Can I have multiple sleep/interrupt events in the one sketch?

[gadgetman]

I have a prototype battery relay node working, where using smart sleep I am able to turn on a relay (currently just a connected LED) and off from the controller, with a lag in actuation equal to the smart sleep duration.

What I would now like to do is to introduce a secondary function where the node is able to turn the relay off after a preset period if no off command is received from the controller. Is this possible by introducing another sleep timer? If so how could I do this (as opposed to having a controller rule send the off command).

Here's my quick and dirty test sketch - hacked from the relay node example.

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable and select radio type attached
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69
#define MY_RF24_PA_LEVEL RF24_PA_LOW

// Enable repeater functionality for this node
// #define MY_REPEATER_FEATURE

#include <MySensors.h>
#define MY_SMART_SLEEP_WAIT_DURATION_MS 1000


//#define RELAY_1  3  // Arduino Digital I/O pin number for first relay (second on pin+1 etc)
#define LEDpin 5

//#define NUMBER_OF_RELAYS 1 // Total number of attached relays
//#define RELAY_ON 1  // GPIO value to write to turn on attached relay
#define LED_ON 1

//#define RELAY_OFF 0 // GPIO value to write to turn off attached relay
#define LED_OFF 0

#define VMIN 1.9 // Battery monitor lower level. Vmin_radio=1.9V
#define VMAX 3.0 // " " " high level. Vmin<Vmax<=3.44
int BATTERY_SENSE_PIN = A1;  // select the input pin for the battery sense point
int oldBatteryPcnt = 0;

// Sleep time between sensor updates (in milliseconds)
static const uint64_t UPDATE_INTERVAL = 60000;

#define child 1

void before()
{
    //for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
    // Then set relay pins in output mode
    pinMode(LEDpin, OUTPUT);
    // Set relay to last known state (using eeprom storage)
    digitalWrite(LEDpin, loadState(LEDpin)?LED_ON:LED_OFF);
  }
//}


void setup()
{
   analogReference(INTERNAL);     // use the 1.1 V internal reference for battery level measuring

}


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

     //  for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
     // Register all sensors to gw (they will be created as child devices)
     present(child, S_BINARY);
  }
//}

void loop()
{
// get the battery Voltage
    int sensorValue = analogRead(BATTERY_SENSE_PIN);
#ifdef MY_DEBUG
    Serial.println(sensorValue);
#endif

    // 1M, 470K divider across battery and using internal ADC ref of 1.1V
    // Sense point is bypassed with 0.1 uF cap to reduce noise at that point
    // ((1e6+470e3)/470e3)*1.1 = Vmax = 3.44 Volts
    // 3.44/1023 = Volts per bit = 0.003363075


    float batteryV  = sensorValue * 0.003347095;
    int batteryPcnt = static_cast<int>(((batteryV-VMIN)/(VMAX-VMIN))*100); 

#ifdef MY_DEBUG

    Serial.print("Battery Voltage: ");
    Serial.print(batteryV);
    Serial.println(" V");

    Serial.print("Battery percent: ");
    Serial.print(batteryPcnt);
    Serial.println(" %");
#endif

    if (oldBatteryPcnt != batteryPcnt) {
        // Power up radio after sleep
        sendBatteryLevel(batteryPcnt);
        oldBatteryPcnt = batteryPcnt;
    }

  // Sleep for a while to save energy (using martsleep)
smartSleep(UPDATE_INTERVAL); 
  }

void receive(const MyMessage &message)
{
  // We only expect one type of message from controller. But we better check anyway.
  if (message.type==V_STATUS) {
    // Change relay state
    digitalWrite(LEDpin, message.getBool()?LED_ON:LED_OFF);
    // Store state in eeprom
    saveState(LEDpin, message.getBool());
    // Write some debug info
    Serial.print("Incoming change for sensor:");
    Serial.print(message.sensor);
    Serial.print(", New status: ");
    Serial.println(message.getBool());
  }
}

you could count how many times you have ran the loop, if your turn off time is a multiple of sleeptime, when you receive a switch on command you just reset the counter.

@gohan Lol you're absolutely right! I should have thought of that earlier - thanks!
