There is a Virtual Device Creator SmartApp. I see it listed in the new SmartThings app SmartApp section just like the SmartThings Home Monitor SmartApp is listed, but I’m not sure if that’s because I’ve already used it from the old SmartThings Classic app first.
I select the Virtual Device Creator SmartApp and give the new virtual switch a name and select done to save it. Then I can use the virtual switch as the trigger for Automations.
Quick example of using the virtual switch.
Virtual Switch Name: Home Security
Automation for Home Security Switch Off
If
Control device, Home Security = Off
Then
Change Security Mode = Disarmed
Automation for Home Security Switch On
If
Control device, Home Security = On
Then
Change Security Mode = Armed (Stay)
I can then use Alexa or Google Home voice commands to enable Armed Stay and Disarm the SmartThings Home Monitor via voice command. "Alexa, turn on Home Security" , "Alexa, turn off Home Security" .
