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

Of course it is not
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?
Even though you weren’t talking to me but I have the same problem
I’m so upset
I need to fix it today or tomorrow
It’s been a while since I’ve been trying to fix this problem
I hope you can help me

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

It’s unlikely that this will work. Why have you chosen to do it this way rather than placing the RTC command here…
as the example in the official documentation suggests?
And why do you have this…
Despite me saying…

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.
Pete.
No it doesn’t work
The strange thing is that the code was working but when I added the void Soilph() and void Clockdispla() parts it stopped working
What are the potential problems?
I will try all the solutions just hope it works well in any way
this is my serial monitor
And what do you mean by powering my board and the peripherals ?
Please copy the output from your serial monitor as text, and paste it between triple backticks, rather than posting screenshots.
Have you tried adding-in your problematic functions one at a time, then commenting out pieces of the problem function until you identify the issue?
How are you powering your devices? Is your power supply up to the task?

It works fine when I delete the void Soilph () parts.
the arduino connected to my laptop
As for the relay, it is connected to a 12V battery, as the water pump needs 12V
So, you seem to have reverted to not fully answering my questions.
Also, you have much more than an Arduino in the equation, yet you seem reluctant to discuss your wiring schematic in detail. That’s fine by me, you can sort out any potential power issues yourself.
Pete.
not like that
I didn’t understand you meant to share the wiring details
also i didn’t understand this part.
my English is not very good
Please take a look this is how the parts are connected
water pump with Relay :
GND >> GND
Vcc>> 3.3v
S >> A5
soil moisture sensor:
GND >> GND
Vcc>> 3.3v
D0>> A0
Ultrasonic sensor:
GND >> GND
Vcc>> 3.3v
Trig >> pin 12
echo>> pin 13
Soil pH sensor:
Vcc>> 3.3 v
GND >> GND
R0 >> pin 2
D1 >> pin 3
RE >> pin 8
DE >> pin 7
ESP8266:
TX >> 10
RX >> 11
GND >> GND
Vcc >> 5 v
CH_PD >> 5 v
Try to change 1000 to 2500 because you already have Wlevel at same time
Thank you
I just did it
But the problem is still the same
