Manufacturer App

Hi All,


Can someone help with how the manufacturer of the Homekit Accessory should behave in certain conditions?


1. Does the manufactrurer app of the Homekit accessory needs mandatory Login/Account creation? Is this defined anywhere? the manufacturer app pulls all the data of the acecssory from the Home app?

2. As the manufacturer app do or control some of the accessory secondary features that are NOT in the Home,

Does having a login to the manufacturer app makes difference in secondary user having access to the control of certain features of the accessory? Ex: if there is specific feature of the accessory managed through manufacturer app, when this particular "Home" is shared or given acces to control remotely to another user (who also installed manufacturer app) - how ro restrict the secondary user having all the 'features' of the accessory in their manufacturere app for that Home?

Thanks
