Please help me not return ST, how can I integrate with my DSC alarm?

That’s why I mentioned a virtual switch. :sunglasses: It’s The same way you use Amazon echo or Google home to change a mode.

You create a virtual switch.

there is already a smart app in the marketplace section of the SmartThings mobile app that is “switch changes mode”

You can also just have a routine start because the switch turns on, and that lets you change the SHM alarm state that way. Just remember to turn the switch off again in the routine so it’s ready for the next time. :sunglasses:
