It’s definitely something I would like to do, if possible however no plans or research have been done to incorporate HomeKit. Another issue is the app is developed using PhoneGap so a plugin/wrapper would need to be created to incorporate support. The good news is some authors have already begun developing such a plugin but the details on Apple’s HomeKit are still being unraveled so nothing is complete as of yet.
I wouldn’t anticipate this anytime soon however if it becomes we will likely do what we can to incorporate it.
