If you're looking for something with an addressable LED matrix in a clock style form factor, the Ulanzi TC001 [0] for ~$50 is worth having a look at.

Doesn't quite have the same aesthetic but inside it's just an ESP32 (flashed via the USB-C port) and there's various mature open source firmware replacements. I use awtrix[1] on mine and it's very easy to tie in HomeAssistant for doorbell notifications and that sort of thing. I did also knock up a Pomodoro app for it.

This looks exactly what I have been looking for to put outside of my home office to keep my family from interrupting me during work meetings. Thanks for sharing it!

The “Live on air!” sign that triggers with Zoom (or Slack) is a very common usecase.

I wonder why it’s not better addressed. It needs to 1. be out of the office, on the door, 2. therefore bluetooth, 3. always on, and 4. it’s simple on/off light!
