Can Blynk receive notifications from hardware and let user answer?

I mean for example can hardware send message to Blynk user that:

“Now this and that thing happened, would you like to continue? Yes or No?”

“Notification” seems to do something like that. Blynk.notify(" ++++");

Is there some way to send notification when i want and let me also answer to that somehow?

Yes… with Push Notifications

Not directly… you would have to enter the App and use something like Terminal, Text input, etc… or depending on the required answer, I guess you could setup YES and NO Home Screen Button Widgets that would only do something after said notification.

Thanks. Notification works fine, so I have to go to app and make some options there. Works that way then… it´s ok.
