Hi @Guillermogotter,
Welcome to the Roku Community!
I get that you encountered an error message on your Roku Smart Home app when trying to set up your Roku doorbell in Argentina. I am more than willing to assist you with this.
This is just a reminder that Roku is a US-based company. This means that if you buy a Roku doorbell in the US, you won't be able to install it or use it outside of the US. This might be the reason why you encountered an error on your Roku Smart Home application.
Thank you for your understanding and cooperation.
Regards,
Riamie
