How many times I can use Blynk Timer?

Sometimes I want to start rolling a window in room 1 and while it is rolling start rolling another window.

That sounds like a situation where a timeout timer, probably as part of a lambda function, is a far better solution than having an interval timer that is running all the time.

@Lukas_Holoubek

and it uses Millis functions with while which does this annoying thing once you start rolling one blind untill the loop finishes you cannot do anything else

That’s bad coding. If you did it properly then you wouldn’t need to wait. However, there is no need to use millis comparison in most situations, timeout timers are a much better option in most situations.

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 …
