 In research, some stated it needed to be there if the sensor did not present itself. Followed @electrik advice and it now works. Thank you for your feedback!



  • @electrik Yes... that worked!!! Moved node and child id above mysensors.h

    Thank you!!!!
