If the LED on your wireless control doesn't light up when you press its two buttons for 20s, you'll need to reset each product of your Easy Kit individually, before installing them in Home + Control.
To reset a wireless control, follow the instructions in this article.
To reset a wired product (powered by your electrical network), follow the instructions in this article.
Once the products in the pack have been correctly reset, go to the Home + Control app, click on "add a product", and add your products as if they were classic Legrand / Bticino connected products.
