@bdiederik@kde@kde Rather than specifically HASS focused, perhaps it would make sense to do Matter integration? Given HASS support for that protocol, you should end in the same place, but also available to a broader ecosystem.
It would seem the fruit company with their thread/matter cert test on phones & laptops are headed that direction as well. So on top of serving the existing commuity, it could help people considering a switch - by presenting same capabilities.
