  • Z-Way doc https://z-wave.me/essentials

  • Z-Way JS engine GitHub https://github.com/Z-Wave-Me/home-automation/

Z-Way workshop materials



  • Making rules: Settings -> Apps -> Local -> IfThen -> Add

  • Turning on/off a device /ZWaveAPI/Run/devices[NNN].SwitchBinary.Set(0 or 1)

  • Reading switch value /ZWaveAPI/Run/devices[NNN].SwitchBinary.data.level.value

  • Reading sensor value /ZWaveAPI/Run/devices[NNN].SensorBinary.data[12].level.value

  • Using JS API /JS/Run/var v = 1; setInterval(function() { zway.devices[NNN].SwitchBinary.Set(v); v = 1-v;}, 2000);

Z-Uno settings


Make sure to configure in Arduino IDE:

  • File -> Preferences -> Add package source URL http://z-uno.z-wave.me/files/z-uno/package_z-wave.me_index.json

  • Tools -> Board -> Board Manager -> Z-Uno 2.1.5

  • Tools -> Board -> Z-Uno

  • Tools -> Programmer -> Z-Uno

  • Tools -> Port -> /dev/ttyACM0 or /dev/ttyACM1

  • Tools -> Frequency EU/RU (depending on your controller)

  • Tools -> Security none or S0 or S2 - up to you

You might also need to add your user to *dialout* group to have permissions for /dev/ttyACM*

Z-Uno workshop materials


Sketch for Simple Switch: 

 ZUNO_SETUP_CHANNELS(ZUNO_SWITCH_BINARY(state, 0));

 

 byte state = 0;

 

 void setup() {

   pinMode(13, OUTPUT);

 }

 

 void loop() {

   digitalWrite(13, state ? HIGH : LOW);

 }

Sketch in getter/setter style: 


 ZUNO_SETUP_CHANNELS(

   ZUNO_SWITCH_BINARY(getter, setter),

   ZUNO_SENSOR_BINARY_DOOR_WINDOW(doorGetter)

 );

 

 byte state = 0;

 byte door = 0, lastDoor = 0xff;

 

 void setup() {

   pinMode(13, OUTPUT);

   pinMode(18, INPUT);

 }

 

 void loop() {

   digitalWrite(13, state ? HIGH : LOW);

   

   door = digitalRead(18) == LOW ? 0xff : 0;

   if (door != lastDoor) zunoSendReport(2); // push update of channel 2

   lastDoor = door;

 }

 

 void setter(byte val) {

   state = val;

 }

 

 byte getter() {

   return state;

 }

 

 byte doorGetter() {

   return door;

 }
