Can it be done? (Countdown timer that survives wait or sleep)

[Mark Swift]

Hi Guys,

I'm trying to add a simple countdown timer into my sketch. the logic is, if x is true, reset the timer, if it isn't start the timer.

Basically, if rain is detected, reset the timer. If it isn't countdown from 4 hours.

I tried a library that I found but it didn't seem to work with the wait or sleep command (which I expected).

Any ideas?

The number you get from millis() is increased all the time. It wraps around after a few days, but as long as you don't sleep longer than that you should be able to just use the value returned.

Edit: I was wrong. Millis is stoppen when the mcu is sleeping.

[TheoL]

@Mark-Swift When an Arduino sleeps. it sleeps. Meaning that the internal timer sleeps also. Thus millis() continues when woken up. But pauses when sleeping. In my opnion, intelligence like this should be handled by your home automation system.

But it can be done, but not in combination with sleep-mode.

Hi again @mfalkvidd :)

I've not used that before, I don't intend to wait or sleep (depending on if the node's a repeater) longer that a few minutes. Could you give me an example of how I could achieve this?

Basically

 if (lastMoistureValue == 0 ? 1 : 0 == 1 || lastRainValue == 0 ? 1 : 0 == 1)

then reset the timer, else countdown from 4 hours and display the countdown....?

[Mark Swift]

@TheoL I thought as much, I've posted an example of what I'm trying to achieve above, this particular node with only wait (using the MySensors wait) will this make it easier?

[tomkxy]

You can use in addition a real time clock like the DS1307.

[TheoL]

@Mark-Swift I'll look at your code later on. I'm just having a short lunch break. Since you'e using MQTT, things are much easier. You can implement the timing stuff completely in NoeRed. I love MQTT and node red.

[Mark Swift]

@TheoL Thank you!

[AWI]

@Mark-Swift The easiest way to implement a time during sleep (independent from a controller) is count the number of sleep and multiply by the sleep time.

or a more straightforward example:

unsigned long loopTimer ; 

void setup()
{
loopTimer  = 0 ;
}

void loop(){
unsigned long now = millis() ;
// whatever 

// end whatever
loopTimer += now ; 
gw.sleep(sleepTime);
loopTimer += sleepTime ;
}

[Mark Swift]

@AWI That's very interesting. I had considered something like that but couldn't figure out how I'd do it.

Basically, what I'd like to do is have the Arduino light up the neopixel with the remaining hours, i.e. 4 hours, show 4 red LEDS. Not having to reply on a controller for such a simple task seems a bonus. If possible I'll also send the remaining time back to the controller also.

Now I just need to figure out how to apply your timer example to my code, oh dear.

@AWI If you're feeling generous ;-)

[AWI]

@Mark-Swift I'm feeling generous... but the challenge is yours...:laughing: .

If a precision of a few milliseconds is not essential then my idea would be to implement a counter which increments every loop.
If the counter reaches 1 hour (3600 s equals ? times the loopDelay) light up the first, etc.

[Mark Swift]

This post is deleted!

[Mark Swift]

Well, I've been trying and haven't come up with anything that works so far... Crap.

[m26872]

It looks like you don't need to sleep, i.e. the node isn't battery powered. Then it should be very easy by using the basic millis() counter method. http://forum.mysensors.org/topic/630/gateway-sensor-range-advice/12

[Mark Swift]

@m26872 Would you perhaps be able to point me in the right direction with regards my sketch?

Basically, if

if (lastMoistureValue == 0 ? 1 : 0 == 1 || lastRainValue == 0 ? 1 : 0 == 1)

reset timer and set MowerWaiting to true (I guess?)

else

after 1 hour light led 1, after 2 hours light led 2, after 3 hours light led 3, after 4 hours light led 4 (and ideally switch MowerWaiting to false)

Cheers, Mark

[TheoL]

@Mark-Swift Why not make things simple (I love simple things).

if (lastMoistureValue == 0 ? 1 : 0 == 1 || lastMoistureValue == 0 ? 1 : 0 == 1)

Is something that I would code differently. What you are saying is:
if ( inverted value of lastMoistureValue == 1 <-- meaning moisturevalue = 0

or

if ( inverted value of lastMoisterValue == 1 <-- meaning moistureValue = 0

Which basically is a double check for the same. If you'd want to do something when the lastMoistureValue = 0 it would be more logic and simple to say

if ( lastMoistureValue == 0 ) {

But I don't have the time to read this complete thread. To me it always help to write things in pseudo code first. Especially when I have to code a complex algorithm. Like

1. if the lastMoistureValue is off (I presume 0 is off) then do
2. ....

