Send fake data to FHEM without transmitter



  • Hello.
    I want to use the mysensors way to connect my selfmade sensors to FHEM.
    I don´t have aNRF24 or RFM69. I use cheep 433 RX / TX modules and this will work with my arduino sketch.
    The trabsmitter is an Attiny85 with DHT11 and 433 and the reciver is an Arduino Uno with display.
    This will work, but i want to use a system like FHEM (or if i can not use this because im to stupid so i search another system)

    My transmitter only will send a 5 digit number, SenderID, Temp, Hum...
    Now i want to convert my data to mysensors protokoll for use with FHEM.
    Im new on FHEM so i must have any input device for testing.

    So i use a sketch for my Arduino Nano and try it...but for any sketch i need a Transmitter like NRF24.
    The sketch will oct work without...so i can not send anything :-(

    I read this
    https://www.mysensors.org/download/serial_api_20

    So i was testing with my Arduino Nano and serialprint, and serialprintln.
    I try
    Serial.println("12:1:1:0:0:36.5");
    Serial.println("12;1;1;0;0;36.5");
    .... and other to simulate a temp sensor .
    But it will not work.

    Can anyone help me ?
    Other problem is FHEM. I define a sensor

    define Sensor MYSENSORS /dev/ttyUSB0@115200

    This will show me connected if i put my Arduino into my Pi3.
    But i dont know what is to do then...
    What must i do fist, define MYSENSORS or define MYSENSORS_DEVICE ?.:sob:

    Many thanks for any help

    Probably easier to use the serial gateway as a starting point.

    Present your sensors (in the presentation()-function).. and then just use the send-function. It translates your commands into the serial MySensors protocol.

    Note, you have to download the current development-branch.



  • Hello.
    I want use the serial gateway...but i don´t want to use the NRF24 at this moment.
    I only want to know the data format send via USB.
    So the data format is:

    node-id;child-sensor-id;message-type;ack;sub-type;payload\n

    but i want send this by myself with an arduino sketch.
    I think i can send this data via serialprint ?


  • Admin

    You don't need to activate any radio for the gateway.



  • Ok, thanks.
    In the gateway i can disable radio.
    But i get an error in the log of FHEM

    MYSENSORS: ignoring set-msg from unknown radioId 0, childId 0 for V_LEVEL

    Can i set the radio ID by myself ?


  • Admin

    Like I said earlier, do you have the latest MySensors version from the development branch installed?



  • I delete the library and copy the developer library to the the arduino folder.
    In serial monitor see this

    :-(

    EDIT: I only put something in the code to let write some data.
    There was no example with temperature or somthing simple, so i use the dust example.


  • Admin

    Hmm. Wonder why about this message "ignoring presentation-msg from unknown radioId".

    I know too little about FHEM to answer you unfortunately.



  • The serial output is ok ?

    0;255;3;0;9;MCO:BGN:INIT OK,ID=0,PAR=0,DIS=0,REG=1

    Can i define a ID by myself ?


  • Admin

    No, a gateway always get id=0



  • Ok, the gateway, but i want to simulate an sensor...or is there no way to do this ?


  • Admin



  • Ok, thanks for your help.
    I will stop here now.
