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

System close to wonderful but rendered useless often with no support

With the system in place two years now. And in that time many of the devices have become unavailable for no reason. They have needed to be reset and had new batteries despite battery power being 70 to 80%.
My main gripe that is rendering my security totally useless is that previous routines, I.e. to turn off security at 3:20 when my daughter returns home from school was removed as we were on summer holidays and needed the security to remain on until we came home. The old routine of‘ back-to-school‘ does not appear in the app as I have deleted it, but Still turned off my alarm system. Email from support saying they will be in touch-no support whatsoever.

In response to system reply - your comments are not relevant to my review. You are neither reading reviews properly nor responding to feedback via the website. Not at all and showing why two stars is a fair rating.

Developer Response ,

Hello, this is Ellen with SmartThings support. I'm so sorry for the issues you've experienced with device connectivity as well as the changes with the new app that are different from Classic. If SmartThings Classic has more features that you need, then you can continue to use the Classic app. In the meantime, I will be passing on a request to add more features from the SmartThings Classic app to the new app. If you have not removed previous Routines from SmartThings Classic, they may still run but not show in the new app. Please update your review with your support request number and I'll be able to look further into this case.

You can also reach us at to chat with us or email us at to follow up with our support team.

Don’t spoil it!

Smartthings was the best flexible smart home automation system, until Samsung bought it and released Hub v3 and tried to implement its approach into it. Hub v3 is limited and miserable, the new app is so limited and closed compared to this original Classic app. If you want to keep the success of the original Smartthings’ team and build on it, then please don’t spoil the last peace which is this Classic app. Don’t remove features and compatibilities. On the contrary, add, fix and innovate. Let the original team do their magic and show respect to your biggest ground base of users who have invested heavily in the system and count on this app for serious life and security aspects. This is not a game or a trial and error experience. I took off one star only hoping you learn from mistakes and embrace your loyal users. And don’t spoil or kill this Classic app until you can figure out a matching or better new app.


Fantastic home automation system

Been using smartthings along with other products to automate my home for over a year now and I have encountered next to no problems with this system. I use Hue, Sonos, Echo, Nest and other smart devices which all connect great to smartthings however sometimes via the use of IFTTT. The devs roll out frequent updates to both the app and hub to add new features and security. In my opinion the best thing about ST is the community, if you can't find an app or a device handler in the app you can check the community forums and 9 times out of 10 someone will have developed one for you to use.
