Help adding battery level to switch sketch

[Cliff Karlsson]

I have a sketch witch is used to report when a button is switched:

#include <MySensor.h>
#include <SPI.h>
#include <MyTransportRFM69.h>

#define SKETCH_NAME "BinSwSleepBat"
#define SKETCH_VERSION "1-2"
#define CHILD_ID 0

MyTransportRFM69 transport; 
MySensor gw(transport);

MySensor mys;

MyMessage msg(CHILD_ID, V_TRIPPED); // Change to V_LIGHT if you use S_LIGHT in presentation below
int BATTERY_SENSE_PIN = A0;  // select the input pin for the battery sense point
int sentValue=2;

void setup()  
{    
  mys.begin();  
  
  pinMode(BUTTON_PIN, INPUT);   // Setup the buttons
  digitalWrite(BUTTON_PIN, HIGH);   // Activate internal pull-ups
  
  mys.sendSketchInfo(SKETCH_NAME, SKETCH_VERSION);
  mys.present(CHILD_ID, S_DOOR);
}

void loop()  // Loop will iterate on changes on the BUTTON_PINs
{

  mys.sleep(50);  // Short delay to allow buttons to properly settle 
  
  uint8_t val = digitalRead(BUTTON_PIN);
  if (val != sentValue) {  // If value has changed from last transmission, send the updated value
     mys.send(msg.set(val==HIGH ? 1 : 0));
     sentValue = val;
  }
   
  mys.sleep(BUTTON_PIN-2, CHANGE, 0); // Sleep until something happens with the sensor
}

I want to add the battery level sketch so that it sleep until button is switched as before but also reports battery-level every 120min

@Cliff-Karlsson said:

mys.sleep(BUTTON_PIN-2, CHANGE, 0);

Change to

wakeUpReason = mys.sleep(BUTTON_PIN-2, CHANGE, SLEEP_TIME);

See documentation on wakeUpReason if you only want to send battery value at wakeup.
