The genius design of Busy Bar makes it a life hacking LED must-have for me
This clever LED display tells everyone when to leave you alone – and despite that sounding mean, I kind of love it
Quick Summary
Busy Bar is a simple desktop gadget with a surprisingly smart idea behind it.
Pairing an LED display with app integrations, it lets you show your availability, silence interruptions and even automate your workday.
Most desk gadgets promise to boost your productivity. Busy Bar takes a different approach by trying to stop everyone else ruining it instead.
The small LED display sits on your desk or office door and clearly shows whether you're available, busy, in a meeting or simply don't want to be disturbed. That's useful enough on its own, but it's the software behind it that makes the idea far more compelling.
Busy Bar integrates with apps including Slack, Microsoft Teams, Zoom and Google Calendar, automatically changing your status as your day unfolds.
Start a meeting and the display updates itself. Finish a call and it switches back without you lifting a finger.
There's even support for Home Assistant, so it can trigger automations around your home or office.
The built-in button can also be customised to launch shortcuts or smart home routines, making it much more than just a digital "Do Not Disturb" sign.
It's one of those products that makes you wonder why nobody thought of it sooner. We've all taped handwritten notes to a door or fired off Slack messages saying "Give me ten minutes", but Busy Bar turns that into something automatic, colourful and surprisingly elegant.

There's even an RGB matrix display for custom animations, countdown timers and notifications, giving it a playful edge alongside the practical features.
At $249 (around £180 / AU$375), it isn't an impulse buy, but it's also not aimed at everyone. If you mostly work from home, juggle meetings all day or simply want fewer interruptions, it's a genuinely clever idea that could save far more time than another AI app ever will.
Sometimes the smartest tech isn't the flashiest but the gadget that actually helps you be left alone.
