Thanks for your questions.
Sorry for my late response here. Our community website could not log in because of some upgrade issues.
Even I have replied you by email. To avoid you didn't receive my email, reply again on the community.
From this post Thread and HomeKit Solution, I see that KW40 series can be used for Homekit and MFI. But KW40 series are not recommended for new designs. KW41 series as the replacement of KW40, I think KW41 can also be used for Homekit and MFI.
All support for MFI is made trough Professional Services. More information can be found on the following link:

I hope above information can help you.
Have a nice weekend~
Best regards,
Christine.
