Z Wave Door-Open Chime support (Philio?)

If you just want a chime when a door opens, that’s easy. Use a regular contact sensor, then have another device make a sound at that time. I have a zigbee contact sensor on my gate, when it opens SmartThings sends a text to my phone, I get notification. (It also pings on my apple watch). You could also have it call a Skype number and use that ringtone.

Other people use a speaker to play a sound or a voice notification using the generic DLNA renderer.

The doorbell challenge is getting the noise when the door hasn’t opened.

Anyway, take a look at the doorbell FAQ for many more ideas.
