Control one particle with another

I’m currently undertaking a project at uni and am just wondering the best way to go about it.

Put simply, I want to have two sets of led lights. When one turns on I want the other to turn on as well. They will be in different locations and as such not able to connect to the same network.

From what i’ve read the Photon seems to have the potential to accomplish this but please tell me if i’m completely wrong.

I am new to this so any advice at all would be greatly appreciated. Apologies if this has already been raised in another post.

Thanks in advance

Have a look:
