This second set of serial output doesn’t start from the same point as the first one - i.e. you’ve not just booted-up the device and connected to Blynk.
Can you post a repetition of what you do to create the first serial output, but leaving the button widget in the OFF position before pressing the physical button?
Pete.

But when I start to study your code in detail I see this…
You need to delete these two lines from the top of your code:
then deal with any compilation errors that this throws-up by replacing them with relais1Sate or !relais1Sate as appropriate.
Once you’ve done that, re-test your code and see what results you’re getting. If it’s still the same then repeat the process of posting your revised code and the two new sets of serial outputs.
Pete.

is this disconnected popup normal?
So around 55 wasted posts because you didn’t get rid of these variables!
I’m not sure what the pop up you’re referring to looks like, but you should probably look at the Notification options in the Project Settings.
Pete.
