Converting legacy code to Blynk 2.0

It appears perhaps that Blynk 2.0 is not happy with them.

It’s not the Blynk library that decides that’ it’s the board type you select in the Arduino IDE.
I guess you selected “Generic ESP8266” instead of “LOLIN(WEMOS) D1 RS & Mini”

@nikki-m

Eg D3 in my chart says 18, but I understand should be 0.

That’s correct…

@nikki-m

As this project runs in legacy, surely there are enough IO ports in Blynk 2.0??

Blynk doesn’t have any I/O ports, its the board that has the ports.

@nikki-m

I have 4 outputs and 3 inputs on this project

The D1 Mini has sufficient suitable GPIO pins for this, but your original choice of pins probably wasn’t as well informed as it could have been, you should read this…

ESP8266 GPIO pins info, restrictions and features

hi blynkers! the esp8266 mcu is widely used in iot projects. however, most gpio pins on this mcu have special / multiple functionality and are not safe to use in all circumstances. these “features” are still not well documented and not explained in a friendly manner for newbies. i see lots of cases when the “issues” are simply caused by not knowing which pins to use in which case. [esp8266 pin features] here is a basic table for startup. i’ve collected the info from various sources on the i…

Also, your decision to have 54 timers all being called simultaneously every 1000ms isn’t a great idea…

@nikki-m

  timer.setInterval(1000L, myTimerPIR);
  timer.setInterval(1000L, myTimerDoor);
  timer.setInterval(1000L, myTimerDeck);
  timer.setInterval(1000L, myTimerBell);
  timer.setInterval(1000L, myStatusCheck);

You should read the “Staggering Timers” section of this post for more info…

Using BlynkTimer or SimpleTimer

Many users seem to struggle with the basic concepts of using BlynkTimer in their projects, despite the excellent discussions and tutorials that exist on this forum, so I thought I’d write a guide that will hopefully help clarify things. It’s rather long, as it attempts to explain the reasoning behind why and how we use timers, and covers some more advanced subjects, but I’ve tried to organise it in a way that helps people to find answers to specific questions… Why use a timer at all? Let’s say …
