I would probably have made a similar suggestion to yours a few months ago, but I have multiple concerns about SmartThings right now from a customer support standpoint.
In particular, just since 1 January, they seem to have changed the way you get support, and much of the new process is broken at the time of this writing! 
I personally just can’t justify investing more money with a technology company that can’t even set up a decent helpline system.
For a look at some of the details about how hard it is to get customer support right now, see the following thread:
