It's not clear how i am supposed to connect devices with my onion.
I have some great ideas and want to start off with something simple stuff like connecting my lights so i can turn them on/off with my phone. How can i do that? Do i need something else to connect them? Or do i need to connect them with wires? If so, do i need a new onion for every device/room to make wiring easy ?
Can i connect anything else or are there some limitations ?

You'd need the relay expansion for that:
Relays are basically electrically operated switches that use low-power signals (from the Omega) to control higher voltage circuits, like lamps or home appliances.
The Relay Expansion has two relay modules, you would be able to control two appliances in your home over the internet using the Omega.
The Relay Expansions are also stackable, so you can have as many as you want.

And also this: https://onion.freshdesk.com/support/solutions/articles/6000082229-how-can-i-use-the-relay-expansion-
In terms of controlling our Omegas remotely, well they're still working on getting us the apps and libraries to make that kind of thing easier. In the meantime, if all you've got is the expansion dock, you could start playing around with GPIO? I'm new to this and just having fun with that so far.
