Looking for suggestion on how to handle a wait for time or sensor

That works too. Only difference is the first notification would be the same as all the repeats, instead of a unique notification when she first leaves the house.

Nice thing about Webcore is being able to add in other stuff, like to set a time variable when she leaves, and then compare that time to present time to get how long she has been gone for each notification. Then when home, it could notify, "Mom is now home after being gone for x hours and x minutes. " Webcore makes time calculations pretty easy.

But the notification app can certainly work for this.

good point... i do actually have a time variable and say how many hours and mins gone
