tengo un proyecto de sensores en line con un usuario y un solo Token como puedo adicionar mas usuarios ??
You could log them in to the Blynk app with your account. But, this would mean that they could make changes to the app.
The other way is to share the app. This costs a one-off non-refundable charge of 1000 units of energy. Shared users then get the same screens and data in the app, but without the ability to stop the app and edit the widgets. If you stop that project on your phone then it will be unavailable to the shared users.
