> The Sengled Smart Health Monitoring Light is a dual Wi-Fi / Bluetooth bulb with built-in health monitoring using radar technology. It’s designed to track your sleep and certain biometric measurements, such as heart rate and body temperature, as well as other vital signs. The bulb can work alone, or multiple bulbs connected via a Bluetooth mesh network work together to create a virtual map that can help detect human behavior.

Who is actually asking for this? It can't be for consumers just wanting to use the internet right? I don't get it.

It's most probably meant for opportunistic sensing in industrial environments, where it might become quite useful. It's not something you're going to use at home.

The only real practical example is fall detection, what's the real purpose of this?

I worked briefly for a company working on WiFi sensing, and besides fall detection, nobody could give a compelling use case.

When pressed to come up with a motivating vision, the big idea was lights turning on automatically when you enter a room.

I guess? Like a lot of R&D, it seemed a solution in search of a problem.
