With the new software authentication available, would like to see HomeKit integration.
@jaye_wyo - If one does a search on Homekit here in the community forum one will find:
A comment that the software authentication may not be for commercial applications (e.g. Rachio).
Rachio probably can’t comment on Homekit functionality until the sprinkler profile is supported by Apple (it isn’t yet as of iOS 11.2.2).
And that Rachio was listed at Apple’s 2017 WWDC as one of the vendors to support Homekit in the future.
