Way to query home/away status via API?

I’d like to make my own custom integrations for my IP Camera. I’d like to enable/disable pushover notifications based on home/away status. Is this something that can be queried remotely?

You can create a SmartApp that exposes that type of information using http requests. home/away status could be Modes, or presence sensor data, either way you can get access to them.

Have you taken a look at this page yet?

It is a good starting point.

Does your camera have the capability to query an external source?
