On this page it says that the S200B button is not compatible with Matter. https://www.tp-link.com/en/support/faq/3754/

I use python-kasa to connect directly to the hub.

We can remotely connect to a Tapo Hub and view data from connected devices using the "getChildDeviceList" method. For T110 contact sensors, we can see if they're open or closed using the "open"...

The H200 hub's speaker isn't very powerful. It would be very useful to be able to connect external speakers with an amplifier.

This feature is required for all devices. It should at least be available with a Tapo Care subscription.
