converting from Arduino to Z-UNO simple code help needed

Hello from a frustrated Z-UNO user.

I have a simple Switch and Relay example from My Sensors site that will not compile in Z-UNO.

Can anyone please help in converting this from Arduino to Z-UNO, apart from deleting the Radio, I'm lost concerning libraries required etc.

Code: Select all

 * 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.

 * Example sketch for a "light switch" where you can control light or something

 * This node also works as a repeader for other nodes

// Enable debug prints to serial monitor
#define MY_DEBUG 

// Enable and select radio type attached
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69

// Enabled repeater feature for this node

#include <SPI.h>
#include <MySensors.h>
#include <Bounce2.h>

#define RELAY_PIN  4  // Arduino Digital I/O pin number for relay 
#define BUTTON_PIN  3  // Arduino Digital I/O pin number for button 
#define CHILD_ID 1   // Id of the sensor child
#define RELAY_ON 1
#define RELAY_OFF 0

Bounce debouncer = Bounce(); 
int oldValue=0;
bool state;

MyMessage msg(CHILD_ID,V_LIGHT);

void setup()  
  // Setup the button
  // Activate internal pull-up
  // After setting up the button, setup debouncer

  // Make sure relays are off when starting up
  digitalWrite(RELAY_PIN, RELAY_OFF);
  // Then set relay pins in output mode
  pinMode(RELAY_PIN, OUTPUT);   
  // Set relay to last known state (using eeprom storage) 
  state = loadState(CHILD_ID);
  digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);

void presentation()  {
  // Send the sketch version information to the gateway and Controller
  sendSketchInfo("Relay & Button", "1.0");

  // Register all sensors to gw (they will be created as child devices)
  present(CHILD_ID, S_LIGHT);

*  Example on how to asynchronously check for new messages from gw
void loop() 
  // Get the update value
  int value =;
  if (value != oldValue && value==0) {
      send(msg.set(state?false:true), true); // Send new state and request ack back
  oldValue = value;
void receive(const MyMessage &message) {
  // We only expect one type of message from controller. But we better check anyway.
  if (message.isAck()) {
     Serial.println("This is an ack from gateway");

  if (message.type == V_LIGHT) {
     // Change relay state
     state = message.getBool();
     digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);
     // Store state in eeprom
     saveState(CHILD_ID, state);
     // Write some debug info
     Serial.print("Incoming change for sensor:");
     Serial.print(", New status: ");

MySensors.h and Bounce2.h are missing, so it is impossible to tell you more. They will also certainly require some .cpp files with same name

if you only want to have a switch / relay working, why not using directly the examples from Z-Uno? You will need to setup the Z-Uno specific functions anyhow...
