In multiple places including Kasa's own FAQs, it is stated that the KD110 supports using multiple chimes. In at least one location, Kasa has stated a single KD110 will ring up to 20 chimes.

I have a KD110 still in box, with the intent to replace my existing doorbell. But since it doesn't ring my existing chimes, I need at least two more KD110C chimes to hear this throughout my house.

So, where can we get additional chimes, without purchasing an entire doorbell kit?
And if the KD110C isn't available for separate purchase now, when will it be available?

Thanks!