And then I translate the pseudo code to C code.

An algorithm for handling timers could be:

1. If something/sensor value starts a timer.
2. store current time in timerStartVariable
3. if firstTimerElapsed
4. light up led1
5. if secondTimerElapsed
6. light up led2
7. ...... and so on
8. if timer needs reset
9. disable timer mechanism

This gives me lots of insights in what I'd need to code. And there are a lot of different ways you can accomplish this. But for the sake of simplicity I'm not going to use arrays and stuff like that. That is something you can do later on - I'd do immediately, but I wrote my first program 36 years ago on a commodore 64. So I have some experience with software development.

#define firstTimer 36000000 // 60 minutes * 60 seconds * 1000 millis
#define secondTimer 7200000 // 2 times first timer is 2 hours
.... // and so on


bool timerActive =  false; // state for timer active
unsigned long timerStart = 0; // variable for remembering when the timer was triggered
bool timer1Handled = false;
bool timer2Handled = false;
....
....
void loop() {
    if ( timerActive == false && timerNeedsToBeActivated ) { // don't know how you want to trigger it
        timerActive = true;
        timerStart = millis();
        timer1Handled = false;
        timer2Handled = false;
    }
    if ( timerActive == true ) { // check whether a timer has ellapsed
        unsigned long cm = millis();
        if ( timerStart + firstTimer > cm && timer1Handled == false ) {
            timer1Handled = true;
            // light up led1
        }
        if ( timerStart + secondTimer > cm && timer2Handled == false ) {
            timer2Handled = true;
            // light up led1
        }
        if ( timerNeedsToBeStopped ) {
            timerActive = false;
        }
    }
}

Now this might not be the best way to code this algorithm. And I haven't checked if it compiles. But I hope this is what you're looking for. And if so I hope it helped the way I translate an algorithm to a piece of software.

Also there might be some small errors in the code. But I just did some development in Python for a course I'm following. And Python has a different syntax.

@Mark-Swift said:

@TheoL I'll take a look at that and digest it, thank you so much for taking the time to reply.

BTW, spot the typo! It was meant to read:

if (lastMoistureValue == 0 ? 1 : 0 == 1 || lastRainValue == 0 ? 1 : 0 == 1)

[TheoL]

@Mark-Swift My mistake sorry. But it would also make the code more readable by not doing the invert and just compare for the value.

[Mark Swift]

@TheoL I've just tried implementing the code you gave into my sketch, strangely it seems to light all 3 LEDS on the first loop, even though checking the value of 'cm' it's obviously less than timerStarted + TIMERX, any ideas?

Edit: I'm guessing the IF command should be "<" rather than ">" , fixed that. Check the code above for what I'm working on.

The issue I see right now is that if either moisture or rain is detected the mower timer will be reset each loop (that's okay), how can I also reset the countdown timer you created that I've implemented so they're in sync?

@Mark-Swift It's hard to help, sence the sketch is getting large. But From what I'm seeing, you do not store the lastvalues. You allways assing 0 to them

   if (rainValue != lastRainValue) // Check value against saved value
    {
#ifdef MY_DEBUG
      Serial.print("Rain Sensor: ");
      Serial.println(rainValue == 0 ? 1 : 0);
#endif
      send(msg2.set(rainValue == 0 ? 1 : 0)); // Send the inverse
      wait(RADIO_PAUSE);
//      lastRainValue = 0; // For testing can be 0 or 1 or back to rainValue 
        lastRainValue = rainValue; // remember the last value we've read
    }
  }

That would be my first step. If you don't change it, then the sketch will only respond to the sensor's reporting 1.

Also, when the timer is being started you set all led's with a max of 255 for the RED led. If I'm not mistaken, you wanted them to be off. So set the RED value also to 0.

We'll get there step by step.
