I have a smart camera device that can be added as an accessory to a homeKit. I want to implement a subset of functionalities of the smart camera behind a paid subscription or a paywall. Anyone aware if this has been done before? i.e. conditionally exposing services on a Homekit accessory as a paid feature? So far neither have I seen any such examples and also nowhere in the apple docs does it say that you can't. So looking for any information regarding this. The questions are Does apple support paid services in Homekit accessories? If not, does it prevent people from implementing customized solutions?
