With Ysia Patio io you can control a group of the same kind of product (roller shutters, for example). However, you cannot create and control heterogenous group (light + awning for example).
You must first create a group channel. If you have not already done so, please follow the FAQ: How to create a new channel on my Ysia Patio io?
Once your group channel has been created, you need to add the products you want to control with it. To do this, you need to follow the FAQs: How to pair Ysia® Patio io to a new equipement?
To avoid any programming issue, you need to add the new devices one at a time, going through the entire pairing process for each product.
