And not interact with the Crestron at all....
For what it's worth here, Crestron will interface with Lutron Graffik Eye.
For what you want I think Crestron is overkill, assuming that they will even sell to you.
I would install a Graffik Eye system. I think if they needed load side fuses Lutron would provide or recommend them. I don't know what you are concerned about.
