Simple 4 relay irrigation scheduler

strange I doubled check now by copying from my post and it work on my side.

@hagay
now it’s ok for me
thank you

OK. Made some changes to add system disable button.
To disable the system you have to define number of days to disable (a slider on V33) ,
and press the disable button (V32).
If you set V33 to 1 the system will disable until midnight if you set it to 2 the system will disable until tomorrow midnight …
When pressing the disable button all switches are turned off.
The disable date will be presented on V32 button.
Again this is not fully tested (each iteration is several days to test) so please let me know if you find bugs.

enjoy.

good job @hagay
do you plan to include a “self-run” when no wifi signal is detected? (wifi modem router down)

As far as I know (and it seams to be working on my garden) the Blynk RTC will keep time when no wifi connection.
if no wifi you will not be able to change timers but everything that was configured during wifi up time will be maintained.

ok, I’will simulate that kind off issue , just down my local server and see what happens

many thanks
:wink:

Thanks mate. This is a great addition to your project @hagay. I’ve almost finished running my irrigation hoses and have the sprinkler heads in place. Hopefully by the end of next week it should all be done.

Hagay—Thanks again. This new version works great. Solves the issue I was having with using multiple times. I like the efficiency of the code. I really like the way you write the button label with the start time.

I know you said you did not fully test this. I did notice that when I cycle thru the two time cycles the button label will pickup the wrong start time every other start. Not a big deal. This only affects button label. The time cycle is still correct. Manually starting always labels button correctly.

I study your code and I am learning a lot. Thank you

I like the new buttons Blynk added

Button label shows start time

I Like Your GUI!!
Can you post the QR code ?

About the label I think the problem is with the way activetoday checks current time.
There is a guard time of 90 sec that makes activetoday fire twice for every start time.
Solving it will require some changes (RTC time and active today calls are not sync since RTC may get some time aliments from the web).

I am currently making some big changes to the code to make number of switches and timers configurable using defines.
Not sure if I post the new code here or maybe open a new project (since it is no longer 4 relay and not so simple).

In any case the fix will be in the new code.

This is what I use to control my system. LinkNode R4. It is about $10. Uses ESP 8266 chip. I flash it with Node MCU to blow out the original “junk” programming. I adapted Hagay’s program to work with this device. It uses different GPIO and different LED settings

what do you mean ?
do you need to program a full week or a paticular week in the year ?

1 Like

I mean choose days of week
such as choose a Sun, Tue, Thu and Sat Timer On Reray But Mon, Wed and Fri Timer not work.

I need add choose days of week to my code

you have to use isWeekdaySelected function

@hagay I need add a isWeekdaySelected function to save a value “Weekday” to array type.
such as

  for (int i = 1; i <= 7; i++) {
    if (t.isWeekdaySelected(i)) {
      Serial.println(String("Day ") + i + " is selected");
      weekdays[switch_no][time_no][i] = true;
    }
    else {
      weekdays[switch_no][time_no][i] = false;
    }
    
  }

It seems correct
