Hey friends!
After a ton of time and research, we’ve determined that the HomeKit integration can have difficulty connecting to mesh routers depending the physical configuration of your home’s network. We ask that you continue to reach out to our support team to troubleshoot all HomeKit connection issues. The team has had success getting most integrations reconnected. We apologize for the incredible headache this has been and appreciate all the work everyone has done to work with us to learn and troubleshoot to get to this conclusion.
