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.

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.

Make SmartThings “Smart” again!

Thanks for the recent update. I had a problem where my wife’s and I’s phones were not updating with the presence modes. This made it seem like we were always home and would never activate the away locked mode. Well I can say with this latest update it’s working perfectly. :-) thanks for making it work with IOS 11 and taking time to get it working again. Please keep SmartThings smart. :-) working great now and I have no problems. Easy way to check my home and tell what the current status of my house is. Love it. I was halfway across the country and the garage door had a glitch and went back to open status after wife left for work. I texted a friend and he stopped over and sure as heck, the door was open. He shut the garage door and made sure everything was safe. I was notified within 10-15 minutes and could find help within 5 minutes or so. Thanks SmartThings!!! This is what I was looking for. Keep it up.
