I recall there was an HE app by BPT World but its no longer maintained:
Is there anything you can do just using an intruder alarm system? On the systems I install in the UK (Pyronix) , that functionality has been added in recent years. I can set an occupancy timer on any of the sensors. If none of the sensors in the group trigger before the timer expires, various actions can be configured, one of which is to send an alert to the app on a family members phone.
- discrete motion sensors with LED's disabled
- contacts on the main doors
- water level sensor in the toilet cistern
- power monitoring outlet(s)
That ensures someone is moving, getting fresh air, going pee pee and watching TV (all essential day to day especially TV!)
