Shelly products are increasingly present in Portuguese homes and therefore, the need for content in Portuguese is starting to arise.
In a very easy way, people use Shelly products to make their homes smart. That is, controlling lighting, roller shutters, sockets among others via app or voice commands (if you have a virtual assistant / smart speaker).

But what is each Shelly for? 
There is a huge range and each one has its specificities. 

One of the biggest questions beginners in smart homes have is: Shelly vs Sonoff vs Tuya/SmartLife?
These are the 3 most used applications on the market and using devices from one does not prevent the use of the others.

Today we are going to talk and try to clarify everything about Shelly products.
Further on, you will be able to understand where you can use each one and what the advantages/disadvantages of each are, as well as some suggestions on which one to use in each case.

If any topic/idea is not mentioned/addressed, leave it in the comments and we will try to complete this article as much as possible so that it is as complete and explanatory as possible.
