ZUno , sleep mode and current absorption

Post by Miklux »

Hi all,

I have a little problem with the sleep mode.
I'm working with the 2.1.5 version and I'm working with the dynamic approach.
I'm measuring the current absorbed by the device and I see that it's constantly at 32 mA , even I place the zunoSendDeviceToSleep() command.

Note that I'm using an oscilloscope with a current probe very sensible.

I don't understand how could I put my device in sleep in order to reduce the current consumption...

Here is my code... what's wrong?

Code: Select all

#include <Wire.h>

#define MAP_TO_ZEROCHANNEL 0x80

//MICS
#define MICS_VZ_89TE_ADDR      0x70 //0x70 default I2C address
//registers
#define MICS_VZ_89TE_ADDR_CMD_GETSTATUS  0x0C  // This command is used to read the VZ89 status coded with 6 bytes:
#define MICS_VZ_89TE_DATE_CODE 0x0D

ZUNO_DYNAMIC_CHANNELS(3);
ZUNO_ENABLE(WITH_CC_SENSOR_MULTILEVEL);
ZUNO_SETUP_SLEEPING_MODE(ZUNO_SLEEPING_MODE_FREQUENTLY_AWAKE); 



void setup(){
  delay(1000);
  // DEFINIZIONE DELLA GESTIONE DINAMICA DEI CANALI
  ZUNO_START_CONFIG();
  ZUNO_SET_ZWCHANNEL(MAP_TO_ZEROCHANNEL| 1); // <- this channel will be provided via 1 & 0 channels
  ZUNO_ADD_CHANNEL(ZUNO_SENSOR_MULTILEVEL_CHANNEL_NUMBER, ZUNO_SENSOR_MULTILEVEL_TYPE_CO2_LEVEL, SENSOR_MULTILEVEL_PROPERTIES_COMBINER( SENSOR_MULTILEVEL_SCALE_PERCENTAGE_VALUE, SENSOR_MULTILEVEL_SIZE_TWO_BYTES, SENSOR_MULTILEVEL_PRECISION_ZERO_DECIMALS));
  ZUNO_SET_ZWCHANNEL(2);
  ZUNO_ADD_CHANNEL(ZUNO_SENSOR_MULTILEVEL_CHANNEL_NUMBER, ZUNO_SENSOR_MULTILEVEL_TYPE_CO2_LEVEL, SENSOR_MULTILEVEL_PROPERTIES_COMBINER( SENSOR_MULTILEVEL_SCALE_PERCENTAGE_VALUE, SENSOR_MULTILEVEL_SIZE_TWO_BYTES, SENSOR_MULTILEVEL_PRECISION_ZERO_DECIMALS));
  ZUNO_COMMIT_CONFIG();
  //...  
  Wire.begin();
  Serial.begin(115200);

}

void loop(){
  int i=0;
  int data[7];

  unsigned int CO2=0;
  unsigned int VOC=0;
  float CO2f=0.0;
  float VOCf=0.0;
  float statoS;

/*
  Wire.requestFrom(0x70,7);
  i=0;

  while(Wire.available()){
    data[i++] = Wire.read();
  }
*/

  Wire.beginTransmission((uint8_t)MICS_VZ_89TE_ADDR);
  Wire.write((uint8_t)MICS_VZ_89TE_ADDR_CMD_GETSTATUS); //This send the command to get data
  Wire.write(0x0);
  Wire.write(0x0);
  Wire.write(0x0);
  Wire.write(0x0);
  Wire.write(0x0);
  Wire.endTransmission();
  
  Wire.beginTransmission(0xE1);
  Wire.endTransmission();
  
  Wire.requestFrom((uint8_t)0x70, (byte)7);
  for (i=0; i<7; i++) {
  data[i] = Wire.read();
  }

  //VOC = ((data[0]) - 13)*(1000/229);     // ppb: 0 .. 1000 
  //CO2 = (data[1] - 13)*(1600/229)+400; // ppm: 400 .. 2000ù

  statoS = data[5];
  CO2f = (data[1] - 13) * (1600.0 / 229) + 400; // ppm: 400 .. 2000
  VOCf = (data[0] - 13) * (1000.0/229); // ppb: 0 .. 1000

  //CO2 = (data[1] - 13) * (1600.0 / 229) + 400; // ppm: 400 .. 2000
  //VOC = (data[0] - 13) * (1000.0/229); // ppb: 0 .. 1000
  CO2=(unsigned int) CO2f;
  VOC=(unsigned int) VOCf;
  
  if(VOC<0) VOCf=0;
  if(CO2<400) CO2f=400;

  if(VOC>1000) VOC=1000;
  if(CO2>2000) CO2=2000;
  
  if(VOCf<0.0) VOCf=0.0;
  if(CO2f<400.0) CO2f=400.0;

  if(VOCf>1000.0) VOC=1000.0;
  if(CO2f>2000.0) CO2=2000.0;
  
  Serial.print(CO2f);
  Serial.print(",");
  Serial.println(VOCf);
  Serial.println();


  g_channels_data[0].wParam = CO2;
  zunoSendReport(1);
  
  g_channels_data[1].wParam = VOC;
  
  zunoSendReport(2);
  delay(2000);
  zunoSendDeviceToSleep(); 
}
Thank you in advance for your attention! ;)

Hi,

it should work - I have solar powered sensors, they are working fine in sleep mode.
You are sure that the current is coming from Z-Uno?

The controller (Z-Way or else) show it as sleeping device?

Have you any controller logs checked?

I will take your sketch in next days and check it 1:1 and tell you....

Hi guys, did this ever get resolved? It seems to be related to my question here (https://forum.z-wave.me/viewtopic.php?f=3427&t=33805), so just trying to gather any extra data on the sleep mode functionality.
