Yes, I am just looking for a chime sound when a contact sensor, typically on a door, opens. That’s a very popular use case and we used to get a lot of questions about it, particularly from families that have a potential “wanderer” or from people who wanted an alert when the front gate was opened, but something that sounded more like a doorbell. There’s a wiki article on it that’s been there for a couple of years and has been updated multiple times.

after the Aeotec doorbell and the Dome chime came out, those became the two most popular solutions, and they were pretty simple as long as you used one of the custom DTHs. And then echo added even more options, including custom voice announcements.
However, we now have people asking for one that does not require any custom code and that will work with the new app. So I’m just trying to collect information to update the wiki for those restrictions. 
It’s true that the ADT panel sounds can only play for the ADT dual logo sensors? What other choices are there besides that triple-beep?
