Angular + ngRx how to Refreshing a component for a new state

Question

I have a doubt about how to update a component, I am making a web app with Angular (lastest version) and I am using ngRx to manage the state.

my web has a Gridview with items where each item is a component (see the image)

Now, I want to update the data inside of ItemComponent, for example the first one item (without add a subcriber in every Item component) but I don't know how to do it.

What is the best way to do this? I want to update any item totally independient between them because if I add a subscribe inside the ItemComponent then I will have to add an conditional to check the component id and exclude it if it's different

I hope I have explained correctly
