Can anyone help with an item List of things I would need in order to set up an essay network with my hedgehog4

Hey guys, I currently have a hedgehog4. And I am trying to set up a SACN network. And start running fixtures from my board through ethernet. Thing is I’m completely new to it and not sure what type of products I would need in order to accomplish a task.

I have some idea of what I would need to use. Like a network switcher. And even heard about something called a node that I guess I plug my DMX cables from fixture.

Anyways, not sure if anyone would be willing to send me a basic item list to accomplish the task.
I don’t necessarily need specific brands, but at least some basic item names so I know what to start looking for. If you do have a brand that you recommend, I would appreciate that as well.

This is for a pretty big church used to be an old supermarket.

Not sure if this is the right thread, forgive me if it isn’t.
