HMS Hub--limit to number of V1 Sensors?

I noticed that there was an option in the Account section of the Wyze app to create a “home” which I did, with some basic information. Today I noticed the app had added a number of my V1 sensors to that “home” but not all of them. Is there a limit to the number of sensors (V1, V2 or a combination) that can be used with the HMS hub? I know there is a limit to the number of cameras (5 I believe) but I haven’t seen any mention of a sensor limit.
