Migrating to new app? Code updates

[PeteKnight]

From the screen in your screenshot, click the EDIT button, then click on one of the datastreams that you want to be synchronised by the Blynk.syncAll() command.
At the bottom of the pop-up dialogue box click the “+ Advanced Settings” option.
Post a screenshot of what you see - or simply re-read this for the third time, and make the necessary change…

@PeteKnight

Blynk.syncAll() only works for the datastreams you create where you turn on the "Sync with latest server value every time device connects to the cloud` in the datastream’s Advanced options.

I’d recommend using virtual pin datastreams for everything.

Using Virtual Pins to control physical devices

I thought I’d write a guide about how to use virtual pins with app widgets such as buttons, to control physical devices such as relays, LEDs etc… Why use virtual pins anyway? I’d always recommend using virtual pins over physical pins when developing your code. There are a number of reasons, but here are what I consider to be the main ones: Virtual pins are hardware independent. This means that it’s far easier to port your code from one hardware platform to another in future (when you realise…

Why not digital? Or digital can’t be sync, as I need? Kinda silly, that this can’t be sync… Is supposed to be handy in every way, on my opinion. Anyway, thanks. I think it’s all for now.

Can't read Digital & Analog By ESP32S board

@Dmitriy can you explain how the analog and digital datastreams are meant to work for various hardware types? If I choose ESP8266 in the web console I see 5 analog pins available numbered A0-A4. I also see pins numbered 0-14 which I assume represent the digital pins. The ESP8266 has one analog pin, A0. If I choose digital pins for the ESP8266 I see 14 pins, numbered 0-13. The ESP8266 has the following GPIOs: 0, 1, 2, 3, 4, 5, 12, 13, 14 & 15. If I choose ESP32 then I see the same analog pin…

btw, i wanted to say to you -
you forgetting to add to some code, like {} (in this quoted linked messages), and in first message you told, in new code, changed to Edgent.begin();, but its BlynkEdgent.​begin​();. just for your to notice. you helped me, anyway.
its just, that people could copy paste this code and will get errors, so they will open new threads, etc.
