Highlights

• A tray icon with an on/off menu per light, and a control panel with power, brightness, color temperature, and hue and saturation for color lights.
• Lights are found automatically via Bonjour/mDNS, through Avahi when it's running (reliable even with lights on Wi-Fi). If multicast is blocked, pass -host with the lights' addresses.
• The app runs as a single instance: launching it again brings up the panel.
• On GNOME, the tray icon needs the AppIndicator extension. Without a tray, Bulp runs as just the panel window.

On macOS and Windows, use Elgato's official Control Center app (the bulp CLI works on macOS too).

Bulp is an unofficial app, not affiliated with or endorsed by Elgato or Corsair.
