One more option if you’re willing to copy and paste someone else’s code
If you’ve been waiting for the OAuth problem to be fixed so you can use one of the third-party rules engines, I did just want to mention one new alternative. This one demonstrates one of the real strengths of SmartThings, which is that community members can develop new smart apps and make them available to others.
Because this one works entirely within the SmartThings, it is not affected by OAuth. However, you will have to copy and paste The code into your own account.
The third-party options are very nicely polished and offer a lot of functionality and are easy to install.
However, if you’re willing to copy and paste someone else’s code, One community member has created a smart app that will let you more easily combine multiple rules. So something like “my wife is home and it’s after 10 PM and someone entered the bedroom” then do something. It’s called “rule machine.” Again, it’s going to look more techy than the third-party solutions because it’s limited by the options available to something that runs inside the SmartThings mobile app, but it’s worth considering. @bravenel has contributed a lot of code to the community over the past two years, and is well known for being able to solve very complex multiple device scenarios.
To begin, take a look at the FAQ on using custom code. Then if that sounds like something you’d be willing to try, continue to the actual thread about rule machine.
