I need a few—probably 3—of an "office busy light" product like this https://amzn.to/4b1vvUZ for a home office setup. But:

1. They all cost like $50 which seems like *way* too much for an LED on a stick
2. That cost seems to mostly pay for software that directly integrates with Microsoft Teams. I have no need for integration with Microsoft Teams and in fact kind of anti-want that.
3. I want to write my own automations and it's not clear if they have an API

Is there a cheap/DIY version of this?
