I don’t think you’ll ever get a “All clear” message. There is no such thing as a guarantee with today’s technology.
The biggest problem I’ve seen is incomplete processing of routines that leave things in a mish-mashed state: the system showing disarmed in the cloud, but still armed, locally. The developers are aware of it, and are responsive to the importance of this being fixed. And SmartThings does have an active core of developers. Extrapolate from this, as you will.
I use ST for security, and am generally, quite happy with it. But, as I’ve said elsewhere, I bought into SmartThings hub primarily because of my interest in IoT, not specifically for security. The security was an add-on bonus. I’d like it to be more reliable, but if the reliability issues are mainly focused on triggering an alarm reaction when the home should be disarmed, I’ll continue to use it, and not seek other functionality.
