I am betting that it isn’t all that different, just that some may be depending on it more than you. I see the principle requirements of a home automation system to be:
1.) Energy Savings. But having things left on when they’re not supposed to be doesn’t save energy.
2.) Convenience. But being woken up in the middle of the night by false motion alerts, having no hot water in the morning, or having lights that should be on but aren’t, is hardly convenient. Nor is having the mobile app not showing correct states, forcing me to have no less than four other third party apps on my phone to verify what is actually on or off, open or closed. Oddly enough, I don’t recall any of “them” ever lying to me.
3.) Security. Not everything is fool proof here, and a battery operated, wireless system should not be depended upon to be so. However SmartThings monitoring of it is, too often, an annoyance.
I came to SmartThings for the purpose of improving reliability over my old PL based system. I almost bailed when I discovered it was internet dependent, but I was willing to accept that access to the net was required (installing power and communication backup methods in case of failure in that regard).
What I was not prepared for were issues with the platform itself. Online systems can be (and many are) fast and reliable; just not SmartThings. The state of HEAVILY advertised integrations are bare bones at best, with only the bare minimum of capabilities supported. If the same mindset exists within the platform in general, it would go a long way in explaining all of the issues.
I’d give 2 stars to SmartThings, you’d give 5. It really just depends on what your expectations are. SmartThings is smart, quite clever actually, and I don’t see the cloud being all that much of an excuse as to why it is unreliable. What they designed, no matter how clever, is what is unreliable. At the time of purchase, when I voiced my concerns about it being cloud based, I was told it would be reliable. I expected it to be reliable. My expectations have not been met… hence the 2 stars. (c;
