I don’t use the SmartThings Mobile App very often as it’s just clunky and slow and the UI is very poor to check the Status of anything. Instead, I use ActionTiles which is accessed via Browser. You can view the Status of all your SmartThings Devices.
On top of that, I’m running Android and through an IFTTT Applet I can send myself an email for any Push Notification received from the SmartThings Application. I’m sure there are other ways to accomplish this as well, but this is one way that you don’t need to use your phone with SmartThings.
If you want to see how I defined my ActionTiles Panels to see and access all my devices and where I operate my SmartThings from my phone, my tablets, my desktop you can view them here:
