Full sketch needed.

Pete.

[shmukh]

I’ve made thousands of attempts
It turns out that the code works fine when I put it alone, but the problem starts when you put all the loops together in one code.
I am wondering if there is a specific number of episodes allowed or something

[Blynk_Coeur]

Post your full sketch, else we can’t help you

[John93]

@shmukh

timer.setInterval(10L, Wlevel);

You are calling the wlevel() function 100 times per second, increase the time to 1000L for example.

also, I’d suggest using a flags to limit event logging, otherwise you will exceed the daily limit quickly ( the daily limit is 100 events per device per day ).

[PeteKnight]

@shmukh

if (cm == 10)

This test for the water level isn’t very sensible. It requires the water level to be EXACTLY 10cm, not 10.00001 or 9.9999999 but EXACTLY 10.
In reality you could easily miss taking a reading which returns exactly 10, so it’s better to make this <=10

As @John93 said, you also need to include a flag variable which sends just one event/alert for each low water level situation, and to reset this flag when the water level is significantly greater than 10 (so that you don’t get false resets of the water level status when the readings are fluctuating around the 10cm level).

More info here…

Events, Notifications and the use of "Flag" variables

@Dmitriy I’ve been doing a bit more testing on events and notifications and discovered an issue. If you set-up an event, but don’t enable notifications for that event, then in C++ you can do this: Blynk.logEvent("over_temperature_alert", String("Hello World")); and it works fine, the custom description (“Hello World”) appears below the event name in the timeline… [image] But if you use the HTTPS API to do the same thing… blynk.cloud/external/api/logEvent?token=REDACTED&code=over_temperatur…

Also, this…

@shmukh

WidgetRTC rtc;

@shmukh

rtc.begin();
  
  setSyncInterval(10 * 60);

Is the legacy way of getting the time from the Blynk server. You should read the official documentation on the correct IoT method.

Pete.

Where can I read it ?

Click the “Docs” link at the top of this page, and type “RTC” into the search box.

I read the article about RTC but I still don’t understand
In which loop should I put

  Blynk.sendInternal("rtc", "sync");

And do I need to include any libraries?

@shmukh I’ve moved your latest post into this topic. Please don’t spam the forum by posting the same thing in multiple places, especially when the topic is about a Legacy issue not a Blynk IoT issue.

You’d be far better spending your time re-reading what has already been posted in this topic, as you haven’t taken on board most of the guidance that you’ve been given.
You’re not likely to get any further assistance until you’ve done that.

Pete.

[shmukh]

Thank you
But I’m looking for related topics
I also took all instructions into consideration
If there is an error, please guide me
Thanks for everything

[PeteKnight]

You haven’t added flag variables to the logEvent commands to prevent multiple event logging and you haven’t removed the legacy RTC code.

If you’d bothered to re-read the posts in this topic and compare the advice you’ve been given to the changes you’ve made then you would have realised this - but clearly you haven’t taken that piece of advice onboard either.

@shmukh

I’m looking for related topics

Maybe that’s your problem. More time spent looking at the advice given in this topic would be a better approach.

Pete.

[shmukh]

Can you take a look at this please ?
I’ve never used this RTC and flag variables before so I’m not sure if this is true or not

@shmukh

Blynk.begin(auth, wifi, ssid, pass);
   Blynk.sendInternal("rtc", "sync");

It’s unlikely that this will work. Why have you chosen to do it this way rather than placing the RTC command here…

@shmukh

BLYNK_CONNECTED()
{
  Blynk.syncVirtual(V0);  
  }

as the example in the official documentation suggests?

And why do you have this…

@shmukh

#include <WidgetRTC.h>

Despite me saying…

@PeteKnight

Also, this…

@shmukh

WidgetRTC rtc;

@shmukh

> rtc.begin();
  
  setSyncInterval(10 * 60);

Is the legacy way of getting the time from the Blynk server. You should read the official documentation on the correct IoT method.

What about the flag variables please

It’s difficult to follow the code, because of the way that your if statements aren’t indented properly, but it looks okay.

Does it work?

If not, then you need to focus on what you’re seeing in your serial monitor, and how you are powering your board and the peripherals.
