I was kickstarter supporter and has been using it since the company's infancy, who has been quite responsive and prompt with customer care but I see that they have been awfully quiet and are no longer responding to any support request nor their software updated. Sesame app on iOS is over one year old and I'm now surprised that it works at all under new iOS. Hopefully they would bounce back and continue to make devices and services but right now I wouldn't count on them getting back with response. I will use my Sesame until it fails or a good alternative with HomeKit support emerges.
