The Echo is good, but only if the person is conscious and audible after the fall. And of course within range of the Echo.
The fall detector systems will automatically contact the medical monitoring center with an alert if the person falls, even if they are unconscious.
So different use cases.
This is one of those things we run into with a lot of medical management systems.
Is this a life and death need you really need to meet? Or is this a case of “what cool features can I make this gadget do?”
There are a lot of ways you can use SmartThings to send a text. And that will be all that some people need. But if you have a specific need for fall detection monitoring, you’ll probably go to a different system, just to cover all the bases.
FWIW…
