I actually have a SmartApp that someone else wrote and I customized prior to writing BigTalker to do this in my home (Door Left Open). It repeats up to 10 times (configurable); however I haven’t written my own code to do this into BigTalker yet. I intend to add this and door knock announcements when I get some time to devote to it. I’ve been busy with work and family for quite a while and haven’t had the time needed to put into it.
