setProperty in automation Blynk IOT

Need Help With My Project
1

Hi, Im currently deveping a project to control 100 WS812B RGB Led using Blynk IOT. currently, im using free plan and limited to only 50 datastreams. To control all 100 leds individually, Im using a slider and 10 virtual pins.

project principle:
when slider == 1, V0 = 1, V2 = 2, …, V9 = 10
when slider == 2, V0 = 11, V2 =12, …, V9 = 10

So, everytime slider changes value, the onLabels and offLabel of every virtual pin need to change. right now im using for loop to call Blynk.setProperty(V0, “onLabel”, “”); but it is slow updating the on and off labels.
sample codes:

I know that i could do this using eventor setProperty setting on Blynk legacy but i read and search everything in documentation and google but nothing found.

Screenshot Blynk legacy eventor:

In automations, we only can change button state to on and off but not the property. and also i tried to use https api but only can update the mutiple pins value but not multiple pins properties.
the link for the https api documentation is also couldnt help bcs nothing is there.

My question is, is there any work around for me to get the same result as in eventor setProperty(Blynk legacy) in Automation (Blynk IOT)

Are you talking about 100 physical LEDs or 100 LED widgets?

If it’s physical LEDs then how are they connected to your hardware?
If it’s LED widgets then the free plan has a limit of 30 widgets per template, so how are you achieving 100 widgets?

Hi Pete,

Im controlling WS812B RGB Led strip not LED widgets.
Leds are connected in series and im using FastLed library for controlling the led array.

Im not using 100widgets. im using one slider for index, and 10 Button widgets. So if slider value is 1, button widgets should display 11,12,13,14,15,16,17,18,19 and 20. and if slider value is 2, button widgets display 21,22,23,24,25,26,27,28,29 and 30 and so on…

edit:
to clarify, im using 11 widgets to control led arrays

That info should have been in your first post, along with your sketch and screenshots of your app.

Pete.

Hi Pete,

I updated my questions.

thanks

I assume that this should say V9=19 ?

I’ll wait until I see your full sketch before commenting further.

Pete.

Yes. that should say V9 = 20. bad typo. I think you get my point for this project.

Sorry for the delay. This is my first time asking questions. I already pasted my full sketch without the Blynk credentials part.

Thanks

You appear to have deleted the Blynk libraries and who knows what else.
You’d be far better replacing credentials with the word “REDACTED”.

Pete.
