How often and for how long turn the relay on

[Gunner]

First, please remebler to format your pasted code for proper forum viewing - I have already edited you post above, look back at it to see how it is done.

Secondly, for your issue… This is more a “how to” programming issue then Blynk specific.

You will need to study up on how to use BlynkTimer even more then you do now, as that can do everything you are asking for.

Search this forum for other BlynkTimer delay and Relay based timing solutions. There are there are some good examples already provided.

Here is one example

Virtual pin to control momentary latch relay

Hey Blynkers, I’m a noob wanting to use a Wemos D1 mini + arduino IDE to open my garage door. The issue I’ve got is getting a relay to act like a momentary push switch. In the Blynk app, its fine. Just set the button to ‘push’. The problem is, I also want to be able to open/close the door using IFTTT webhooks. This works, however it latches the pin high = relay latches closed. I was hoping to use some code to get something like webhook pulls virtual pin high - code in Wemos detects pin is high …

Need help with timers

Those are typically the interval timers… they constantly run at set intervals throughout the entire scripts runtime… thus the setup is a logical place to put them. They could technically go anywhere, but then they might reset each time the code reaches them… effectively messing up the timing. Other timers like timeouts can be placed wherever… just be aware that they don’t stop and wait for something to happen, so you have to be cognizant of timeframe when processing multiple timers to do adva…
