Found out recently that the Philips Hue Bridge has a RESTful API so naturally I needed to write a CLI to control my lights.
I've only just started working on this so I'll update the README with installation instructions and all that soon.
lights on [all] [<light name/id>...]
off [all] [<light name/id>...]
toggle [all] [<light name/id>...]
show [lights] [groups] [scenes]
