Which firmware for IOS companion?

Which is the minimum firmware for using IOS companion in an IPad?

Thanks, so my IPad with IOS 10.3.4 is supported? If yes, why all the custom cards are not supported? They are not shown in the app…

According to that document. Yes.

I guess that would be a question for the custom card developers.

Hmm… I don’t think so as all the custom cards have the same issue…
