I'm hoping Garrett restarts development on AuthomationHD as it's still my primary app on all Android devices.
If he devices to fully move to a different platform (eg OpenHab) all I can hope for is that he decides in open the source or finds a worthy successor to take over development as it would be a shame to let such an excellent product die. If Garrett decides to make an AuthomationHD for whichever platform he moves to that will be a strong draw for me to evaluate that platform.
If/When development restarts, I hope he adds the ability to merge multiple Vera's into one like ImperiHome seems to do. I just added my Ui7 to the existing Ui5 one already in that app and it is showing both at the same time. Granted, I have some duplicate rooms and some duplicate camera's but I can now see all devices on both Vera's without having to switch between them. As in preparation for the Ui7 migration I have been adding all new devices to my Vera 3 running UI7 (Only if they cause issues will the be moved to the Vera 3 running Ui5) and that requires having multiple tabs open on my desktop or in AuthomationHD, swap between controllers.
