lume

Your key light, your rim light and the lamp behind the monitor, on one command line. No cloud, no vendor app, no account — lume talks to the lamps directly, over your own network.

the whole studio, one command
$ lume studio on

$ lume key on --brightness 80 --kelvin 4500

2900 K is candle-warm, 7000 K is overcast daylight — the range an Elgato Key Light can actually reach. The dot is drawn from the same black-body approximation the CLI uses for its own output.

Profiles, not devices

A profile names one lamp or several, and every verb takes a profile. Controlling a single light and controlling a whole studio are the same shape of command, which means there is only one thing to learn.

$ lume key on --brightness 80 --kelvin 4500
$ lume studio on     # key, rim and the accent light, each at its stored values
$ lume all off

A profile can also remember what each lamp should be doing. That turns a lighting setup you spent an evening dialling in into one command — and into one Stream Deck button.

Guide Install it, point it at your lamps, and learn the one idea the command line is built on. Backends What each kind of lamp can do, and what it takes to get access to it. Protocol Notes on both devices, written up so the next person does not have to repeat the work.
