The system itself works pretty well. I just moved it off of the plant link hub which was working fine into the smart things hub which was a bit more difficult to get up and running but the range is much greater.
I wish there was some tighter integration with SmartThings as far as what was displayed and push alerts. We will see how it goes since I have only had the sensors paired with the V2 hub for a few days.
I just got spruce (formerly Eve) and am dying to try it out.
