How to know the products listed in home?

[gusman126]

I know the following code, to read products of listings, categories, searches etc.

$listing = $this->context->smarty->getTemplateVars('listing');
$products = $listing['products'];

I have used it at home and it does not show me any, I guess the problem is the modules that show the products.
If I use generic template, I can see new, featured products.
If I use template and extra modules I can't see those products,
Is there any way?
