@ obmd1,
We have not added support for the multi-sensor on any of the UI's, it has support only through LCD so far. Once you add any multi-sensor it would give you an option to select type of the sensor, if you select multi sensor then it would show as "Unsupported Device". However, if you select it as motion sensor then it would show you as supported because the support is already added to it.
We are working hard to release the new update for the iOS. To my best knowledge, it is being tested now and would personally update the status once it is getting released.
