@wbhartmanii Sure thing.
No promises on dates but something we will deliver hopefully this year.
The short list is:
- http://myplantlink.com/
- http://edyn.com
- http://www.koubachi.com/
- http://www.parrot.com/usa/products/flower-power
I’d love to be working on this full time but we are working on a full rewrite of the mobile and webapp (2.0) among other integrations and top-secret projects 
So, when it makes sense we will build and deliver this integration. Should be very straight forward.
Thanks and let us know if you have any other questions or other moisture sensors not on our radar.
To be honest there doesn’t seem to be a clear leader in this space.
