The old SmartThings Classic app’s SHM has a ‘Custom’ section. In the Custom section, I can setup any sensor (motion, multipurpose, vibration, etc.) to trigger capturing video from selected cameras.
Example of Classic app’s Custom SHM feature; if the front door multipurpose open/close sensor opens when mode is away (Armed, Away) or night (Armed, Stay), then it will start capturing video on the living camera. That way the video recording will start capturing video before anyone is sensed by the living room camera’s built-in motion sensor alone.
Another example; the old app’s Custom feature doesn’t require the system to be in any Armed mode to do stuff, so it could even be in Disarmed mode, and the video recording could still be triggered. That way I could have the system Disarmed, and still trigger recordings so you can capture the Landlord or a contractor inside when your away.
As for the new SmartThings Connect app’s Automation creator, all I see is that I can turn on the Arlo cameras and nothing else. Only the SmartThings & my old DLink cameras offers recording. And the new app’s STHM, it’s not granular at all since I have to select all cameras to start recording irregardless of the sensor that triggered it, and I have to be in Armed (Away or Stay) for it to start recording anything. So, they just have to include Arlo cameras recording in the new Connect apps Automation creator and I could then use it.
