RFM69 with Binary Switch example requires additional code

  • Hi
    I finally managed to try out the MySensors v1.5 library. I mainly was looking for the support of the RFM69 radios because of their better range and low power consumption.
    The serial gateway worked like a charm out of the box. But then I struggled to get the binary switch example working. I mostly got an error 'Radio Init Fail'.
    Looking into the code I also struggled to see where the code says that this should work with an RFM69 radio, like it does in the Serial Gateway code in "MyTransportNRF24 transport(RF24_CE_PIN, RF24_CS_PIN, RF24_PA_LEVEL_GW);"
    So I eventually copied a whole bunch of lines from the Serial Gateway example and now it is working perfectly.

    I may have copied too many lines and perhaps there is a much smarterway of solving this but as a feedback of what I tried and what worked, herewith the code I eventually used in my Binary Switch node:

    • 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.

    MySensor gw(transport, hw /, signer/, RADIO_RX_LED_PIN, RADIO_TX_LED_PIN, RADIO_ERROR_LED_PIN);
    MySensor gw(transport, hw /, signer/);

    Bounce debouncer = Bounce();
    int oldValue=-1;

    // Change to V_LIGHT if you use S_LIGHT in presentation below
    MyMessage msg(CHILD_ID,V_TRIPPED);

    void setup()

    // Setup the button
    // Activate internal pull-up

    // After setting up the button, setup debouncer

    // Register binary input sensor to gw (they will be created as child devices)
    // You can use S_DOOR, S_MOTION or S_LIGHT here depending on your usage.
    // If S_LIGHT is used, remember to update variable type you send in. See "msg" above.
    gw.present(CHILD_ID, S_DOOR);

    // Check if digital input has changed and send in new value
    void loop()
    // Get the update value
    int value = debouncer.read();

    if (value != oldValue) {
    // Send in the new value
    gw.send(msg.set(value==HIGH ? 1 : 0));
    oldValue = value;

    I hope this helps somebody and perhaps somebody wants to advise on how to do this much better.
    Anyhow, Big Thank You to the guys (@KOLAF,@YVEAUX, @HEK and a bunch of others) who made the effort to extend the library to RFM69. Much appreciated.

  • Excellent, it worked
