HomeKit Notifications when Door Left Open

Hello,

I have door sensors and what I really need them for is not security, but to get notifications when I am away from home if a door is left open too long. As near as I can figure, there's no way to do this without running a home bridge server, which I'm not interested in doing.

This is really frustrating. Does anybody know where to pull it off?

thank you,

Shawn
