A version of this that would be useful for WFH or private offices is an 'on air' device that you could mount outside your office door, which means it's not connected to your computer and could potentially run on a battery for a week+ or run on usb power directly.
People want to come in sometimes to access a closet, but they don't know if your in a meeting, so it would also need to detect if your in a meeting, and the microphone being on or off is not enough because people often mute themselves. Calendar access is also not enough because sometimes you start a meeting without a calendar thingy, and also knowing if your 'on air' with an open door can tell them if they have to be worried if they could be on camera if they walk by the door.
It could be a very simple LED, it just needs a good agent on your desktop. Also a 'yellow light' for an upcoming meeting in a couple minutes (so this is where calendar access is useful) or an orange light for camera & microphone off.
