How to build a “man down” flow?

[FKey]

I want to create a “man down” detection.
Thought it would be simple:

When time is 09:00
AND zone has been inactive for more than 4 hours
Sent a message

But I cannot find any “zone activity” related things in the logic cards, nor in the AND cards of zone activity.

Probably thinking the wrong way?
Any ideas?

I could turn it around, but that could lead to missed alarms or late alarms, because it only triggers once.

When zo’n is inactive for more than 4 hours
AND time is between 08:00 and 10:00

The “when time is 09:00” card only triggers once per day, so is that any better?

Also, don’t trust Homey if this is meant for potentially critical situations.

You could create a flow activated by the zone state that sets a timer going (I use the Chronograph app) when inactive and clears it when active. At 9am you could fire something if the timer has been running for more than four hours.

Or you could set a variable to true if the zone has been inactive for four hours and unset it if the zone is activated, then test the variable in your 9am routine.

True, but for for my situation that would work

Agreed, it’s backup (better than using WhatsApp)

I want to “keep an eye” on my mother who is living alone. But cameras are to much (and still require checks)

I would like to be alerted when my mother did not leave (motion in hallway) her bedroom in the morning.
Normally she is up way before 09:00. So if at 09:00 no motion was detected for hours in the hallway. I want to get an alert.

Same for the evening: at 23:00 more than 2 hours no motion would mean she did not make it to the bedroom

If she would go to bed early, the “zone inactive for 9 hours” could trigger before the set time and not result in a trigger

Using “zone inactive for 2 hours” would trigger unwanted if she gets up early

Well, definitely overlooked that app!
Thanks @Peter_Kawa

I understand the reason why you would want this, I used a similar system for my mother. But it was a dedicated system that included fallbacks to an internal SIM card for when the internet connection was down (which didn’t happen often, but still).

If she would go to bed early, the “zone inactive for 9 hours” could trigger before the set time and not result in a trigger

Using “zone inactive for 2 hours” would trigger unwanted if she gets up early

Good point

My “man down flows are operational for about a month now.
Very satisfied with how it is working.

Warning::
As @robertklep mentioned, homey is not a system that you should fully depend on (lifethreatening situations or burglar alarm). It is lacking fall back mechanism like battery backup (there are solutions) and fallback communications (When Wifi drops)

But is is a great way to monitor.

Goal:
I want to be alerted when something might have happened to my mom.
She is living on her own (which is also a precondition for this setup)

Cost:

• bought a second hand homey pro 2019 (€70)
• 5 philips hue motion sensors (5x€29 black friday)
• direct to homey so no hue bridge

My setup:

• I placed 5 motion sensors in 5 rooms, every room is a zone in homey
• make sure the motion areas are not overlapping. (Position the sensors back to back or make sure there are walls blocking the view. (Makes it easier)

Determine the location

I created 2 (advanced) virtual devices.
This way I can quickly see where my mom is (if needed)

The “whereIsMom” flow sets the last location she was detected and timestamp

• It sets the value (WhereIsMom3) that is shown on the virtual device
• And stores it in variable (WhereIsMom)

The “whereWasMom” flow sets the last location that turned inactive and timestamp

• It sets the value (WhereWasMom3) that is shown on the virtual device
• And stores it in variable (WhereIsMom)

Sent an alert
I created a “broadcast” flow so I can easily include multiple persons in the alert without having to change all the flows:

Its an alert, so sending multiple push messages that would attrackt attention…
Planning to extend it with the whatsapp homey app, so I do not need to install the homey app for all

The alert also shows where she is and when.

Man down in bathroom flow
Situation: Mom did not get out of the bedroom in the morning
(The bathroom can only be entered via the bedroom)

Situation: Mom is unable to get out of the bathroom, but still moving

Situation: Mom is unable to get out of the bathroom and continuously moving

Situation: Mom is still in the bathroom, but not moving

Man down, did not get out of bed
Mom did not leave the bedroom in the morning
