There was a Minnesota company called Healthsense (was acquired by GreatCall which was then acquired by BestBuy, not sure if the company/tech exists anymore) that had a similar approach on a broader scale. Their system used a bunch of mundane smart home sensors in the usual configuration (e.g. contact sensors on doors, motion sensors, etc) but also for tracking patterns and habits, like the refrigerator door, toilet seat, bed, etc. The idea being that an abrupt shift in behavior would trigger a notice for a loved one or nurse to check in. I always thought this was a cool idea and it's a shame it didn't take off a bit more.

The question of "intrusion" was always interesting to me because old folks often face going from nothing to assisted living or nursing home which is often quite intrusive, where somewhat ironically adding a bunch of sensors to your home allows you a bit more privacy.

Kind of a tangent, but I like your type of system as an alternative to the emergency pendants. It always struck me as strange to expect old folks at risk of fall to remember to charge and wear a pendant at all times.
