The only thing that conflicts with the setting is that channellers don't need a machine to sense energy across the world, they can do it naturally just by practicing. However, you can still have a machine that does that, but instead just have it be made for convenience instead. Kinda like a washing machine, it's not made to do something that they can't do, but made to do it more efficiently

Yeah that definitely works. Or maybe the machines somehow improve a person's natural sensing ability? Either one works for me.
