@craig-2 we are internally experimenting with our new hub sdk features (https://community.flic.io/topic/18536/new-flic-twist-features-for-the-hub-sdk) together with home assistant (communicating over mqtt) and it works pretty good. So that is one option.
The other option is to expose devices in home assistant as matter devices, as explained here https://community.flic.io/topic/18457/home-assistant-twist-another-angle.
