Link to Blynk inside a message

How can I send a link to the Blynk app inside a message? (For iphone and Android)

What do you mean exactly ? Give example please.

You can use String Datastream and use regular Blynk.virtualWrite(Vx, "https://123");.
Or you can use widget like ImageGalery and use it via setProperty:

Blynk.setProperty(Vx, "urls", "https://image1.jpg", "https://image2.jpg");
Blynk.setProperty(Vx, "url", 1, "https://image1.jpg");

And you can select the required image via Blynk.virtualWrite(Vx, 1)

Or you use metadata

My system sends Telegram messages. I want to have a link in the message that sends the user to the blynk phone app.

@Flavio_Lemos so you would like to open the app when the user click the link, am I right ?

Yes, John. You are right.

You can try automate app or tasker app.
