Question about smartthings

[greg]

1. Yes you can play any file if you add it to your sonos queue (and keep it there). The library where the file is stored just has to be available (computer, NAS). There are also stock sounds that are in the cloud that always work. As well as text to speech that always works.
2. I believe drop cam is the only one that is working right now, yes you can see the image on your phone
3. If you are asking about z wave devices you are not even going to pair to ST, then sure. If you are talking about secondary controllers. Check out this thread.

Will Secondary Controller Still Work?

I’ve had an Intermatic Home Settings HA07 controller for years which I mainly use to automatically turn on outdoor lights at dusk and off at a set time in the morning. I realize that I can’t pair the lights that it controls with ST’s because it is a master controller. My questions are: Is there a way to have the HA07 still control the lights as it does now, but also have them controlled by ST’s? If so how do I do that?
