I use motion sensors placed around to detect my MIL movement in the house. I then use Webcore to count these movements up and send a notification twice a day with the sensor count and the last time an event was detected . It’s not quite as important now as before when she didn’t live with us. But we still use it and more specifically when both of us are out of the house.
It also used a virtual button to trigger a report if needed.
Here’s an example of the report we receive twice a day.
"Since Mon, Aug 9 2021 @ 6:30:00 AM CDT. Bathroom detector saw motion 14 times and last motion was Mon, Aug 9 2021 @ 4:04:53 PM CDT. Bedroom detector saw motion 43 times and last motion was Mon, Aug 9 2021 @ 6:27:36 PM CDT. Den detector saw motion 40 times and last motion was Mon, Aug 9 2021 @ 6:26:10 PM CDT. While Don and Sandee were away Kitchen motion detector saw motion 11 times last motion was Mon, Aug 9 2021 @ 11:25:25 AM CDT. Last time counters were reset was Mon, Aug 9 2021 @ 6:30:00 AM CDT.
I used to have more sensors when she lived alone and could more easily see if she hadn’t been moving about the house. Say like not going to kitchen to eat or going to bathroom. That was a sure sign something was probably up.
We were more looking for say a motion event or lack of them (like a zero report, or an event that was a while ago) we could then go to her house and check on her.
I also think there is a few built in (used to be) apps to monitor motion for elderly people. But I don’t remember what they were and I’d have to look when I’m not mobile.
1 we used to use was like a no motion in this amount of time alert. And 1 used to monitor 2 separate motion sensors and alert if 1 tripped but the other didn’t. Like if you went into the bathroom but didn’t come back out to the bedroom (or something like that)
I think your more looking to see if he tries to get up. Just thought I’d share maybe it would help trigger an idea?
