If you are a new user of SmartThings or ADT | SmartThings, please download the new “SmartThings” app instead of this “SmartThings Classic” app.

SmartThings lets you monitor, control, and automate your home from anywhere in the world. To get started, simply purchase the SmartThings Hub, download the new "SmartThings" free app, and add as many connected lights, locks, sensors, and devices to create a smart home that matches your unique personality.

Continued use of GPS running in the background can dramatically decrease battery life.

4.5 Stars....Almost perfect

This is my first attempt at setting up a smart home system. I set it up for my elderly paraplegic grandmother who lives alone. Initial setup was rather intuitive and the basic options met most of our goals. It’s nearly a perfect app for the system. The only hiccups are in the confusion between using the “new” app vs the “classic” app (the classic app seems much better), I do wish that the Ring video app could be integrated since it can be confusing having to switch back and forth from viewing the video then unlocking the door. Setting up automations was a breeze and I like that it monitors the battery level on the sensors although I was a little disappointed that it couldn’t tell me which batteries to buy for those sensors (which happen to be SmartThings branded sensors). Lag isn’t bad, around 3 seconds. The “smart apps” are a bit confusing, such as the smart locks app but decent enough. All in all, I think that SmartThings is pretty good considering I was able to set it up, figure it out then teach both an 84 year old woman and my 65 year old dad how to use it all in just a few hours! 4.5 stars.

Happy User but Room for More

App works as it is described and does well. I am happy with the overall performance of the app but there’s a need for more. The ability to set a bracket for functions to happen, ie. turn on this light when someone arrives from sunset to sun up. Currently when I set it to perform that function it works the first day (after sunset) and then all the time after that not stopping for sun up the next morning. Another nice additional would be the ability to “pause” a function or smartapp without having to delete it completely and then later it up from start again. Also the ability to rearrange the order of “my home” and not just have it alphabetical. Just my wish list here. Overall loves it and look forward to expanding my system soon.

Works as Advertised!

I read of everyone having all these problems and I sit here thinking this stuff is working just like they said it would. I did have a few issues pairing the "things" with the Hub but most of that was all this is brand new to me, but videos and reading FAQs helped bring it all together and now I have a system that has met my every need. No app issue - update or not. I give it two thumbs up!

One Year of Usage
After one year, I am still a believer of the SmartThings app and hardware. I had one issue with some of the motion and door sensors that quit working. At last indication, the batteries were showing at least 30% to 40% charge level when they quit working. However, a quick call to tech support advised to change batteries and see if that worked. It did, so the battery charge level may read incorrectly, but other than that there have been no issues. I am sure an app update could correct that. Still works as advertised for me.
