“Hello Home Action” is the original pre-– 2015 name for what are called “routines” in the SmartThings classic app and are now just folded into “automations” in the new “SmartThings (Samsung Connect)” app.
But since everything that is described in the first part of this thread is literally years old, stuff just doesn’t work the same way now. So you wouldn’t do it that way anymore.
You’ve gotten a couple of good suggestions for currently available methods. You could also do something with webcore.
That said, as someone who does myself depend on a medical monitoring system (I’m quadriparetic) I agree absolutely with the comments that smartthings just isn’t reliable enough for those type of use cases. As the company says themselves in their product usage guidelines:
Data accuracy and consistency from SmartThings sensors, including those provided by SmartThings directly, resold by SmartThings, or supported by SmartThings, is not guaranteed. Therefore, you should not rely on that data for any use that impacts health, safety, security, property or financial interests.
All it would take is one false positive from SmartThings and you would think someone was moving around the house when they might in fact have fallen and be lying on the floor for hours or even days.
We did have one community member working with the VA on a project very similar to yours. You can see those discussion threads by looking on the quick browse lists in the community – created wiki, looking down near the bottom of that page for the “project reports” section and then choosing the list on accessibility.
However, they ended up not using SmartThings for monitoring because of the reliability issues and went with something else. You might track him down and ask for his advice as well.
These days, our use SmartThings for convenience cases like notifying me if the guestroom window is open, rain is expected, and the guest has left the house. It does that way better than anything else in the same price range. But I don’t use it for any critical cases. In my situation, reliability Has to be my top priority as I just don’t have the same “Plan B” options as able-bodied people do.
